摘要
Abstract
The geology of Halfaya Oilifeld is complicated and there tends to be problems such as bit balling, creepage hole shrink-age, pollution of high density drilling lfuid by high concentration Ca2+during the drilling. The dififculties in maintenance of drilling lfuid are inhibition of soft mudstone distribution, stabilization of pH value and elimination of Ca2+. Through selection and optimization of treating agent of drilling lfuid, BZ-HIB and BZ-DCA are introduced and technical measures are improved to solve the problems with control of rheological property of high density mud, stabilization of pH value, and elimination of Ca2+. It has signiifcant effects on in-crease of drilling rate and reduction of dififculty in maintenance.关键词
