Oil pipe inner wall cleaning machine for oil development

Abstract

An oil pipe inner wall cleaning machine for petroleum exploitation comprises a collecting pond device (1), an oil pipe clamp device (2), a heating device (3), a cleaning platform device (4), a power head (5) and a cleaning rod device (6). The oil pipe clamp device (2) is arranged on the collecting pond device (1) and can slide relative to the collecting pond device (1). The heating device (3) is arranged on the collecting pond device (1) and heats the oil pipe clamp device (2). The cleaning platform device (4) is arranged on the collecting pond device (1). The power head (5) and the cleaning rod device (6) are arranged on the cleaning platform device (4). The power head (5) is connected with the cleaning rod device (6). By means of the oil pipe inner wall cleaning machine for petroleum exploitation, batched oil pipe treatment is achieved, and the usage amount of oil pipes during petroleum exploitation is reduced; and meanwhile, the cleaning efficiency is high, cost is low, the usage amount of water in the cleaning process is small, the using process is environment-friendly, and meanwhile the oil pipes are not damaged when the oil pipe inner wall cleaning machine penetrates the oil pipe.

Description

technical field [0001] The invention belongs to the field of cleaning devices, in particular to a cleaning machine for the inner wall of oil pipes used in oil development. Background technique [0002] In oil production, oil pipe consumption accounts for 40%-50% of the main material cost. Controlling oil pipe usage is the key point for oil production plants to reduce costs and increase efficiency. Improving oil pipe repair rate is the most direct and effective way to achieve this goal. way. [0003] After the oil pipe is used for a long time, oil stains, dirt and other impurities will adhere to the inner wall of the oil pipe, and the scale will be serious, with a thickness of 10-20mm. Its main components are calcium carbonate and sulfate, and it also contains a small amount of Fe. 2 o 3 , BaSO 4 , SrSO 4 And other ingredients, dense and hard. Regular cleaning is required to remove impurities on the inner wall of the oil pipe. [0004] The current cleaning methods for t...

Problems solved by technology

This method often causes the drill bit to be stuck or the joint to be twisted off, and the thick oil and wax blocks in the dirt inside the tubing (wax is solid at room temperature and dissolved in crude oil, during the process of being pumped out from the ground to the ground, due to the temperature and the reduction of pressure, which reduces the solubility of crude oil to wax, precipitates from crude oil, sticks to the inner wall of the oil pipe, and continuously grows and deposits) is still not easy to solve, especially in low temperature areas or seasons. During the process, it is scraped off The thick oil and wax will wrap the drill bit and cannot be washed down by water. After processing a few oil pipes, it is necessary to stop cleaning and take out the drill bit for cleaning. The work efficiency is low
