Abstract

The present invention relates to the technical field of oil field exploitation, in particular to a (0-70Mpa) pressure-adjustable tracer plunger pump, including a base, a pressure-adjustable plunger pump, a pressure indicating gauge and a pressure regulating valve. A pressure-adjustable plunger pump is fixedly connected, and the upper end of the pressure-adjustable plunger pump is fixedly connected with a pressure regulating valve and a pressure indicator distributed in left and right directions, and the left end of the pressure-adjustable plunger pump is fixedly connected with an input cylinder , the left end surface of the input cylinder is fixedly connected with a connecting device, the left end surface of the connecting device is fixedly connected with a connecting pipe, and the other end of the connecting pipe is connected with a filtering device; in the present invention, through the provided connecting device, rotating cylinder and sealing The rotating cylinder squeezes the connecting ring through the spiral connection between the rotating cylinder and the rotating tube, and then under the action of the sealing ring and the rubber pad, it has a good sealing performance, and the connecting ring is not easy to be squeezed and damaged, ensuring its pressure Normal, to ensure the normal use of the plunger pump.

Description

Technical field [0001] Technical Field The present invention relates to oil exploration, in particular (0-70Mpa) adjustable pressure piston tracer. Background technique [0002] A hydraulic piston pump is an important system, it relies on the plunger reciprocates in the cylinder, the working volume of the sealing cavity changes to achieve suction, oil pressure, piston pump having a high pressure rated, compact, efficient high flow rate and easy adjustment, are widely used in high pressure, high flow rate and the flow rate to be adjusted occasions, such as hydraulic, machinery and ship construction. [0003] During the development of the well, the oil enters the oil in the late development stage, usually employed in the formation water to a way to keep the pressure reservoir, so as to improve ultimate recovery, and the external piston in such a manner connections would often discouraged leak occurs, so that the pressure becomes smaller, the water tank and the headbox substance occ...

Problems solved by technology

[0003] In the process of oil well development, after the oil field enters the middle and late stage of development and oil production, water injection into the formation is generally used to maintain the pressure of the oil layer, so as to achieve the purpose of improving the ultimate recovery. In this way, the plunger pump and the external Air leakage often occurs at the connection, which makes the pressure smaller, and the substances in the water tank and material tank cannot be pumped out in time, and the water in the existing water tank will not be filtered, which is inevitable after long-term use A large amount of solid impurities are produced, and these impurities are likely to affect the normal use of mechanical parts such as plunger pumps and check valves. At the same time, in order to obtain information on the injection status of layers and small layers, oilfields widely use tracer methods to measure and analyze The water injection effect of water injection wells, the previous technology is to connect the tracer injection device in parallel to the water injection pipeline, and inject the tracer into the formation through water injection and splitting. The disadvantage of this injection method is that the tracer cannot be clearly understood. Whether it is all injected into the formation, therefore, a (0-70Mpa) pressure-adjustable tracer plunger pump is proposed to solve the above problems
