Description

Stratum water filling monitor
Technical field
The utility model relates to the used stratum water filling monitor of oil extraction in oil field field water filling.
Background technology
In the oil extraction in oil field field, in order to improve recovery ratio, need for a long time to the stratum water filling.In the injecting process, need quantitative injection is carried out on the stratum.And individual layer injection flow, tubing pressure and strata pressure are to record respectively under various different technology conditions by multiple instrument, then carry out analysis interpretation.Original method of testing can't obtain strata pressure and tubing pressure during water filling simultaneously, can't obtain to inject again flow when stopping annotating.Test process affects water-injection efficiency, tests respectively also being difficult to obtain unified True Data under the various process conditions, finally may mislead formation evaluation, and waste resource and the energy do not have the effect that improves recovery ratio.
Summary of the invention
The utility model provides the stratum water filling monitor of a kind of comprehensive monitoring stratum water injection parameter.This stratum water filling monitor has the function that under normal water filling state long-term test and record individual layer inject flow, tubing pressure, strata pressure and temperature, utilizes the data of fetching playback behind the ground, but the suction situation on accurate analysis stratum.
The technical solution of the utility model is: this stratum water filling monitor, comprise pulling head, pulling cam, apparatus subject, main body cup, battery sleeve, water nozzle and water nozzle lid, and above-mentioned each parts are successively thread seal connection from top to bottom; Tubing pressure sensor and strata pressure sensor wherein are set in the apparatus subject, between pulling cam and tubing pressure sensor the pressure transmission hole that is communicated with are set, the strata pressure pressure transmission hole that is communicated with the strata pressure sensor in the sidewall setting of apparatus subject; The circuit cavity is set in the described battery sleeve, the built-in temperature measurement circuit of circuit cavity, differential pressure flow sensor also are built-in with the pressure signal of tubing pressure sensor, strata pressure sensor, differential pressure flow sensor and temperature signal collection, record wiring board in addition; The bottom of water nozzle arranges inlet opening, and the sidewall of water nozzle arranges fluid hole, and the inner chamber of water nozzle and differential pressure flow pressure transmission hole are connected.
The utlity model has following beneficial effect:
1, can realize the water injection well long term monitoring: in eccentric injection mandrel, drop into this stratum water filling monitor, be positioned over for a long time the down-hole, test and record laminar flow amount, tubing pressure, strata pressure and temperature under normal water filling state, fetch playback of data behind the ground, can accurately understand the slow situation of change of the water absorption character on each stratum, overall understanding stratum technical data, the suction of accurate analysis stratum is for water injection technology provides the stratum technical data;
2, can measure reverse flow: during water filling, measure reverse flow by the flow that pours in down a chimney of quantitative measurment high pressure zone, during well-flushing, can measure the well-flushing bypass flow;
3, can measure stratum suction indicative curve: after dropping into this instrument and beginning to measure, adjust the ground water injection pressure, can accurately draw accurately stratum suction indicative curve, be used for the multiple uses such as geological analysis, construction evaluation, water filling allotment.
Description of drawings
Fig. 1 is the utility model agent structure schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this stratum water filling monitor comprises pulling 1, pulling cam 2, apparatus subject 3, main body cup 4, battery sleeve 5, water nozzle 6 and water nozzle lid 7, above-mentioned each parts from top to bottom successively thread seal connect; Apparatus subject 3 interior tubing pressure sensor 9 and strata pressure sensors 10 of arranging wherein, the pressure transmission hole 8 that is communicated with tubing pressure sensor 9 in the 2 interior settings of pulling cam, the strata pressure pressure transmission hole 11 that is communicated with strata pressure sensor 10 in the sidewall setting of apparatus subject 3; The described battery sleeve 5 interior circuit cavitys 12 that arrange, circuit cavity 12 built-in temperature measurement circuits, differential pressure flow sensor 13 also are provided with the pressure signal of tubing pressure sensor 9, strata pressure sensor 10, differential pressure flow sensor 13 and temperature signal collection, record wiring board in addition; The bottom of water nozzle 6 arranges inlet opening 17, and the sidewall of water nozzle 6 arranges fluid hole 15, and the inner chamber 16 of water nozzle 6 is connected with inlet opening 17, and connects with differential pressure flow pressure transmission hole 14.Above-mentioned pulling 1 is conventional structure.
After instrument drops in the eccentric injection mandrel, tubing pressure sensor 9 utilizes tubing pressure pressure transmission hole 8 pilots of cam below to record tubing pressure, strata pressure sensor 10 utilizes strata pressure pressure transmission hole 11 pilots of side to record strata pressure, differential pressure flow sensor 13 utilizes differential pressure flow pressure transmission hole 14 pilots of its below to record differential pressure flow, circuit in the circuit cavity 12 records temperature, pressure signal and the temperature signal of the wiring board collection in the circuit cavity 12 and record tubing pressure sensor 9, strata pressure sensor 10, differential pressure flow sensor 13.This stratum water filling monitor contour structures is equivalent to common eccentric plugging formula, can pack into and drop into behind the water nozzle in the eccentric injection mandrel, test and record laminar flow amount, tubing pressure, strata pressure and temperature under normal water filling state or when well-flushing, profile control, acidifying, pressing crack construction, fetch playback of data behind the ground, but accurate analysis stratum water filling situation or condition of construction.
This stratum water filling monitor has following main feature:
This instrument is a kind of formation parameter detecting instrument that can measure simultaneously tubing pressure, strata pressure, individual layer flow and temperature, for analyzing formation properties, determines that water absorption character provides effective foundation.The metering of flow individual layer is without diminishing method.Flow is accurate zero point, and it is more accurate that low discharge is judged.Tool length is short and small, and is the same with common blanking plug, and pulling is convenient, need not special testing equipment.Can measure minus flow.Differential pressure flow is measured the mode measuring flow, attonity parts, electrodeless electric shock, anti-soil, anti-corruption, overload-resistant, reliable operation, the operation steady in a long-term of circuit power consumption low energy.The measuring media composition is without impact, and test result is mass flow.Instrument is inserted the stagnant water mouth, is equivalent to single channel retaining pressure meter or binary channels retaining pressure meter, can be used for delaminating pressure testing and tests envelope.Do not consider flow and tubing pressure in the instrument signal, be equivalent to pressure gauge behind the mouth, do not consider strata pressure, instrument is alternative various well flow meter then.
