垣平1-7井是垣平1区块的一口水平采油井,该井设计井深3791.00米,垂深1604.18米,井斜90.82o,方位39.89o,1102.71m开始定向造斜,定向造斜段进尺669.29m,水平旋转导向钻进至井深3372m完钻,水平段进尺1600m。二开井段1643.00m,大井眼段贯穿嫩江组、姚家组和青山口组,包括大段的紫红色泥岩和青山口灰黑色泥岩,控制钻井液性能难度大。该井二开采用硅基阳离子水基钻井液体系。三开采用油包水钻井液体系。
The Yuanping 1-7 well is a horizontal oil production well in the Yuanping 1 block. The designed well depth is 3791.00 meters, the vertical depth is 1604.18 meters, the well inclination is 90.82o, the azimuth is 39.89o and the distance is 1102.71m. Footage 669.29m, horizontal rotation guide drilling to well depth of 3372m finished drilling, horizontal footage footage 1600m. The second well section is 1643.00m. The big well section runs through the Nenjiang, Yaojia and Qingshankou formations, including large sections of purplish red mudstone and Qingshankou gray-black mudstone, which makes it difficult to control drilling fluid properties. The well used to open the silicon-based cationic water-based drilling fluid system. Three open water-in-oil drilling fluid system.
