Description
Technical field
The present invention is the laminated distributor under well oil tool of oil field oil recovery usefulness, particularly a kind of releasing packer well-washing device.
Background technology
Implement layering card water blockoff oil recovery technique, envelope is fallen high aquifer, is the effective way that the control well water rises.Layering card water blockoff will adopt packer, and existing packer kind is more, but has that easy inefficacy, downslide, supporting capacity are low, the construction success rate is low and problem such as deblocking difficulty.It is to be brought it into by oil pipe to suppress the seat envelope behind the oil reservoir position that there is one type packer at the scene, and then oil pipe is separated with packer, realizes that this process scene is called to give up; Such packer is in order to adapt to hydraulic base sealed requirement, and the tubing string of it and its bottom is airtight, and inner liquid can not come out; Outside liquid can not be entered, and therefore, can not carry out clean-out service to tubing string after the following completion; Cause the foreign material blocking channel in the tubing string; Make the pressure transmission less than on the piston, can not accomplish the action that needs, packer can not the seat envelope.
Summary of the invention
The objective of the invention is to design a kind of releasing packer well-washing device, can carry out well-flushing to tubing string, the seat envelope is reliable, realizes oil production by layer.
The objective of the invention is to realize like this: back-off packer, seat envelope valve ball, seat blocking seat are arranged, and seat blocking seat is installed in the back-off packer, also has tube connector, guide way, well-flushing ball-and-seat, shunting joint; The well-flushing ball-and-seat is installed on the joint of shunting, and the perpendicular shape passage in left side, radial passage, the perpendicular passage in right side are arranged on the joint of shunting, well-flushing ball-and-seat inlet and the perpendicular unidirectional UNICOM of shape passage in left side; The perpendicular shape passage in left side communicates with the radial passage, and circular arc, UNICOM's groove, eccentric channel are arranged on the guide way, and UNICOM's groove communicates with eccentric channel; The guide way upper end is a conical entrance, and eccentric channel on the guide way and conical entrance intersect, and the circular arc on the guide way is buckled on the well-flushing ball-and-seat outer wall; Tube connector entangles guide way, and guide way can not be rotated, and the perpendicular passage in eccentric channel and right side is relative all the time; UNICOM's groove is on the well-flushing ball-and-seat, and the tube connector bottom is connected with joint top, shunting major thread, and joint bottom, shunting is connected with back-off packer; Tube connector top is connected with oil pipe, during well-flushing, in sleeve pipe, squeezes into flushing fluid; Flushing fluid through the radial passage, the perpendicular shape passage in left side, well-flushing ball-and-seat, UNICOM's groove, eccentric channel get into upwards to flow out and wash away foreign material, during the seat envelope, in oil pipe, drops into the seat envelope valve ball of diameter less than eccentric channel, the perpendicular passage in right side; Seat envelope valve ball is directed to body upper end conical entrance introducing eccentric channel, the perpendicular channel seat in right side drops on the port of blocking seat, in oil pipe, suppresses, and the well-flushing ball-and-seat is closed; Oil pipe is in air-tight state, and pressure raises, back-off packer seat envelope.
The invention has the beneficial effects as follows: the well-flushing ball-and-seat is in eccentric position, and the diameter that can make the right side erect passage, eccentric channel increases, and in the well of casing diameter commonly used, can design the perpendicular passage in right side, eccentric channel that back-off packer seat envelope valve ball is passed through; The perpendicular passage in eccentric channel and right side is relative all the time, and the requirement of back-off packer seat envelope can be satisfied in the back-off packer seat envelope valve ball position that can accurately fall; Can carry out reverse well-flushing to the oil pipe on the packer before the seat envelope; Can the foreign material in the oil pipe be washed away, guarantee that the seat seal pressure is delivered on the packer, but packer can seal by seat; Make oil well successfully realize oil production by layer, have remarkable economic efficiency.
