Abstract
This invention uses suspender in substitution of oil-pipe suspending and supporting the oil pump on oil-layer casing, uses hollow sucker rod to drive oil pump and as oil outflow passage, and the plunger passage of oil pump is directly connected witht he hollow sucker rod to pump oil. Tis device consists of suspender having expansion block and connected with sucker rod, connector pipe and oil pump barrel as well as sucker rod and plunger having lower ends connected, and righting aid having two ends screw-connected with pump barrel and screen pipe respectively. It has such advantages as high pump efficiency, low cost, energy saving, and convenient management.
Description
The present invention relates to a kind of oil production method and equipment that oil pipe hangs oil well pump that do not have, be applicable to well recovery.
In the producing well in oil field, the oil well pump oil production method accounts for about 85%, this method is furnished with oil pumper on ground, oil pipe is arranged in well, sucker rod and oil well pump, wherein the effect of oil pipe is to hang and supporting oil well pump and as fuel-displaced runner, and the existence of oil pipe has increased the oil well cost, increased workman's oil well workload, complicated casing programme and increase borehole size has increased drilling cost etc.
The object of the present invention is to provide a kind of raising oil well pump pump efficiency, reduce labor strength, reduce cost energy-conservation Oilpipe free suspension pump extracting method and device.
Realize that the technical measures that the present invention taked are: 1. adopt hanger give allocation replace oil pipe with the oil well pump hanger bearing on the oil reservoir pipe; 2. adopt hollow rod to drive oil well pump, with hollow rod as fuel-displaced runner; 3. the oil pump plunger piston runner directly is communicated with hollow rod and recovers the oil.
Fig. 1 is a general structure schematic diagram of the present invention, and Fig. 2 is a claw hanger structural representation, and Fig. 2 a is the A-A sectional view of Fig. 2, and Fig. 3 is upper and lower slips hanger structural representation.
In conjunction with the accompanying drawings the present invention and embodiment are described as follows:
Hollow rod is that the hollow section of 2～n joint is threaded by two male threads or male and female and forms; Fig. 2 and Fig. 3 show two embodiment of hanger; The two ends of centralizer 9 are threaded with pump barrel 8, screen casing 10 respectively;
Being constructed as follows of claw hanger shown in Figure 2: the sucker rod special joint 5 that is threaded with hollow rod 4
2Radially uniform 2 to 4 finger 5g are corresponding to it rotary sleeve 5
3In 2 to 4 grooves are arranged, the angle that staggers has 2 to 4 elongated slots vertically on the rotary sleeve inwall, have translot to be communicated with rotary sleeve 5 respectively between groove and elongated slot
3On be fixed with 2 to 4 shifting blocks 5
0, its garden cambered surface is fixed on body 5 with axle
1On claw 5
4Match, be wound with torsion spring on the claw axle, with body 5
1What be connected has a connecting tube 6 that is threaded with pump barrel 8, and 5e is the spline piece that prevents the body rotation.When rotary sleeve 5
3When being rotated counterclockwise, the shifting block 5 on it
0Get out of the way claw 5
4, under the effect of torsion spring restoring force, claw 5
4Open and be stuck on the production string wall 3, when rotary sleeve 5
3When turning clockwise, the shifting block 5 on it
0Claw is drawn in, hanger 5 and oil pumping pump barrel 8 can be mentioned ground together.
Being constructed as follows of following, lower slips hanger shown in Figure 3: the last swivel joint 5a that is connected with hollow rod, the garden face is the conical surface outside its underpart, the external screw thread of end is connected with lower contact 5b, 5e is the spline piece that prevents that lower contact 5b from rotating, when removing oil well pump, upper and lower slips 5c and 5d are in two joint minimum diameter places, and hanger can pass through in down-hole casing smoothly; When oil well pump descended to the needs permanent position, by sucker rod 4 rotations, last swivel joint 5a was with respect to the descending compression spring of the lower contact 5b 5f that does not rotate, force upper and lower slips 5c, 5d outwards enlarges and is stuck on the production string, finishes the suspension of oil well pump, can start oil pumping machine oil pumping.So long as sucker rod can make the flexible piece of hanger stretch out when a direction rotation, and when rotating, other direction can make the structure of the flexible piece withdrawal of hanger all belong to this patent protection domain.
Advantage of the present invention is: without oil pipe, reduce the oil well investment 1.; 2. change fuel-displaced runner, reduce sand card, sand plug, prolong the service life of pump detection period and pump; 3. reduce plunger and pump barrel gap oil leakage, can improve pump efficiency 10～20%; 4. change the oil pumper stress condition, it is fuel-displaced to become down stroke, alleviates pumping unit load, economizing on energy and electricity; 5. adopt the direct circulation pump, finish the oil well direct flushing, simplify technology for washing well, alleviate labor strength, reduce production costs; 6. the simplification casing programme is beneficial to slimhole drilling, reduces drilling cost.
