曙4-H105井周围邻井较少,局部地层倾角变化较大,此外油层较薄、夹层发育给地质导向工作带来很大难度。在本井实施过程中,地质导向师根据钻前室内油藏地质研究,结合各种实钻地质信息,实时引导轨迹准确入靶,确保水平段有效砂岩钻遇率和在油层位置的优化,取得不错的效果,为今后在该区块推广水平井及水平井地质导向技术积累了宝贵经验。
There are fewer adjacent wells in Shu 4-H105 well, and the dip of local strata varies greatly. In addition, the thin oil layer and the development of the interlayer bring great difficulty to the geosteering work. During the implementation of the well, the geogastric division, based on the study of pre-drilling reservoir oil and gas, combined with various geological drilling geological information, guides the trajectory to the target in real time and ensures the effective sandstone drilling ratio in the horizontal section and the optimization of the reservoir location. Good results for the future in the promotion of horizontal wells and horizontal well geological guidance technology has accumulated valuable experience.
