Abstract

The invention discloses a wax removal method for a crude oil well. The wax removal method comprises the following steps of (A) fixing a winch next to the oil well, fixing a fixed wheel at the upper part of an oil well inlet, connecting one end of a wire rope and the winch, and connecting the other end of the wire rope and one end of a connection shaft after bypassing the fixed wheel; (B) starting the winch, lengthening the wire rope to make a wax removal assembly fall off along the diameter of the oil well, simultaneously starting a drive device, making a scraper assembly rotate around the connection shaft, and scraping a wax layer on the well wall; and (C) starting the winch, shortening the wire rope, and making the wax removal assembly drop out of the oil well. The wax removal assembly is put into the oil well requiring wax removal through the devices, such as the winch, and the wax on the wall of the oil well is scraped by a scraper blade in the scraper assembly, so that the negative conditions, such as crude oil circulation channel reduction, oil pressure rise and oil pipe blockage, are avoided to ensure smooth normal crude oil circulation and crude oil exploitation.

Description

technical field

[0001] The invention relates to a wax removal method, in particular to a wax removal method for crude oil wells. Background technique

[0002] Drilling is the project of using mechanical equipment to drill the formation into cylindrical holes with a certain depth. According to the way of rock crushing and the type of tools used, it can be divided into ton drill and rotary drill.

[0003] Ton drill, also known as impact drill. The drill bit is sent to the bottom of the well with a wire rope, and the beam mechanism is driven by power, so that one end of the beam moves up and down, and the wire rope and the drill bit are driven to produce an up and down impact to break the rock. The drilling speed of sudden drilling is slow, the efficiency is low, and it cannot adapt to the drilling requirements of increasing well depth and complex formations, and is gradually replaced by rotary drilling. But it has the advantages of simple equipment, low cost, no pollution t...
