Abstract
The invention discloses a connected dissociator of downhole tool, which is characterized by the following: delivering joint, underbodies, downhole tool, mandrel, connected rod; extending the underbodies with cutting each round root in the course of upper body insert into underbodies; inserting the upper body into the underbodies; recovering the underbodies; suspended-connecting the upper body and the underbodies to one body; bringing the upper body, lower body and the downhole tool to work together with the connected rod; bringing the upper body, underbodies and the downhole tool upgo with the connected rod; touching cone in the inner surface of the underbodies end and the cone on the lower of the delivering joint; generating tension; extending the underbodies with the cutting round toot; losing suspend of the upper body; separating the upper body and the underbodies; submitting all tools above the upper body. This invention possesses high intensity, simple structure and simple operation.
Description
One, technical field
The invention belongs to the oil well downhole tool, is a kind of downhole tool connecting separator.
Two, background technology
Oil well pump on the oil field when piston diameter greater than pump on during pipe aperture, need to adopt connection that on-off connector could realize sucker rod and oil well pump piston and separate.The on-off connector kind is more, all comes with some shortcomings, and as patent No. 96227867.x, though can improve supporting capacity and working life, but its complex structure, the processing cost height connects, separates dumb.
Three, summary of the invention
The purpose of this invention is to provide a kind of intensity height, simple in structure, difficulty of processing is little, the service-strong downhole tool connecting separator.
The object of the present invention is achieved like this: by releasing-joint, the upper body, lower body is formed, the upper body is on lower body, the bottom, upper body is in lower body, the upper body is connected with the lower body suspension type, suspension place is the annular plane, the internal diameter of the epimere lower body at the place, annular plane of suspension place is less than the internal diameter of hypomere lower body, the external diameter of the epimere upper body at the place, annular plane of suspension place is less than the external diameter of hypomere upper body, the cutting of lower body top is split into polylith bar body, bar body root is under the annular plane of suspension place, releasing-joint is in the upper body, on the lower body, lower body upper port internal diameter is greater than releasing-joint lower surface external diameter.Releasing-joint is connected with seating nipple top, and the connecting rod bottom is connected with the upper body, and lower body is connected with downhole tool.
The invention has the beneficial effects as follows: the axial force during owing to work is vertical with the annular plane at upper body, following body overhang place, lower body is cut each bar body of holding and can expand outwardly around root during work, so use reliable, the intensity height, simple in structure, difficulty of processing is little, and connection, convenient separation are simple to operate.
Four, description of drawings
Fig. 1 is the assembling drawing of the embodiment of the invention.
Fig. 2 is the sectional view that lower body top is cut the slivering body region in the embodiment of the invention.
Five, the specific embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is described.
Among the figure: the 1st, releasing-joint, the 2nd, connecting rod, the 3rd, upper body, the 4th, lower body, the 5th, downhole tool, the 6th, seating nipple.Be that embodiments of the invention are by releasing-joint 1, connecting rod 2, upper body 3, lower body 4, downhole tool 5, seating nipple 6 is formed, upper body 3 is on lower body 4,3 bottoms, upper body are in lower body 4, upper body 3 is connected with lower body 4 suspension types, suspension place is the annular plane, the angle of annular plane and vertical axis is 85 °～95 °, the internal diameter of the epimere lower body 4 at the place, annular plane of suspension place is less than the internal diameter of hypomere lower body 4, the external diameter of the epimere upper body 3 at the place, annular plane of suspension place is less than the external diameter of hypomere upper body 3, the cutting of lower body 4 tops is split into polylith bar body, bar body root is under the annular plane of suspension place, releasing-joint 1 is in upper body 3, on the lower body 4, lower body 4 upper port internal diameters are greater than releasing-joint 1 lower surface external diameter.Lower body 4 upper inside surface are taper, and tapered diameter is up big and down small, and releasing-joint 1 lower external face is conical, and the taper seat diameter is up big and down small.Releasing-joint 1 is connected with seating nipple 6 tops, and connecting rod 2 bottoms are connected with upper body 3, and lower body 4 is connected with downhole tool 5.
During use, releasing-joint 1, lower body 4, downhole tool 5, seating nipple 6 first G.I.Hs, connecting rod 2, upper body 3 is lowered to again, in the process that insert in the lower body 4 upper body 3, each bar body that lower body 4 is cut out expands outwardly around root, insert in the lower body 4 upper body 3, each bar body that lower body 4 is cut out is inwardly regained reinstatement around root again, upper body 3 and lower body 4 suspension types are linked into an integrated entity, connecting rod 2 just can drive upper body 3, lower body 4, downhole tool 5 is worked together, because the axial force during work is vertical substantially with the annular plane of upper body 3 lower bodies, 4 suspensions place, lower body 4 is cut each bar body of holding and can expand outwardly around root during work, so use reliably, the upper body 3 during work, lower body 4, downhole tool 5 moves under releasing-joint 1.
During operation, it is up that connecting rod 2 drives upper bodies 3, lower body 4, downhole tool 5, when the taper of lower body 4 port inner surfaces contacts with releasing-joint 1 lower external face taper seat, produce tension force, each bar body that lower body 4 is cut out expands outwardly around root, loses the suspension to upper body 3, and separate with lower body 4 upper body 3, instrument on the upper body 3 can all propose, and oil well can carry out the bottom operation.
After upper body 3 enters in the lower body 4,, can add an adjusting device at the place, location for reducing end play by the location, bottom of upper body 3.
