Abstract
The utility model discloses a kind of jet pump termination of pumping instant shut-in pressure valve, comprise: be positioned at the power fluid import in lower contact, formation fluid tubular conduit, pressure transmission passage is provided with and with not connected at formation fluid tubular conduit inwall, outside formation fluid tubular conduit, cover has return spring, the formation fluid tubular conduit other end connects sealing sliding sleeve by connector, sealing sliding sleeve is provided with formation fluid inlet, formation fluid inlet outside is provided with switching sliding sleeve, lower contact is also provided with lateral opening and is connected with pressure transmission passage under pressure.The beneficial effects of the utility model are: immediately measure stratum after stopping row and recover data, reduce the impact of well bore storage effect, accelerate the appearance of radial flow, fast reaction formation characteristics, need not downhole testing tool operation; Oil pipe and steel wire salvaging operation are avoided; New technology mode is provided to understanding stratum; Improve formation testing efficiency, reduce formation testing operation, reduce formation testing cost.
Description
Technical field
The utility model relates to a kind of Oilfield Natural Gas Plant production technique field, particularly relates to a kind of downhole jet pump termination of pumping instant shut-in pressure valve of Gas Exploitation.
Background technology
Conventional fluidic pump discharge opeing construction technology, because pump does not design on-off valve device in the heart, therefore can only measure the flowing pressure between pump waiting, and is difficult to obtain strata pressure recovery data directly, in time.
Summary of the invention
Technical problem to be solved in the utility model is to provide one and utilizes jet pump fluid-discharge technology to realize downhole closing, obtains the downhole jet pump termination of pumping instant shut-in pressure valve that strata pressure recovers data.
The technical scheme that the utility model adopts is: a kind of jet pump termination of pumping instant shut-in pressure valve, this pressure valve spool comprises: be positioned at the power fluid import in lower contact, the formation fluid tubular conduit be tightly connected by sealing ring with lower contact, pressure transmission passage is provided with and with not connected at described formation fluid tubular conduit inwall, outside described formation fluid tubular conduit, cover has return spring, the described formation fluid tubular conduit other end connects sealing sliding sleeve by connector, described return spring is between lower contact and connector, described sealing sliding sleeve is provided with formation fluid inlet, switching sliding sleeve is provided with in described formation fluid inlet outside, described lower contact is also provided with lateral opening and is connected with pressure transmission passage under pressure.
The beneficial effects of the utility model are: after 1, stopping row, immediately measure stratum and recover data, centre does not have interval time, and, owing to being downhole closing, substantially reduce the impact of well bore storage effect, accelerate the appearance of radial flow, be conducive to the fast reaction of formation characteristics, for mesolow nonflowing well successful.2, in whole discharge opeing process, ask product, pressure buildup test need not downhole testing tool operation; 3, complete stream pressure and pressure recovery data remove pump core by waterpower, take pressure gauge out of ground and obtain pressure data, avoided oil pipe and steel wire salvaging operation; 4, the development of this pressure valve is perfect further jet pump fluid-discharge technology, to realize after discharge opeing moment downhole closing, obtains downhole closing pressure recover data after discharge opeing, provides a set of new technology mode to understanding stratum further; 5, adopt this kind of discharge opeing closing well mode, part well can replace dst technology; 6, after this kind of draining mode is promoted, traditional oil testing tech can be changed, improve formation testing efficiency fast and effectively, reduce formation testing operation, reduce formation testing cost, promote formation testing industry development greatly.
Accompanying drawing explanation
Fig. 1 is jet pump termination of pumping instant shut-in pressure valve schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, a kind of jet pump termination of pumping instant shut-in pressure valve, this pressure valve spool comprises: be positioned at the power fluid import 1 in lower contact 2, the formation fluid tubular conduit 9 be tightly connected by sealing ring 7 with lower contact 2, pressure transmission passage 4 is provided with and with not connected at described formation fluid tubular conduit 9 inwall, outside described formation fluid tubular conduit 9, cover has return spring 8, described formation fluid tubular conduit 9 other end connects sealing sliding sleeve 11 by connector 5, described return spring 8 is between lower contact 2 and connector 5, described sealing sliding sleeve 11 is provided with formation fluid inlet 6, switching sliding sleeve 10 is provided with in described formation fluid inlet 6 outside, described lower contact 2 is also provided with lateral opening 3 and be connected with pressure transmission passage 4 under pressure (depending on not going out in figure), the aperture entry place of lateral opening 3 and described power fluid import 1 are in the same liquid flowing space.Power fluid is injected liquid by pump mouth to power fluid import 1 and is formed subnormal ambient, and liquid also flows into through lateral opening 3 and under pressure pressure transmission passage 4 promotes spring and open switching sliding sleeve 10, when stopping operation, switching sliding sleeve 10 returns under the effect of return spring 8 closes formation fluid inlet 6.
The course of work of jet pump termination of pumping instant shut-in pressure valve: the pump heart with jet pump termination of pumping instant shut-in pressure valve is dropped into down-hole together with electronic pressure gauge in oil pipe, free-falling or be pumped into position locking, when going into the well, pressure valve is in closed condition.Utilize injection pump annular space to suppress the discharge opeing of 10-20Mpa reacting cycle, when pressure transmission hole pressure exceedes liquid column hydrostatic pressure 3.1Mpa, switch valve is opened, and formation fluid is sucked by jet pump and discharges ground; After hydraulic pump quits work, switching sliding sleeve is closed under the effect of return spring, stops waiting 1-2 days, measures strata pressure and recovers data.Open pump heart locking device, the backwashing pump heart to well head, playback strata pressure recovery curve.
