Described ball-and-seat comprises holddown spring, support, steel ball and ball seat, described holddown spring one end withstands on inner core inward flange, the other end withstands on support, described support can slide up and down to be arranged on inner core inside, described internal stent hollow is also connected with the endoporus of top connection with sampling storehouse, and this support outer wall circumference is also formed with multiple through hole for discharge opeing, described ball seat and inner core inner wall sealing affixed, described steel ball is arranged between support and ball seat, can realize the logical of ball-and-seat close by the cooperation of steel ball and ball seat.
The invention has the beneficial effects as follows:
1, sampling accurately.Sampling storehouse is unique liquid passage excessively, and sample is one section of intercepting completed in production fluid flow process, truly can reflect stratum fluid oil-water ratio.2, tetrad can be arranged at pump to do to apply in oil test operation.3, this jet pump sampler has locking mechanism, when running into strong collision, can not cause the leakage of sample.
Accompanying drawing explanation
Fig. 1 is the structural representation of jet pump sampler of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
See Fig. 1, jet pump sampler of the present invention comprises the top connection 1 be tightly connected successively, urceolus 8, fall to press mandrel 9, flowing mandrel 13, duckbilled 14, holder cylinder 15 and plug 16, described urceolus 8 inside is provided with inner core 7, this inner core 7 inside is provided with the ball-and-seat that only allows discharge opeing earthward, described pressure mandrel 9 inside is formed with sampling storehouse, the pressure mandrel 9 that should fall is provided with and the setting-out plug 17 sampling storehouse and be connected, and should fall pressure mandrel 9 on also cover have a back-moving spring 10, described back-moving spring 10 one end withstands on down on the flange of pressure mandrel 9, the other end withstands on the end of a power sub 11, described power sub 11 be enclosed within flowing mandrel 13 on and the other end of this power sub 11 withstand under the effect of back-moving spring 10 flowing mandrel 13 flange on, described power sub 11 is also sealedly connected with a switching sliding sleeve 12, described switching sliding sleeve 12 is enclosed within flowing mandrel 13, described flowing mandrel 13 is provided with multiple inlet opening be connected with sampling storehouse, each the logical of described inlet opening can be controlled close by sliding up and down of switching sliding sleeve 12.Described ball-and-seat comprises holddown spring 3, support 4, steel ball 6 and ball seat 5, described holddown spring 3 one end withstands on inner core 7 inward flange, the other end withstands on support 4, it is inner that described support 4 can slide up and down to be arranged on inner core 7, described support 4 inner hollow is also connected with the endoporus of top connection 1 with sampling storehouse, and this support 4 outer wall circumference is also formed with multiple through hole for discharge opeing, described ball seat 5 is affixed with inner core 7 inner wall sealing, described steel ball 6 is arranged between support 4 and ball seat 5, can realize the logical of ball-and-seat close by the cooperation of steel ball 6 and ball seat 5.All sealing is realized by joint ring 2 between each parts that jet pump sampler of the present invention is connected.
Jet pump sampler of the present invention is a sealing device, and sampling storehouse is unique liquid flow path, and institute's sample thief is the formation sample that discharge opeing terminates final flowing, true and reliable, correctly can reflect the original physical property on stratum.Due to the particularity of jet pump discharge opeing sampling craft, meet the analytical effect of formation physical property, utilize the switch valve bottom the pump heart (switch valve is made up of back-moving spring 10, power sub 11, switching sliding sleeve 12 and flowing mandrel 13), upper design adds sampling storehouse and ball-and-seat forms trap space.When discharge opeing, bottom switch valve is opened, and ball-and-seat is opened under jet pump swabbing action, and formation fluid enters along switch valve, is sucked discharge ground by sampling storehouse to ball-and-seat by jet pump.When stopping discharge opeing, bottom switch valve and top ball-and-seat are closed simultaneously, and the formation sample that discharge opeing terminates final period flows in sampling storehouse, is completed sampling by trap.
Concrete sampling process is as follows:
The pump heart with jet pump sampler is dropped into down-hole together in oil pipe, free-falling or be pumped into position locking (when going into the well, switch valve and ball-and-seat are in closed condition simultaneously).Injection pump annular space is utilized 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, ball-and-seat is under the swabbing action of jet pump simultaneously, formation fluid upwards pushes steel ball open, flow channel is opened, formation fluid enters along the inlet opening in switch valve, is sucked discharge ground by sampling storehouse to ball-and-seat by jet pump; After hydraulic pump quits work, switching sliding sleeve is closed under the effect of back-moving spring 10, and steel ball 6 also seals under the effect of upper end holddown spring 3 and between ball seat 5, thus formation fluid trap in sampling storehouse.Open pump heart locking device, the backwashing pump heart, to well head, takes out jet pump sampler and releases sample from setting-out plug 17.
In sum, content of the present invention is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present invention, but these embodiments all comprise within the scope of the present invention.
