摘要
从钻井液体系配方研究入手,针对大港油田的地层特性,研究出2套钻井液体系配方,并对2套钻井液体 系的防塌性、油层保护性进行了室内评价,评价结果表明,2套钻井液体系具有较好防塌效果及油气层保护效果。
The experiments studied the question of hole collapse prevention and reservoir protection based on the composition of the drilling fluid. The study has developed composition of two kinds of drilling fluids according to characters of the Dagang Oilfield stratum. PA and JHY were added in the drilling fluids. The result shows that two kinds of drilling fluids both have better properties of collapse prevention and reservoir protection.
