微珠低密度水泥在低压地层固井中的应用——浅谈长山工程

Application of Micro-Particle Low-Density Cementin Well Cementation in Low Pressure Stratum--A Brief Discussion on Changshan Project

G级油井水泥是高温深井水泥,它与各类水泥外加剂具有很好的相容性,完全可以满足现场施工要求,同时可显著降低水泥浆成本。通过威西构造长山矿区十余口井的低密度水泥固井施工,固井合格率达100%,取得了明显的经济效益。

G-grade cement for oil wells is used in deep wells with high temperature and is greatly compatible with various types of cement and admixture.It can completely meet the requirement of in situ construction and remarkably lower the cost of cement mud.In the cementation of a dozen wells with low density cement in Changshan Concession of Weixi Structure,qualification rate reaches 100% with remarkable economic results achieved.
