Description
Technical field
The utility model belongs to natural petroleum gas field technical field, and in particular to a kind of production suitable for more testing well section
Liquid section plane test device.
Background technique
Producing profile testing is a groundwork of oil field development, is to understand pay interval to produce liquid condition important means.
The purpose is to the situations produced to oil/gas well to carry out implementation dynamic monitoring, the oil, gas and water three-phase fluid in timely test pit shaft
The important parameters such as relationship, single layer yield, pressure provide foundation for rational exploitation and measure operation.
In existing horizontal well produced fluid cross section method, mainly using coiled tubing, crawl device, oil pipe as conveying work
Test equipment is delivered in the horizontal segment of horizontal well by tool.Test equipment does not mainly need individually cable by cable connection
Using memory-type instrument, test mode mainly pass through cable or oil pipe above mention dragging test equipment tested.It is oily when test
The normal production of well relies primarily on oil well self-spray or carries out the production of machine pumping and simulation pump production using pumping unit by decentralized wellhead.
Existing horizontal well produced fluid cross section method is primarily present following deficiency:
It is tested firstly, being required to dragging test equipment when test, the data different time Jing Guo different level section
It pieces together, it is believed that be each section of same time point of production liquid data, there are biggish errors.Its secondary realization working condition
The dragging of lower test equipment belongs to production and test cross-operation, and the test macros such as cable, coiled tubing and pumping pipe string are side by side
Among pit shaft, cable and coiled tubing occur to squeeze wound touch it is disconnected or wind it is stuck happen occasionally, the safety and reliability of test
Receive serious challenge.Third is higher using the technical costs of the transmission technologys such as crawl device, coiled tubing, and instrument is more smart expensive to well
Condition requires height to be difficult to adapt to the requirement that benefit is developed.
Such as publication No. is the Chinese patent of CN105041294A, proposes a kind of " horizontal well coiled tubing conveying storage
Formula producing profile testing process ", this method measure different time not using test equipment is pulled by coiled tubing mode
The data that different time sections are tested are considered the production profile of the well same time, led by the production liquid data of same well section (well point)
There is error in the test result of cause.Also, there is the friendship of test with production system during dragging test equipment
Job execution is pitched, and nonflowing well original production system is not available, and needs mating just may be used for simulating the equipment normally produced
It is tested, the limitations such as entire test is complicated at high cost, accident easily occurs, and influence factor is more, and success rate is low.
Utility model content
The liquid production section test device that the purpose of the utility model is to provide a kind of suitable for testing well section more, for solving
It is in the prior art that different time, different level section are cutd open only with the test data of a memory-type liquid production section test device
Face data causes test result to there are problems that error, and needs section plane test reliability caused by dragging test string low
The problem of.
In order to solve the above technical problems, the producing profile testing dress that the utility model proposes a kind of suitable for testing well section more

Instrument group is serially connected with hanging device or anchoring device is used to for each set test equipment group being arranged in corresponding test well section.
The utility model is due to prefabricated memory-type module, test process institute in the test equipment group of each test well section
The cross-sectional data of test section is the data under same time unification production system, has been inherently eliminated conventional test methodologies
Splicing is carried out with different time sections test result to be equivalent to the test result of same time and cause error.
Dragging test string is not had in test process, it is only necessary to each set test equipment group is delivered to corresponding test lead and surveyed
Examination, there is no production systems and test macro to occur cross-operation parallel in the wellbore, substantially increases the reliable of test
Property, reduce test in there is the probability of underground risk.
Test use original production system, it is not necessary to matched simulated production ancillary equipment, both ensure that test condition with it is primary
Occurrence condition it is consistent while effectively control testing cost.The scope of application of the utility model includes inclined shaft, horizontal well and thick
Oil well, and adapt to high pressure flowing well, nonflowing well and heavy oil wells etc..
In order to which position of the assignment test instrument group in test well section further includes further positioning device, only need to determine
Position device is mounted on any position in liquid production section test device, can be by opposite between test equipment group and positioning device
Positional relationship determines the position of each set test equipment group, so that each set test equipment group is accurately transported to corresponding testing well
Duan Jinhang section plane test.
In order to adapt to the testing requirement of each test well section, further, the test equipment group further include it is at least one with
Lower test equipment: gamma instrument, position indicator, borehole thermometer, pressure gauge, flowmeter, water holding instrument and densitometer.
In order to adapt to the testing requirement of each test well section, the test equipment group further includes auxiliary tool, such as centralizer and
Flexible nipple.
In order to realize the connection of each set test equipment group, further, the attachment device is sucker rod or oil pipe, with use
Coiled tubing is compared, and cost substantially reduces.
