Abstract
The utility model relates to a proportion adjustment pump of ternary injection and polymer injection for an oil field. An adjustment rod and a seal sleeve are arranged in a pump head. A variable volume hole is arranged on the adjustment rod, the seal sleeve and the adjustment rod are sealed through gaps, and the position of the adjustment rod is changed through thread transmission. The variable volume hole is composed of two regular parts, the left side is a semi-circle, and the right side is in an isosceles triangle shape with the diameter of the semi-circle as the bottom edge. The proportion adjustment pump of ternary injection and polymer injection for the oil field has the advantages that relative position of the variable volume hole relative to a plunger is changed by the adjustment rod, and accordingly effective travel distance of the pump is set and an adjustment function of pumping flow is achieved. The variable volume hole on the adjustment rod can prevent the plunger from generating vibration and noise when the plunger crosses the variable volume hole. The proportion adjustment pump of ternary injection and polymer injection for the oil field is compact in structure and low in cost, can achieve single injection of a single cylinder, omits a frequency conversion device, and thoroughly overcomes defects existing in the technology of single pump and single well and single pump and multiple wells.
Description
Technical field
The utility model relates to the oil field and regulates pump with the ratio that ternary is injected and polymer injects, and belongs to the oil field and uses equipment technical field.
Background technique
Along with the oil field gets into the late high water content period exploitation, be that the tertiary oil recovery technology of representative becomes the important technical that improves oil recovery factor, continues the prolongation oilfield stable production phase to annotate ternary and the polymer injection displacement of reservoir oil.Ternary injection pump and polymer injection pump have been produced thereupon; The well number that injects according to every pump successively is divided into single pump individual well and many wells of pump technology again; Because adopt traditional reciprocating pump not to be with Flow-rate adjustment, so above two kinds of pumps that technology adopted must adopt converter plant, it is big that the pump of this pattern exists floor space; Capital construction investment is big; Easily damaged parts quantity is many, and operation cost high (for single pump individual well) and the accessory (distributing valve) that adopts produce bigger viscosity reduction to polymer, the big defectives such as (for the many wells of a pump) of whole system control difficulty.
Summary of the invention
Defective in view of the prior art existence; The purpose of the utility model provides a kind of simple for structure; Cost is low, and can realize that converter plant is annotated, omitted to the single cylinder list, pump is regulated with the ratio that ternary is injected and polymer injects in the oil field that thoroughly overcomes single pump individual well and the existing disadvantage of many wells of pump technology.
For realizing above-mentioned purpose; The technological scheme that the utility model adopted is: pump is regulated with the ratio that ternary is injected and polymer injects in the oil field; An adjustable lever and a stuffing box gland are set in pump head; The transfiguration hole is set on the adjustable lever, and stuffing box gland and adjustable lever seal through the gap, and change the position of adjustable lever through the screw thread transmission.
Said transfiguration hole is made up of two rule parts, and the left side is a semicircle, and the right side is for being the isoceles triangle shape on base with the semicircle diameter.
The beneficial effect of the utility model is: adjustable lever changes the relative position of transfiguration hole with respect to plunger, thereby sets the effective travel size of pump, realizes the regulatory function of pump duty; Transfiguration hole on the adjustable lever can prevent that plunger from producing vibration and noise when crossing the transfiguration hole.Simple for structure, cost is low, and can realize single cylinder list notes, omits converter plant, thoroughly overcomes single pump individual well and the existing disadvantage of many wells of pump technology.
Description of drawings
Fig. 1 is that pump structure figure is regulated with the ratio that ternary is injected and polymer injects in the oil field.
Fig. 2 is the transfiguration hole structure figure on the adjustable lever.
Among the figure: 1, adjustable lever, 2, stuffing box gland, 3, the transfiguration hole, 4, plunger.
Embodiment
Pump is regulated with the ratio that ternary is injected and polymer injects in oil field shown in Figure 1; An adjustable lever 1 and a stuffing box gland 2 are set in pump head; Transfiguration hole 3 is set on the adjustable lever 1, and stuffing box gland 2 and adjustable lever 1 seal through the gap, and change the position of adjustable lever 1 through the screw thread transmission.
Transfiguration hole 3 on the adjustable lever shown in Figure 2 is made up of two rule parts, and the left side is a semicircle, and the right side is for being the isoceles triangle shape on base with the semicircle diameter.
The working principle that ratio is regulated pump is: the right side in transfiguration hole 3 is called seal area; If plunger 4 is in seal area fully in the to-and-fro motion process, the trip is an effective travel, if but plunger 4 has been crossed transfiguration hole 3 in the to-and-fro motion process; Get into the non-tight district; That stroke of crossing transfiguration hole 3 then is backlash, can just can change the relative position of transfiguration hole 3 with respect to plunger 4 through regulating the position of adjustable lever 1; Thereby set the effective travel size of pump, realize the adjusting of pump duty.
