Description
Technical Field
The utility model relates to an oil deposit exploitation equipment field particularly, relates to a wax removal device for high wax-bearing gas lift well.
Background
Petroleum, one of the main objects of geological exploration, is a viscous, dark brown liquid, known as "industrial blood". The upper part of the crust has oil storage. The main component is a mixture of various alkanes, cycloalkanes and aromatics. The oil formation mechanism of petroleum has two theories of biological deposition and oil change and petrochemical oil, the former is widely accepted, and the petroleum is formed by the long evolution of organisms in ancient oceans or lakes, belongs to biological deposition and oil change and cannot be regenerated; the latter considers that oil is produced from the carbon in the earth's crust itself, is biologically unrelated and is renewable. Petroleum is mainly used as a fuel and gasoline, and is also a raw material for many chemical industry products such as solutions, fertilizers, pesticides, plastics, and the like, and petroleum is generally produced through oil wells.
The crude oil mixed liquid produced by oil field oil extraction machinery contains paraffin, the temperature of the gathering and transportation liquid discharged from the oil well mouth is reduced from about 40 ℃ to about 20 ℃ in the transportation process through the gathering and transportation pipeline, and the paraffin is condensed into solid paraffin and attached to the inner wall of the pipe in the process along with the reduction of the temperature and the pressure. After the wax is deposited on the inner wall of the pipe, the conveying aperture of the oil pipe is reduced, so that the conveying resistance of the collected fluid is gradually increased, the pressure of the conveying pipeline and the wellhead of the oil well is increased, and the yield of the oil well is reduced. In order to avoid wax deposition, the existing method is to mix hot water for transportation, namely, each oil transfer station heats water with a certain proportion to about 60 ℃ and sends the water to a wellhead, and then a gathering and transporting pipe is connected, so that the temperature of the oil well output liquid and the hot water is raised to more than 40 ℃ after being mixed and then the oil well output liquid and the hot water are transported out. The mixed gathering and conveying liquid is conveyed to a combined station for processing and separation, and the energy waste of the water-mixing heat conveying process is large.
At present, in the oil extraction and paraffin removal process, mechanical paraffin scraping, hot washing, electric heating and chemical paraffin removal methods are generally adopted, the defects are high cost, large workload and frequent paraffin removal, the production efficiency is seriously influenced, and most of oil wells in China at present use the traditional paraffin scraper method for paraffin removal, so that the time and labor are wasted, and the efficiency is low.
