Abstract
A hydraulic jet pump with sampler for oil well features that said sampler is installed between hydraulic jet pump and tail seat and the flow channel of sampler is communicated with those of said pump and tail seat. A pressure gauge is contained in sampling chamber for both sampling oil and measuring oil pressure. Its advantages are high correctness, high efficiency and low cost.
Description
The present invention relates to the oil production equipment of petroleum industry, particularly a kind of hydraulic jet pump that is provided with sampler is applicable to the oil well that all hydraulic jet pumps recover the oil.
In oil exploitation, use the producing well of hydraulic jet pump also can't obtain down-hole formation production fluid liquid sample at present, as: SHP2
1/2Hydraulic jet pump, SHP2 hydraulic jet pump are published in " oil gas has recovery ratio ", and 99 years the 4th phases, the 67-69 page or leaf can only obtain power fluid and mixed liquor liquid sample on the ground.Can not in time measure stratum output liquid water status, can only be by measuring power fluid liquid measure and well head output mixed liquor liquid measure, the moisture numerical value of down-hole formation output liquid is obtained in the moisture calculating of chemical examination mixed liquor, and sampling and pressure measurement can not carry out simultaneously, and the stream that pressure measurement refers to survey output liquid is pressed and the recovery pressure on stratum.Use said method to carry out the bearing analysis of stratum output liquid, influence factor is a lot: 1, the error in dipping of stratum production fluid, power fluid; 2, chemical examination is subjected to influence of various factors, as human factor, equipment performance etc.; 3, ground sample is subjected to the influence of stratum production fluid moisture content fluctuation.Be subjected to the influence of above factor, the accuracy rate of the liquid sample of surveying reduces greatly, makes the stratum production fluid that obtains untrue.Directly influence the production analysis of hydraulic jet pump producing well, bring difficulty for production and management.The production scene needs a kind of hydraulic jet pump that can directly obtain stratum output liquid liquid sample in the producing well down-hole, makes the oil sample of taking-up can accurately measure moisture content, for production management provides accurate data.
The objective of the invention is to make a kind of hydraulic jet pump that is provided with sampler, overcome the defective that can not draw oil sample in existing hydraulic jet pump producing well down-hole, make its can be in the down-hole direct extract sample, for production management provides accurate data, improve production management level.Other makes in the specimen chamber of hydraulic jet pump can put down pressure gauge, makes to draw oil sample and pressure measurement is carried out simultaneously.Increase work efficiency, reduce and produce and management cost.
Technical solution of the present invention is: form the hydraulic jet pump that is provided with sampler with former hydraulic jet pump and sampler, sampler is installed between hydraulic jet pump and the tailstock, the runner of the runner of sampler and hydraulic jet pump and tailstock connects.
The present invention compares with existing hydraulic jet pump, has following significant effect: 1, the same with the operation of former hydraulic jet pump, easy to be reliable.2, specimen chamber is simple in structure, and volume is big, is easy to assembling, and is cheap.3, in specimen chamber, can put into pressure gauge, not influence the ordinary production of oil well, accomplish sampling, pressure measurement carries out simultaneously.4, when obtaining the true output liquid in stratum, improve operating efficiency, reduced cost of production.
Accompanying drawing is the structural representation of the present invention in the underground work tube.
Below in conjunction with accompanying drawing the present invention is done further detailed description: lifting appliance 1, supported joint 2 and seating nipple 16, glue ring 13 and standing valve 19 are the ancillary facility of former hydraulic jet pump in the accompanying drawing.Be provided with the hydraulic jet pump of sampler, form by hydraulic jet pump 3, sampler and tailstock 12 etc.Sampler is installed between hydraulic jet pump 3 and the tailstock 12, and the runner of the runner of sampler and hydraulic jet pump 3 and tailstock 12 connects.Sampler is made up of last tap 14, sampler 9 and following tap 11, and upper and lower tap 14 and 11 is installed on the two ends of sampler 9 respectively, and last tap 14 upper ends connect water jet pump 3, and the lower end of following tap 11 connects tailstock 12.Sampler 9 is made up of reseting cavity, specimen chamber 17 and piston crank mechanism, and the upper piston 5 of piston crank mechanism, middle piston 7, lower piston 10 are connected with lower link 8 by last connecting rod 6 respectively.In the piston body of upper piston 5, middle piston 7 and lower piston 10 runner is arranged all.The outer sleeve of sampler 9 is connected to form reseting cavity and specimen chamber 17 with following tap 11, and spring 15 is housed in the reseting cavity, and piston crank mechanism is loaded on the centre of reseting cavity, specimen chamber 17 and following tap 11.Upper piston 5 outward appearance Cheng “ Shang " shape, its underpart is provided with the connection runner.Spring 15 tops place the lower lumen of upper piston 5, and the lower end places the bottom of reseting cavity, and piston crank mechanism wears wherein.Be provided with ball-and-seat 4 in the last tap 14, lower piston 10 moves up and down, and the runner of establishing in it opens or closes down the runner that tap 11 is communicated with specimen chamber 17.Following tap 11 sides are provided with the draining plug, are used for emitting the oil sample of getting.Be provided with the back pressure hole between last tap 14 and the water jet pump 3 and between following tap 11 and the tailstock 12." 0 " shape sealing ring sealing is all adopted in sealing place that respectively connects of this device, as the contact site of sealing ring 18 and piston crank mechanism and reseting cavity and specimen chamber 17 all adopting " O " shape hermetically-sealed construction, each junction employing screwed connection.
During site operation, the outer steel sleeve screwed connection of the upper end of last tap 14 and hydraulic jet pump 3, with hydraulic jet pump 3 from well head by power fluid through the oil pipe direct circulation above shaft bottom standing valve 19.When hydraulic jet pump 3 is started working, because the power fluid pressure on the upper piston 5 of this sampler is greater than the eliminating hydraulic coupling of the hydraulic jet pump that acts on lower piston 10, and the long-pending ratio of upper and lower piston cross-section is 1: 1, so promote the piston crank mechanism of this sampler, the elastic force that overcomes spring 15 moves down, the runner of lower piston 10 is communicated with runner on the following tap 11, the stratum production fluid promptly enters sampler 9 along the runner that has been communicated with, flows into the suction side of water jet pump 3 again through the runner of last tap 14.The sampler as long as hydraulic jet pump 3 work, stratum production fluid are just constantly flowed through, sampler becomes the only way which must be passed of stratum production fluid.After hydraulic jet pump 3 quit work, the piston crank mechanism of sampler was by the elastic reset of spring 15, and runner is closed.The stratum production fluid liquid samples of being got in the sampler 9 just can be circulated to well head through oil pipe by power fluid with hydraulic jet pump 3.Back out the draining plug from sampler 9, can emit the stratum production fluid of being adorned in the specimen chamber 17.When needing pressure measurement, pressure gauge is put into specimen chamber 17, with G.I.H of the present invention.Behind the work certain hour, propose ground with the present invention again, promptly record pressure simultaneously and obtain oil sample.
