Abstract
The utility model relates to an oil pump which is used for steam -injection and extraction of heavy oil and high pour-point oil, which is composed of a variable-diameter coupling, an outer sleeve, a pump cylinder, a coupling, a piston assembly, a connection cylinder and a fixed valve assembly, the upper and lower ends of the pump cylinder are respectively connected with the variable-diameter coupling and the connection cylinder by threads, the outer sleeve is arranged outside the upper part of the pump cylinder, the piston assembly is arranged in the pump cylinder and the connection cylinder, the fixed valve assembly is arranged at lower end of the piston assembly. The utility model adopts the structure of long piston and short pump cylinder, the oil pump has high efficiency and can seal or open steam-injection channel in the case of no adding operation times so as to realize the conversion of two work states: steam injection and oil extraction, thereby improving extraction effect and economy benefit of heavy oil and high pour-point oil.
Description
Technical field:
The utility model relates to a kind of viscous crude, height of being used for and coagulates the oil rig that oily steam injection is recovered the oil, and belongs to the oil recovery machiner class.
Background technique:
Viscous crude, the high oil that coagulates need to adopt technology modes such as steam injection or electric heating to be assisted because of its viscosity height, mobile poor to bringing great difficulty in its exploitation, could keep the oil well ordinary production.Yet viscous crude, the height of present field by using coagulates oily oil well pump need carry out underground work when realizing that notes are taken out conversion, and pump efficiency is lower, very unfavorable to oil well ordinary production and reduction cost for oil production.
The model utility content:
The purpose of this utility model is to provide a kind of can reduce the operation number of times and pump efficiency is higher, the high oil that coagulates of viscous crude that helps improving the oil extraction effect, reducing cost of winning is annotated vapour oil recovery dual-purpose oil well pump.
The utility model is to realize like this.This kind oil well pump is made up of sub-coupling, overcoat, pump barrel, box cupling, plunger piston assembly, connecting cylinder and standing valve assembly, and the pump barrel upper and lower end is connected with connecting cylinder with sub-coupling with box cupling with screw thread respectively, and the pump barrel upper outside is provided with overcoat; Be provided with plunger piston assembly in pump barrel and the connecting cylinder, the lower end is provided with the standing valve assembly.During work, the sub-coupling on this kind oil well pump top is connected with rod string with the downhole oil tubing string respectively with plunger piston assembly, predetermined position in the well, plunger can be with the notes vapour passage plugging on the pump barrel during normal the oil recovery, when annotating vapour, vapor pressure is opened and is annotated the vapour passage, can be under the situation that does not propose rod string and tubing string, directly annotate vapour, thereby reach the purpose that reduces viscosity of crude, reduces draw resistance.Simultaneously, the pump barrel outside installs overcoat additional, can prevent the injury of high-temperature steam to sleeve pipe, improves the reliability of oil pump tubular column work, prolongs the working life of oil well pump, reduces the operation number of times, reduces production costs.
The utility model has adopted long-plunger, short pump barrel structure, not only pump efficiency is high but also can annotate the vapour passage and can realize improving the transformation of annotating vapour and recovering the oil two kinds of working conditions the viscous crude height greatly and coagulate oily exploitation effect and economic benefit need not to increase under the situation of operation number of times by shutoff or open.
Description of drawings:
Accompanying drawing is an overall procedure structural representation of the present utility model.
Embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the utility model is made up of sub-coupling 1, overcoat 2, pump barrel 3, box cupling 4, plunger piston assembly 5, connecting cylinder 6 and standing valve assembly 7, its structure, assembled relation are as follows: pump barrel 3 upper and lower ends are connected with connecting cylinder 6 with sub-coupling 1 with box cupling 4 with screw thread respectively, and pump barrel 3 upper outside are provided with overcoat 2; Be provided with plunger piston assembly 5 in pump barrel 3 and the connecting cylinder 6, the lower end is provided with standing valve assembly 7.Wherein, sub-coupling 1 inside and outside disc lower end is respectively equipped with and connects pump barrel and apply mechanically internal thread and outside thread outward.Pump barrel 3 adopts the short pump barrel short than conventional pumps tube length degree, and its upper and lower end is respectively equipped with to be connected with connecting cylinder 6 with sub-coupling 1 uses screw thread, upper portion side wall to be provided with notes vapour passage 8.Plunger piston assembly 5 adopts the long long-plunger of length, and its inner chamber is provided with upper and lower valve and the ball seat of moving about.
