Description
The present invention relates to the zonal pressure measurement of Petroleum Production well and oil recovery, water injection technology and instrument, specifically is a kind of bridge-type eccentric testing, injection-recovery apparatus that is used for oil, well.
When oil exploitation, often to measure strata pressure, calculate the oil reservoir reserves and carry out reservoir performance analysis, after the variation of the difference of more present strata pressure and original formation pressure and zonal pressure, adopt the method for water filling or oil recovery to determine production capacity, develop oil reservoir.At present, the method that usually adopts layering to measure and exploit improves the production efficiency of individual well, reduce cost, in water filling with when measuring, the most frequently used is eccentric center water-distributing technology, this technology be with storage adopt, the water filling layer separates, be lowered to eccentric blanking plug or water nozzle control water injection rate, yield at the flank of tubing string during operation, simultaneously also can send into pressure tester to the down-hole, finish test jobs, the subject matter that the device of this process using exists is:
(1) when utilizing the seal section test, because the seating nipple centre bore is that test channel also is a fluid course,, is only permitted seal section epimere pressure and be higher than the lower end if there is pressure reduction in the seal section two ends, if end pressure is higher than the upper end down, then can eject seating nipple to seal section;
(2) during test traffic, because the test channel of seating nipple is connected with the lower floor passage, can not singly survey certain laminar flow amount, the method that utilize interval to superpose can cause bigger error to substratum and full well yield than little layer;
(3) during test pressure, only can successively test from bottom to top, can not survey certain layer arbitrarily, when surveying certain stressor layer, the test section lower layer must stop to annotate;
(4) be limited to water injection well and use, oil well is inapplicable;
(5) owing to can not obtain the accurate data of single-interval test, can not accurately carry out the individual layer of oil well and join product.
The present invention seeks to the problems referred to above at the existing apparatus existence, provide a kind of when interlayer pressure changes tester can be by Shang Ding, can measure all intervals simultaneously, also can appoint and get some interval pressure measurement, the bridge-type eccentric testing of measurement of discharge, injection-recovery apparatus.
The technical solution used in the present invention is:
Bridge-type eccentric testing, injection-recovery apparatus are made up of fishing head 2, seating nipple 9, blanking plug 12, tester 3, seal section 4, locating slot 7, locating detent 8, centre bore 14 and eccentric orfice 15 are arranged out on seating nipple 9 main bodys, seal section 4 is housed in the centre bore 14, blanking plug 12 is housed in the eccentric orfice 15, it is characterized in that: the passageway bridge 6 that on seating nipple 9, also has up/down perforation; Centre bore 14 has two groups of sealings 5 up and down with seal section 4, and opposite position had the passage 16 that is communicated with eccentric orfice 15 between centre bore (14) and seal section 4 two groups sealed 5; Oil, water nozzle 11 are housed in the blanking plug 12, and oil, be communicated with the passage 16 of centre bore 14 with eccentric orfice 15 relative, oily, water nozzle 11 downsides are relative with eccentric orfice 15 connection annular spaces 18 passages with water nozzle 11 upsides.
The following technical scheme that the present invention also adopts:
Seal section 4 centers have the through hole of the passage relative with eccentric orfice is arranged 16, and through hole communicates with tester 3.
Seal section is two groups of sealing 5 employings four leather cup two way seals about in the of 4.
Three groups of sealings 10 are arranged in the upper, middle and lower of blanking plug 12.
Description of drawings of the present invention is as follows:
Fig. 1 is bridge-type eccentric testing, injection-recovery apparatus structural representation;
Fig. 2 is bridge-type eccentric testing, injection-recovery apparatus seating nipple tube generalized section;
Fig. 3 is bridge-type eccentric testing, injection-recovery apparatus scheme of installation.
Below in conjunction with accompanying drawing in detail the present invention is described in detail:
Bridge-type eccentric testing, injection-recovery apparatus are made up of fishing head 2, seating nipple 9, blanking plug 12, tester 3, seal section 4, locating slot 7, locating detent 8, centre bore 14 and eccentric orfice 15 are arranged out on seating nipple 9 main bodys, the seal section 4 that cooperatively interacts is housed in the centre bore 14, seal section 4 has two groups of sealings 5 up and down, two groups of sealings 5 can be adopted four leather cup two way seals, promptly from two ends and inside and outside side seal close up and down.Have the passage 16 that with eccentric orfice 14 be connected on the relative centre bore 15 with two groups of sealings between 5.The blanking plug 12 that cooperates with it is housed in the eccentric orfice 14, on eccentric orfice 14, have the duct 16 that communicates with annular space 18, there are three groups of sealings 10 upper, middle and lower of blanking plug 12, removable oil, water nozzle 11 are housed in the blanking plug 12, the passage 16 of oil, water nozzle 11 upsides and eccentric orfice and centre bore is relative and communicate, and oily, water nozzle 11 downsides and eccentric orfice and annular space 18 passages 16 are relative and communicate.The top of seal section 4 is equipped with tester 3, and tester 3 can be pressure gauge, flow meter or sampling tube, and seal section 4 centers have the through hole of the passage relative with eccentric orfice is arranged 16, and the upper end is communicated with tester 3.
On seating nipple 9, also have the passageway bridge 6 of up/down perforation.
The present invention connects oil pipe 20 and is lowered to predetermined stratum 17 when operation, with separator 22 each layer of shutoff oil jacket annular spaces 18, by fisher or steel cable 1 blanking plug 12,4 of seal sections are gone into seating nipple 9, when the seal section of tape test instrument navigates to target zone, other layer liquid stream passes through from bridge-type hole 6, when levels pressure changed, seal section and tester can not come off by last top.Oil, the pressure of water layer, liquid flows by the passage 16 relative with eccentric orfice on passage 16 that communicates with annular space on the eccentric orfice and the centre bore, and the tester 3 that the through hole at seal section 4 centers is delivered to the top of seal section 4 measures data, because seal section and blanking plug are many group two way seals location, can sealing fluid circulation road 21, other layer liquid stream can pass through from the bridge-type hole again, guaranteed to be connected on the multiple parameters that instrument on the seal section measures target zone, in pressure measurement, during measurement of discharge, the seal section of many band instruments is successively thrown in from top to bottom, after layering has been surveyed, successively take out from top to bottom, explain after the data playback, if need to survey full well data, can before layering is measured or after the layering measurement, instrument be lowered to pit shaft oil reservoir position.The tester of seal section in pressure measurement, test on when envelope seal section and connect pressure gauge; Connect electronics (or machinery) flow meter on during measurement of discharge; Connect sampling tube on during sampling, also can connect different instruments according to purposes, test mode adopts steel wire test, cable on-line testing all can.
The bridge-type eccentric testing device under situation about allowing, is not limited by progression at card, can reach more than 10 grades, pulling arbitrarily, tests certain one deck, still normally water filling of other layer.
Advantage of the present invention is setting safety and precise, can test arbitrarily certain layer, is not subjected to other layer interference, also not Affect lower layer production, oil well, water injection well all can use, can carry out the individual layer of oil well and join product, the test and Notes adopt that function is all strong, and cost is low, and the data that test is obtained is many, success rate height, accuracy height.
