Abstract
The utility model provides an oil well pump capable of cleaning scaling automatically and belongs to an oil extraction device for oil fields. The oil well pump comprises a pump cylinder, a piston is arranged in the pump cylinder, a first valve ball is mounted on a first valve seat on the lower portion of the piston, a second valve ball is arranged on a second valve seat on the upper portion of the piston, a chemical storage box is arranged outside of the pump cylinder, an inner cavity of the chemical storage box is communicated with an inner cavity of a chemical outlet box under the piston through a chemical outlet on the pump cylinder, a chemical applying cylinder is arranged on the inner side of the chemical outlet box, a chemical delivery hole is arranged on the upper portion of the chemical delivery cylinder, a chemical hole corresponding to the chemical delivery hole is arranged on the inner side of the chemical outlet box, a spring is arranged between the upper portion of the chemical delivery cylinder and the upper surface of the chemical outlet box, a third valve seat is arranged in the pump cylinder under the chemical delivery cylinder, and a third valve ball is mounted on the third valve seat. According to the oil well pump, descaled chemical can be delivered into the pump cylinder directly, the release rate is slow, the validity period is long, the descaling effect is good, and normal production of oil extraction is guaranteed. The oil well pump is reasonable in structure and reliable to use.
Description
Technical field
The utility model provides a kind of oil extraction in oil field device.
Background technique
Along with the deep development in oil field, the scale formation in the oil well is on the rise, and the encrustation of oil pipe, sleeve pipe is especially outstanding.In the oil pumping production process, the dirty sector-meeting that splits away off deposits in the standing valve below piston along with oil flows to into pump barrel, and the time has been grown and can cause the standing valve dirt stifled or setting not tight, forms pump and leaks, and causes oil well not fuel-displaced.Present descaler has slowly-releasing scale inhibition pipe, and solid corrosion inhibitor is equipped with in its inside, because corrosion inhibitor discharges comparatively fast, effective date is shorter, and descale effect is relatively poor.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of oil well pump from settling accounts dirt, to improve descale effect.
The utility model is to realize like this, a kind of oil well pump from settling accounts dirt, it has pump barrel, piston is installed in the pump barrel, on the first valve seat of piston bottom the first valve ball is installed, above second valve seat on piston top the second valve ball is installed, in described pump barrel outside storage medicine-chest body is arranged, storage medicine-chest intracoelomic cavity is by the medicine outlet hole on the pump barrel, be connected together with the inner chamber of the drug casing of piston below, the drug box inside has the dispenser cylindrical shell, the dispenser hole is arranged at dispenser cylindrical shell top, and the drug box inside has the medicine hole corresponding with the dispenser hole, between dispenser cylindrical shell top and the drug casing upper surface spring is arranged, in the pump barrel of dispenser cylindrical shell below the 3rd valve seat is arranged, the 3rd valve ball is installed on the 3rd valve seat.
Adopt the oil well pump of said structure, the scale removal medicament is directly sent in the pump barrel, and release rate is slow, and effective date is long, and features high scale-removing effect has guaranteed the normal production of recovering the oil.And rational in infrastructure, use reliable.
Description of drawings
Fig. 1 is the schematic representation of the utility model structure.
Fig. 2 is the A-A sectional drawing of Fig. 1.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing further specifies the utility model.
As shown in drawings, a kind of oil well pump from settling accounts dirt of the utility model, it has pump barrel 12, piston 11 is installed in the pump barrel, on the first valve seat 9 of piston bottom the first valve ball 10 is installed, above second valve seat 14 on piston top the second valve ball 15 is installed, it is characterized in that, in described pump barrel outside storage medicine-chest body 13 is arranged, storage medicine-chest intracoelomic cavity is by the medicine outlet hole 3 on the pump barrel, be connected together with the inner chamber of the drug casing 5 of piston below, the drug box inside has dispenser cylindrical shell 8, and dispenser hole 7 is arranged at dispenser cylindrical shell top, the drug box inside has the medicine hole 4 corresponding with the dispenser hole, between dispenser cylindrical shell top and the drug casing upper surface spring 6 is arranged, have on the 3rd valve seat 1, the three valve seat in the pump barrel of dispenser cylindrical shell below the 3rd valve ball 2 is installed.
There is certain spacing the starting stage of recovering the oil between pump barrel and the dispenser cylindrical shell, and the fouling situation is yet not serious.At this moment, medicine hole 4 is sealed by the dispenser cylinder body outer wall, and the scale removal medicament can not flow out.When using a period of time, standing valve suitably lengthens the length of sucker rod 16 when namely the valve that consists of of the 3rd valve seat, the 3rd valve ball has fouling, so that piston falls to when minimum, can depress the dispenser cylindrical shell, aligns with the dispenser hole in the medicine hole.The scale removal medicine enters in the dispenser cylindrical shell, enters in the pump barrel again, and the valve ball of standing valve and surface of contact and the pump barrel inwall of valve seat are carried out scale removal.When piston rises, break away from the dispenser cylindrical shell, the dispenser cylindrical shell rises under the effect of spring, sealing medicine hole.Therefore, the scale removal medicament only flows out a less part at every turn, and release rate is slower.
Described drug box inside has the medicine hole 4 corresponding with the dispenser hole, refers to the position that can align with the dispenser hole after the medicine hole is in the dispenser cylindrical shell and depresses.
