Abstract

The present invention provides an oil-based wax clearing agent comprising, in parts by weight, 75 to 85 parts of an organic solvent, 15 to 25 parts of a co-solvent, 0.5 to 1.2 parts of a penetrant, and 1 to 3.5 parts of a solubilizer. The raw materials of the oil-based wax cleaning agent are easy to obtain, the specific gravity of the oil-based wax cleaning agent is higher than 0.85g / cm<3>, the flash point is higher than 60DEG C, substances such as S and Cl are not contained in the oil-based wax cleaning agent, and the oil-based wax cleaning agent is favorable for transportation, storage and safe on-site construction. Further, the oil-based wax cleaning agent has a wax melting rate at 45 DEG C of 0.040 g / min to 0.056 g / min, and has a high wax-dissolving rate on a basis of safe use.

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...
