Field ground surface works》Periodical literature on delivered the paper document of entitled " gas well swabbing pumping equipment ", the document is mainly public
The technological principle of pumping pumping equipment is opened：With ground fishing-vehicle as power, by steel wire rope, using high strength tubing swab handle
Hydrops bailing from oil pipe is discharged, and is reduced the back pressure that fluid column is produced to gas-bearing formation, is made gas well return to normal production.Fishing-vehicle passes through steel
Cord will arrive certain depth under swab, it is then rapid on put and put for several times that (concrete number of times can be according to fishing-vehicle power and steel wire rope
Load determine), the hydrops in pit shaft is pumped in oil pipe, and makes the liquid level of liquid level in oil pipe higher than oil jacket annular space.So
Swab is above carried afterwards to well head, liquid more than swab in oil pipe can be extracted out oil pipe, and in making pit shaft, liquid-column height declines.Weigh according to this
Pumping is carried out again until gas well returns to normal production.The technique can be applicable to the well caused by the regular discharge opeing of hydrops well, clear salt
Cylinder liquid level rise, due to the working systems such as foaming water discharge adjustment cause not in time water column by well kill and closing well after recover raw again
Periodicity huge discharge draining is carried out before product.
Existing common pumping technique locomotivity with above-mentioned periodical literature as representative is stronger, but by tensile strength of wire,
The restriction of the conditions such as dynamic sealing ability, it is difficult to reach the safe and efficient pumping discharge opeing to high pressure and deep well.
