Description
Technical field
The utility model relates to a kind of downhole oil extraction device in the oil exploitation, is applicable to that the sucker rod pump mechanical oil recovery need be familiar with the oil well of oil reservoir output situation.
Technical background
Present most Oilfield using waterflooding extraction, general oil field all is made up of the different oil reservoir of permeability.In the waterflooding extraction process, the speed that water advances in oil reservoir is uneven, that is to say that high permeability zone is fast, and less permeable layer is slow.On producing well, just show as the moisture difference of well liquid of each oil reservoir output like this.For improving development benefit, people wish many extraction crude oil, few recovered water, and just there is the problem of a understanding oil reservoir in this.Be familiar with the occurrence of oil, present method is a lot.As method of testings such as isotope, carbon-to-oxygen ratio, well temperature, delaminating pressure testings; Block certain section oil reservoir by downhole tool in addition, singly adopt, change again after getting clear and adopt another section oil reservoir.Be familiar with oil reservoir at mechanical oil well also useful separate extracting pump in conjunction with downhole tool, two-tube as double pump, it is fine, but is subjected to the restriction of borehole diameter, and complex process to consume steel many.Also useful double pump branch is adopted and is closed out in conjunction with down-hole switch, closes one deck during metering, and its operation requires high, trouble, and deep-well is realized difficulty.Also useful hollow rod is in conjunction with separate extracting pump, and beam hanger, oil pipe branch are adopted and told, but need to change existing sucker rod, and the suction degree of depth also is subject to certain restrictions.Above method all needs in conjunction with the downhole card water plugging string.
Summary of the invention
The purpose of this utility model just provides a kind of extracting device of oil of layering understanding oil reservoir, and it need not to change existing well lower tubular column structure and just can finish.
The purpose of this utility model is achieved in that the extracting device of oil of layering understanding oil reservoir is made up of delivery connection, tap, upper packer, eccentrically arranged valve main body, tube connector, lower contact, hollow slide bar, sealed tube, plunger, pump barrel, tap, upper packer, eccentrically arranged valve main body, tube connector, lower contact are threaded successively, have oil outlet on the tap; Have intercommunicating pore and inlet opening on the eccentrically arranged valve main body, in the eccentrically arranged valve main body, be provided with draining valve and last inlet valve; Eccentrically arranged valve main body upper end internal thread is connected with sealed tube, the lower end internal thread is connected with pump barrel, and the pump barrel bottom has the hole, and standing valve is housed on it; Be inserted with hollow slide bar in the middle of sealed tube, hollow slide bar upper end picks out oily joint, the bottom connects plunger, and plunger is provided with upward-traveling valves and lower travelling valve, and plunger seals slip in pump barrel.
The utility model is still used oil pipe, sucker rod, the oil pumper of crude oil well, utilizes oil pipe and the oil sets annular space well liquid of the two-layer oil reservoir of extraction respectively, and is intuitively accurate to the understanding of oil reservoir production status, and cost is lower, convenient directly perceived.

The specific embodiment
As shown in Figure 1, the extracting device of oil of layering understanding oil reservoir is made up of delivery connection 1, tap 3, upper packer 5, eccentrically arranged valve main body 7, tube connector 17, lower contact 19, hollow slide bar 12, sealed tube 6, plunger 14, pump barrel 13, tap 3, upper packer 5, eccentrically arranged valve main body 7, tube connector 17, lower contact 19 are threaded successively, have oil outlet 4 on the tap 3; Have intercommunicating pore 9 and inlet opening 11 on the eccentrically arranged valve main body 7, in eccentrically arranged valve main body 7, be provided with draining valve 8 and last inlet valve 10; Eccentrically arranged valve main body 7 upper end internal threads are connected with sealed tube 6, the lower end internal thread is connected with pump barrel 13, and pump barrel 13 bottoms have the hole, and standing valve 18 is housed on it; Be inserted with hollow slide bar 12 in the middle of sealed tube 6, hollow slide bar 12 upper ends pick out oily joint 1, the bottom connects plunger 14, and plunger 14 is provided with upward-traveling valves 15 and lower travelling valve 16, and plunger 14 seals slip in pump barrel 13.
During use, earlier lower packet 27 is lowered to down between oil reservoir 30 and the last oil reservoir 31, this device is connected with oil pipe, delivery connection 1 is connected with sucker rod 25 by on-off connector 26, as shown in Figure 2.Upper packer 5 in this sample device just will be gone up oil reservoir 31 and separate with the casing annulus of last oil reservoir more than 31, and the upper and lower oil reservoir that lower packet will need to be familiar with was opened in 31,30 minutes.The ground oil pumper drives sucker rod 25, on-off connector 26, delivery connection 1, hollow slide bar 12 and plunger 14 and pumps.When plunger 14 was up, lower chambers 20 volumes increased, pressure reduces, and standing valve 18 is opened, and oil flows to into lower chambers 20.Meanwhile, upper chamber's 21 volumes reduce, and pressure increases, and last inlet valve 10 cuts out, and the oil stream unlatching of upper chamber 21 is gone up draining valve 8 and entered sleeve pipe 23 by the cavity 22 that upper packer 5, sealed tube 6 and shunting top connection 3 form from oil outlet 4, discharges ground.When plunger 14 was descending, lower chambers 20 volumes reduced, and pressure raises, and standing valve 18 cuts out, upward-traveling valves 15 and lower travelling valve 16 are opened, oil from lower chambers 20 enter plunger 14, hollow slide bar 12 enters oil pipe 24 from the oil outlet 2 on the delivery connection 1, discharges ground.Meanwhile, upper chamber's 21 volumes increase, and pressure reduces, and last draining valve 8 cuts out under the gravity of the fluid column of cavity 22, and last inlet valve 10 is opened, and crude oil enters upper chamber 21 from the annular space of oil pipe 24 and sleeve pipe 23 by the fuel feed hole on the eccentrically arranged valve main body 7 11.This device will descend the fluid of oil reservoir 30 to be extracted into ground through oil pipe 24 like this, and the fluid of last oil reservoir 31 is extracted into ground through oil sets annular space.Can measure the output of each layer on ground, chemically examine moisture situation, reach the purpose of intuitively, accurately being familiar with different oil reservoirs.
