High-efficiency wax-proof, scale-proof and liquid-increasing device

Abstract

The invention relates to the technical field of petroleum exploitation, and discloses a high-efficient wax-proof, scale-proof and liquid-increasing device. The high-efficient wax-proof, scale-proof and liquid-increasing device comprises a deep well, wherein an oil sucker rod is arranged in the deep well in a penetrating mode, a seven-split rod oil sucker rod wax-proof device is fixedly connected to the bottom end of the oil sucker rod, and a six-split rod oil sucker rod wax-proof device is fixedly connected to the bottom end of the seven-split rod oil sucker rod wax-proof device. Through the integration of high intensity magnetic, acoustic wave and eddy current technology, the high-efficiency wax-proof, scale-proof liquid-increasing device can perform the before pump and after pump treatment on well water-bearing crude oil. The unique design structure of the device can enable the flow rate, flow pattern, temperature, pressure, viscosity, the solubility of gas-liquid phase, the mixing degree of solid-liquid phase, the environment of crystal adsorption and growth, the microstructure of hydrocarbon components and so on of the produced liquid to produce a series of physical changes, the produced liquid is highly melted, so that the amount of wax is greatly reduced, the washing cycle is prolonged, and remarkable effects of wax-proof, scaling-proof, viscosity-proof and oil-increasingare achieved. A good wax-proof and scale-proof method is achieved.

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, in particular to a high-efficiency anti-wax, anti-scaling, anti-scaling and liquid-increasing device. Background technique [0002] Generally, crude oil has high wax content, high viscosity, and poor fluidity, which bring great difficulties to well washing operations. [0003] There are two common well cleaning methods on the market: the first is chemical cleaning, which has no special requirements for well selection, and has the advantages of saving the amount of hot washing liquid and taking up less production time, but the well cleaning cycle of this method is short , the wax removal is not thorough, especially for the casing fluid, and it needs to be supplemented by hot washing regularly; the second method of nylon wax scraping has no special requirements for oil wells, but this method has a short cleaning cycle and incomplete wax removal. Regularly supplemented with a hot was...
