B301试验区油井结蜡主控因素及对策
Main Control Factors and Countermeasures for Oil Well Waxing in B301 Test Area
摘要
Abstract
The waxing is severe,the antiwaxing effect is poor,and the validity period is short in oil wells in B301 test area of H Basin.So,it is urgent to find out the main controlling factors affecting wax formation to meet the needs of antiwaxing in oil wells.To address the above problems,the wax,gum,asphaltene,and mechanical impu-rity contents in the produced fluid were measured by indoor experiments.Olga numerical simulation software was used to simulate the temperature,pressure,and flow rate.The study shows that wax,asphaltene,mechanical im-purities,temperature,and flow rate are the main controlling factors affecting wellbore waxing in B301 test area,and the degree of influence is in the order of wax,temperature,asphaltene,mechanical impurities,and flow rate.The research results provide a theoretical and technical basis for further efficient development of B301 test area and a reference for anti-waxing methods in highly waxed oil reservoirs.关键词
