Working condition of the present utility model is, with a kind of oil well heat of the utility model wash exempt to pollute give up that packing device is connected to the oil well pump flow string be lowered into precalculated position in the well with flow string bottom, with the degree of depth adjust suitable after, under the tubing string after the projected depth upper lifting pipe post certain altitude, sliding pin 4-8 in this moment righting changement 4 has realized that short track from the orbit centre pipe 4-1 lateral wall is to the conversion of long track, when transferring tubing string, top cover 4-2 in the righting changement 4 promotes the up and Compress Spring 3-6 of cover 3-8 that blocks in the slips supporting mechanism 3, when the position at the second interior cannelure 4-2a of top cover 4-2 and lock ball 3-9 place to timing, lock ball 3-9 skids off from the second cannelure 4-1a on the orbit centre pipe 4-1 and enters the second interior cannelure 4-2a, slips supporting mechanism 3 is unlocked, therefore righting changement 4 promotes sheath 3-5, slips support 3-4 and slips 3-3 are up, slips 3-3 is strutted by wedge 3-2 and stings on internal surface of sleeve pipe, continue again to press down tubing string to certain load, setting shear pin 1-4 is cut off, machinery is lost and is dragged for mechanism's 1 descending and automatic reverse, when transferring after tubing string load reaches designing requirement, slow upper lifting pipe post, this moment machinery is lost and is dragged for mechanism 1 and realize giving up losing to have separated with sealing drainage mechanism 2 under the cooperation phorogenesis of dragging for track body 1-5 and track pin 2-2, hangs the position and gets final product the completion production of pumping carrying certain distance to oil pumping pump on the tubing string after tubing string is given up.Stratum liquid up enters in the upper sleeve of the sealing drainage 2 self-styled leather cup assembly 2-3 of mechanism by the ball seat 5-3 in the one-way valve mechanism 5 and steel ball 5-2 during normal production, then is evacuated to endlessly ground by oil well pump.
When oil well paraffinication need to be carried out hot-washing wax remover, ground pumps into hot water from oil sets annular space, hot water drops to the utility model along sleeve pipe---and oil well heat is washed and is exempted to pollute when giving up packing device the self-styled leather cup assembly in the sealed drainage mechanism 2 and the steel ball 5-2 in the one-way valve mechanism 5 and block and can not pour in down a chimney into oil reservoir, can only enter oil pipe by oil well pump and return ground, thereby avoid pouring in down a chimney the problem that the oil reservoir impact is produced that enters because of the hot wash liq of oil well.
When needs trip out the utility model, only need transfer the lengthening flow string, when tubing string bottom during near top of fish, the machinery of slowly transferring tubing string bottom tubing string this moment is lost and is dragged for losing in the mechanism 1 and drag for track body 1-5 and can automatically enter sealing drainage mechanism 2, after pressing down tubing string load 0.5-1.0t, the some circles of clockwise direction rotation tubing string afterwards slow upper lifting pipe post track pin 2-2 this moment can enter in the salvaging rail groove automatically, continuing the upper lifting pipe post cuts off deblocking shear pin 2-7 first, track pin 2-2 drives the up leakage opening 2-8a that abdicates of sealing slip pipe 2-4, liquid in the above sleeve pipe of self-styled leather cup assembly 2-3 this moment will flow into the shaft bottom by leakage opening 2-8a, the frictional force that has caused because of the swollen self-styled leather cup assembly 2-3 of liquid when having reduced pipe; Continue the upper lifting pipe post and go upward to the second cannelure 4-1a and lock ball 3-9 position to timing as orbit centre pipe 4-1, lock ball 3-9 skids off from the second interior cannelure 4-2a and enters in the second cannelure 4-1a, slips 3-3 regains under the effect that lifts of wedge 3-2, block and overlap 3-8 resilience under the effect of spring 3-7, with slips supporting mechanism 3 position and locks, the righting changement is descending, and so far the utility model can be realized complete deblocking.
The utility model novel structure is unique, result of use is good, can effectively solve one-trip string and finish being lowered to, setting, giving up of instrument, then upper lifting pipe post direct all programs such as completion production to the pump setting depth, can also utilize the realization of this time tubing string to the salvaging function of Back-off Pipe String when needing, greatly simplify construction link, had good economic and social benefit.
