Abstract
Description
technical field
[0001] The invention belongs to the field of oil field chemical industry. Specifically, the invention relates to an oil-based wax remover. More specifically, the invention relates to an oil-based wax remover with high flash point and strong environmental protection. Background technique
[0002] Waxing in oil wells is a common phenomenon in oilfield development, especially in the process of heavy oil production, where the wax content is high. During the production process, as the pressure and temperature decrease, the wax contained in the crude oil gradually precipitates out, and the oil well pipe string and the ground collection The paraffin wax deposited in the oil pipeline will reduce the effective cross-sectional area of the pipeline or even block it, resulting in a decrease in pump efficiency and a decrease in oil well fluid production. , And thus cause problems such as increased power consumption of the pumping unit and increased failure rate. The pr...
