摘要
水平井地质导向是水平井成功与否的关键技术。针对尕斯库勒油田N1—N21油藏储层岩性变化快、岩屑代表性差和地层倾角变化大等技术难点,从井位部署优选入手,深入分析油藏构造特征、加强精细地层对比、紧密结合综合录井资料,形成了一套适用于该油藏的水平井地质导向技术。在多口水平井钻探过程中,获得了较好的应用效果。
Horizontal well geosteering is the key technique for the success of horizontal well.According to the technical problems such as the great changes in reservoir lithology and formation dips,and poor rock debris representative of cuttings of the Gasikule oilfield N1-N21 reservoir,starting with the optimization of well deployment,with in-depth analysis of reservoir structural feature,strengthening of stratigraphic correlation,combination of comprehensive logging data,a set of horizontal well geosteering technology which is applicable for this reservoir has been established.Good application has been achieved during the drilling of horizontal wells.
