摘要
塔里木油田哈得 4号构造上的 C 和 C 油层厚度分别为 0 .9m和 1.5 m,用常规水平井及随钻测量系统开发具有施工难度大、成本高的问题 ,为此 ,采用了阶梯式水平井技术、配合应用 FEWD系统对这两个薄油层进行开发。已完成的 8口薄油层水平井的平均油层穿透率 87.35 % ,原油产量是直井的 3.6倍 ,经济效益非常显著。重点介绍FEWD仪器的原理、传感器的特性、施工要求、采取的措施以及在哈得逊油区的具体应用情况。
The two thin producing layers located on the Hade 4 structure in Tarim oilfield were exploited by using staircase horizontal drilling techniques and FEWD system. The average penetrating ratio of eight horizontal wells drilled in thin reservoirs is 87.35 percent and its producing capacity is 3.6 times of that in straight hole. Their economic benefits are very remarkable. The mechanisms of FEWD, the features of sensor, the requirements of operation and field applications in Hadexun oilfield are emphasized.
