Abstract
The utility model discloses a slim-hole mechanical water packing and plugging bridge-crossing oil well pump. The slim-hole mechanical water packing and plugging bridge-crossing oil well pump comprises an upper connector, an inner pump barrel, an outer pump barrel, an oil leaking device, a fixed valve assembly, a pressing connector and a lower connector, wherein the upper connector, the inner pump barrel, the oil leaking device, the fixed valve assembly and the pressing connector are arranged up and down in sequence and are connected by threads; the lower end of the upper connector is in threaded connection with the upper end of the outer pump barrel by outer threads; the upper end of the lower connector is in the threaded connection with the lower end of the outer pump barrel by outer threads; the inner pump barrel is suspended in the outer pump barrel; when a packer is pressurized and is sealed, a load acts on the outer pump barrel and the inner pump barrel does not bear a sealing force, so that the effect of protecting the inner pump barrel is realized. The designed outer diameter of a slim hole bridge-crossing pump is less than phi76mm by changing the structures and the coupling manner of the upper connector, the inner pump barrel, the outer pump barrel and the oil leaking device, so that the requirements of a layered mechanical water packing and plugging well in an oil well four-inch sleeve are met.
Description
Technical field
The utility model relates to a kind of oil extraction machinery and equipment, particularly relates to a kind of mechanical blocking water gap bridge oil well pump.
Background technique
At present, the mechanical blocking gap bridge pump using in petroleum production comprises outer tube, upper connection, interior pump barrel, lower contact, standing valve assembly, oil drainer mostly.Upper connection upper end connects outer tube by internal thread; pump barrel upper end in upper connection lower end connects by internal thread; scyewed joint is passed through in interior pump barrel lower end and oil drainer upper end; scyewed joint is passed through in oil drainer lower end and standing valve assembly upper end; thereby oil well pump is hung within the outer tube, and packet pressurizes when setting, and load is acted on outer tube; oil pump sleeve does not bear setting power, plays the effect of protection pump barrel.Be subject to pass a bridge the at present restriction of each modular construction of pump and connecting mode, common gap bridge oil well pump external diameter, more than Ф 107mm, can not be lowered to oil well pump in four cun of sleeve pipes, cannot meet the production requirement of layering machinery blocking water in four cun of sleeve pipes.
Model utility content
The purpose of this utility model is to provide a kind of slim-hole machinery blocking water gap bridge oil well pump that can meet layering machinery blocking water needs in four cun of sleeve pipes of oil well.
For achieving the above object, the utility model has adopted following technological scheme:
Slim-hole machinery blocking water gap bridge oil well pump, comprise upper connection, interior pump barrel, outer pump barrel, oil drainer, standing valve assembly, pressed joint, lower contact, it is characterized in that: described upper connection, interior pump barrel, oil drainer, standing valve assembly, pressed joint are setting up and down and pass through scyewed joint successively, described upper connection lower end is provided with outside thread, described upper connection lower end is by outside thread and outer pump barrel upper end scyewed joint, described lower contact upper end is provided with outside thread, and described lower contact upper end is by outside thread and outer pump barrel lower end scyewed joint.
Described interior pump barrel upper/lower terminal is equipped with outside thread, and described interior pump barrel upper end is by outside thread and described upper connection lower end scyewed joint.
Described oil drainer upper/lower terminal is equipped with internal thread, and described oil drainer upper end is by internal thread and described interior pump barrel lower end scyewed joint, and described oil drainer lower end is by internal thread and described standing valve assembly upper end scyewed joint.
The utility model adopts straight connection type structure that upper connection, interior pump barrel, outer pump barrel, oil drainer, standing valve assembly, pressed joint, lower contact are connected into an integral body; interior pump barrel is suspended in outer pump barrel; packet pressurizes when setting; load acts on outer pump barrel; interior pump barrel does not bear setting power, can play the effect of pump barrel in protection.By upper connection, interior pump barrel, outer pump barrel, the structure of oil drainer and the change of connecting mode, make slim-hole gap bridge pump design external diameter below Ф 76mm, thereby meet the needs of layering machinery blocking well in four cun of sleeve pipes of oil well.
Accompanying drawing explanation
Fig. 1 is an embodiment's of the utility model structural representation.
Embodiment
Embodiment of the present utility model: as shown in Figure 1, slim-hole machinery blocking water gap bridge oil well pump is comprised of upper connection 1, interior pump barrel 2, outer pump barrel 3, oil drainer 4, standing valve assembly 5, pressed joint 6, lower contact 7.Upper connection 1 upper end is provided with internal thread, can connect top oil pipe, in the lower end of upper connection 1 is provided with, outside thread, interior pump barrel 2 upper, lower two ends are provided with outside thread, oil drainer 4 upper, lower two ends are equipped with internal thread, upper connection 1 is by internal thread and interior pump barrel 2 screw-thread fit of lower end, upper connection 1 connects with outer pump barrel 3 by the outside thread of lower end, oil drainer 4, standing valve assembly 5, pressed joint 6 is setting up and down and pass through scyewed joint successively, lower contact 7 upper ends are provided with outside thread, with outer pump barrel 3 lower end scyewed joint, lower contact 7 lower ends are provided with internal thread, connect bottom oil pipe.
During work, by kits such as the utility model bottom oil pipe and mechanical blocking water packer, screen casing, plugs, with oil well pipe G.I.H.Tubing string puts in place, first qualified to the whole pressure testing of tubing string, above proposes rotation, transfers tubing string, by top oil pipe weight, be forced into the predetermined setting load of packet, complete packer set, by the water exit shutoff of oil reservoir top, production bottom oil reservoir, is then lowered to rod string and plunger.During pumping, packet bottom oil reservoir liquid enters in the oil pipe of oil well pump top by screen casing, packet, standing valve assembly and oil drainer, plunger successively, is pumped into surface line, thereby realizes the production of layering machinery blocking water in four cun of sleeve pipes.During packer set, compression load is delivered on outer pump barrel by upper connection, lower contact, and interior pump barrel does not stress, and avoids interior pump barrel to produce crooked, causes completion to produce asynchronous, has ensured the normal production after oil machinery blocking water.When next job execution, trip out after rod string, to throw bar oil drainer pin is thrown and opened, oily liquid in pipe leaks in sleeve pipe, has avoided environmental pollution, reduces operating worker labor intensity.
