塔河油田深水平井钻井液技术

Deep Horizontal Drilling Fluid Techniques in Tahe Oilfield

介绍了正电胶聚合物混油钻井液体系和聚磺混油钻井液体系的基本配方、维护措施及在塔河油田 6口水平井的现场应用情况 ,指出正电胶聚合物混油钻井液的抗温性较差 ,维护处理困难 ,但携岩能力强 ;聚磺混油钻井液体系的性能稳定、维护方便 。

The basic formula, maintaining measures and its applications in six horizontal wells of the MMH-polymer oil-mixture drilling fluid system and polysulfonate oil-mixture drilling fluid system are introduced in this paper. It is pointed out that it is difficult to maintain the MMH-polymer oil-mixture drilling fluid system and its property of anti-temperature is bad, although its ability of carrying debris is good. However, it is convenient to maintain the polysulfonate oil-mixture drilling fluid system and it is deserved to be widely used.
