葡扶234-平84井位于松辽盆地中央坳陷区大庆长垣葡萄花构造。该井完钻井深斜深3555米,垂深1691.4米,水平段长1718米。该井三开设计水平段长达到1500多米,施工密度也是大庆地区油包水钻井液之最。油包水钻井液较水基钻井液有着优异的性能,一直是解决特殊工艺井及复杂地层的有效钻井液体系之一,例如其良好的润滑性和滤失造壁性,适用于水敏性地层和含大段可溶性盐地层,保护油气层效果好,可避免钻具发生腐蚀,还具有可重复利用等特点,较好的解决了这一技术难题。
Pu-234-Ping-84 well is located in the central Songliao Basin Daqing Changyuan grape flower structure. Drilling completion of the deep well 3555 meters deep, down 1691.4 meters, the horizontal section of 1718 meters long. The well three open design level of more than 1,500 meters long, construction density is also the most Daqing oil and water drilling fluid. Water-in-oil drilling fluids have superior performance over water-based drilling fluids and have long been one of the most effective drilling fluid systems for solving special process wells and complex formations, such as their good lubricity and filtration-loss wall build-up, water sensitivity Stratum and a large section of soluble salt strata, to protect the effect of oil and gas well, to avoid corrosion of drilling tools, but also has the characteristics of reusability, a better solution to this technical problems.
