Example 1
Referring to fig. 1-3, the present embodiment provides a measurement and control method for rotary steerable drilling, which includes the following steps:
acquiring an error parameter model at a current drilling position;
comparing the error parameter model with a preset error standard model to obtain a comparison value;
Judging whether the comparison value is larger than a preset standard threshold value, if not, acquiring actual measurement coordinate information of the drill bit at the current drilling position;
Obtaining actual measurement error information according to the actual measurement coordinate information;
judging whether the actually measured error information is matched with a preset error database, if so, returning to the step of acquiring the error parameter model at the current drilling position;
If the comparison value is larger than the standard threshold value or the actually measured error information is not matched with the error database, detecting whether the drilling tool fault information exists; if yes, acquiring drilling tool replacement information, inputting the drilling tool replacement information into a preset drilling guidance model, and returning to the step of acquiring an error parameter model at the current drilling position; if not, acquiring the parameter correction value, inputting the parameter correction value into the drilling guiding model, and returning to the step of acquiring the error parameter model at the current drilling position.
In this embodiment, by constructing an error parameter model at the current drilling position, the error parameter model may be used to characterize the magnitude of the borehole error at the current drilling position (i.e. parameters such as diameter and direction of the borehole), then comparing the error parameter model with a preset error standard model, the error standard model may characterize the allowable error range at the corresponding drilling position, calculate the comparison value between the two, determine whether the comparison value is greater than the preset standard threshold, thereby determining whether the borehole error at the current drilling position exceeds the allowable error, if not, further measure, acquire the actually measured coordinate information of the drill bit at the current drilling position at this time, thereby calculating actually measured error information, i.e. coordinate error, by determining whether the actually measured error information matches with a preset error database, the error database includes data of allowable coordinate error ranges at different drilling positions, if so, the borehole error of the current drilling position and the current drilling position are indicated to meet the operation requirement, if the comparison value is larger than the standard threshold value or the measured error information does not match the error database, namely, either the borehole error of the current drilling position and the current drilling position error do not meet the condition, the fault information of the drilling tool is detected, so that whether the fault information is the error caused by the fault of the drilling tool is judged, if so, the replacement information of the drilling tool is obtained, namely, the recommended information of a new drilling tool (comprising the model of the drilling tool, the drilling parameters and the like) which needs to be replaced is obtained, the drilling tool comprises a drill bit penetrating through the drill string and the tail end of the whole borehole, the replacement information of the drilling tool is input into a preset drilling guidance model (used for guiding the rotation guiding drilling process of the drilling tool in the whole course), after replacement, the drilling operation is redirected, if not, the parameter correction value can be calculated according to error data (borehole drilling error or drilling position error) at the moment, and the parameter correction value is input into the drilling guiding model, so that the drilling operation can be continuously guided. In summary, in this embodiment, by identifying the borehole error of the current drilling position and the current drilling position error at the same time, the measurement accuracy can be improved, and by accurately checking the error cause, that is, the fault of the drilling tool or the error of the drilling process parameter is set, the drilling guiding model can be accurately corrected, so that the method is applicable to the complex working condition that the drilling direction is tortuous and changeable.
The data storage and rotation guiding system of the drilling guiding model can simultaneously promote oil and gas exploration and development, and based on the drilling guiding model capable of being updated in real time according to error data, the rotation guiding system can simplify internal sensors and circuit modules while realizing high-speed real-time communication and automatic three-dimensional guiding drilling, and can form an economic system structure.
As an alternative embodiment, obtaining measured coordinate information of the drill bit at the current drilling position includes:
constructing a reference coordinate system based on the drilling starting position as an origin;
Acquiring a first coordinate point or a second coordinate point of the drill bit at the current drilling position based on a reference coordinate system; the first coordinate point is the coordinate of the position of the corresponding inflection point in the well track, and the second coordinate point is the coordinate of any position of the corresponding curve track in the well track.
In this embodiment, when calculating the measured coordinate information of the current drilling position of the drill bit, the drilling start position (i.e. the initial position of drilling from the ground) is taken as the origin of the coordinate system to construct the reference coordinate system, when the drill bit moves to the corresponding inflection point position in the track of the borehole (i.e. the track path of the pre-drilled borehole), the inflection point position, i.e. the point where the drilling direction and the drilling angle change greatly, is a track point which is easy to have a large error, and therefore, when the drill bit passes through the corresponding inflection point, the inflection point position needs to be measured based on the coordinate point (i.e. the first coordinate point) in the reference coordinate system, and meanwhile, the track of the borehole is not necessarily a straight line, and the curve path may be drilled between the two inflection points, but the curve path is easy to have a large error.
It should be noted that, when the second coordinate point is selected on the path of the curve track, each coordinate point should be dispersed as uniformly as possible, so as to ensure the accuracy of the data. When the drill bit reaches the corresponding coordinate point to be measured, the work should be stopped, and the next action is carried out after waiting for the measurement result.
As an alternative embodiment, obtaining the measured error information according to the measured coordinate information includes:
inputting the first coordinate point or the second coordinate point into a preset borehole track model;
And acquiring the deviation degree of the first coordinate point or the second coordinate point and the borehole track model so as to acquire actual measurement error information.
In this embodiment, when the first coordinate point or the second coordinate point is measured, a coordinate point set is formed, and input is fused into the wellbore trajectory model, and when the input is fused, the coordinate points are aligned by the origin of the coordinate system, and a plurality of points corresponding to the coordinate point set are correspondingly distributed near the wellbore trajectory, so that the deviation degree of the first coordinate point or the second coordinate point and the wellbore trajectory model can be calculated, and the error condition can be effectively represented according to the deviation degree, that is, the actually measured error information can be obtained.
As an alternative embodiment, let the number of the second coordinate points be N, the expression of N be:
N=ε*L；
where N is an integer, ε is a conversion coefficient and is a constant, and L is the length of the curve trace.
In this embodiment, the number of the second coordinate points selected on the curve track is positively correlated with the length of the curve track, that is, the longer the curve track is, the more the number of the selected coordinate points should be, so the length L of the curve track can be correspondingly converted into the required number of the coordinate points by setting the conversion coefficient epsilon, and when the decimal point is calculated, the N can be taken as an integer according to the rounding principle, thereby ensuring the coverage and accuracy of the coordinate error data.
As an alternative embodiment, detecting the presence of drilling tool failure information includes:
Acquiring drilling tool state information;
Constructing a tool operation model according to the drilling tool state information;
Judging whether the tool operation model is matched with a preset tool standard model or not;
If not, there is drilling tool failure information.
In this embodiment, when the fault information of the drilling tool needs to be detected, the state information of the drilling tool (such as parameters of a tool vibration value, a tool wear amount, a tool response time, etc.) is acquired first, so that a tool operation model can be constructed, and the tool operation model is matched and compared with a tool standard model, and if the tool operation model cannot be matched, the fault condition of the drilling tool is indicated.
As an alternative embodiment, obtaining drilling tool replacement information includes:
acquiring a three-dimensional parameter and an environmental parameter of a borehole at a current drilling position;
inputting drilling tool fault information, borehole three-dimensional parameters and environment parameters into a preset stratum attribute association table; the stratum attribute association table is a table of attribute association of a preset stratum attribute database and drilling tool fault information, a well three-dimensional parameter and an environment parameter;
Acquiring stratum attribute evaluation parameters according to the stratum attribute association table;
and acquiring recommended drilling tool replacement information according to the stratum attribute evaluation parameters.
In this embodiment, when the drilling tool replacement information needs to be acquired, the three-dimensional parameters of the borehole (that is, parameters such as profile information of a certain section of the diameter and the length direction of the borehole) and the environmental parameters (including parameters such as temperature, humidity and formation hardness of the current drilling position) at the current drilling position are acquired, and meanwhile, in combination with the drilling tool fault information, the formation attribute evaluation parameter with the highest association degree is selected from the formation attribute association table, so that the formation attribute of the current drilling position can be acquired, further, the drilling tool to be replaced is recommended, and the guiding efficiency of the drilling operation is improved.
As an alternative embodiment, obtaining an error parameter model at the current drilling location comprises:
Acquiring drilling theoretical parameters, and constructing a drilling theoretical model according to the drilling theoretical parameters;
Acquiring environmental parameters at the current drilling position, and constructing a drilling measurement model according to the environmental parameters;
and comparing the drilling measurement model with the drilling theoretical model to obtain an error parameter model.
