正电胶钻井完井液在官H2短半径水平井中的应用

Application of MMH Drilling and Completion Fluids in Short-Radius Horizental Well Guan No. H2

系统介绍了正电胶泥浆体系用于我国第一口短半径水平井──官Ｈ２并的成功经验。实践表明，该类型泥浆完全能够解决短半径水平井钻井过程中所遇到的各种与钻井液有关的技术难题，满足在大港油田钻这类水平井的施工要求。

The techniques of MMH drilling and completion fluids adopted in the first short-radius horizontal well(named Guan H2)in China were introduced in detail.It was shown from the drilling practice of the well that the various difficult problems encounted in short-radius horizontal drilling could be solved and all the reguirements of drilling engineering to the muds in Dagang Oilfield could be met by the use of this type of muds,combined with the rational drilling fluid techniques.
