塔河油田三叠系水平井地质导向技术研究

针对塔河油田三叠系碎屑岩油气藏油层薄、储集层非均质性较强、泥质和低渗致密夹层纵横向变化大的地质特点，在分析、研究不同区块多口水平井资料的基础上，探讨了水平井不同地质情况下斜井段及目的层砂顶的预测和判别技术，以实例阐述了井眼轨迹调整方法，首次形成了一套适合于该地区碎屑岩非均质薄层油气藏水平井录井地质导向技术，在塔河油田水平井钻探开发中取得了显著的成效。

Study on geologic steering technique for horizontal wells of Triassic system in Tahe Oilfield

According to the geologic characteristics of thin oil and gas reservoir, strong heterogeneous, and great lateral variation in the interbed of the shale and low permeability in the Triassic system clastic rock in Tahe Oilfield, on the basis of analyzing and studying the information of many horizontal wells of different areas and blocks, the author discussed the predicting and discriminating technique for the sand top of slant hole section and target zone in different geologic condition of horizontal wells, expounded the adjusting methods for the well track with applied examples, firstly formed a set of geologic steering technique for the horizontal well logging in the clastic rock and heterogeneous thin oil and gas reservoir for the area, which got the remarkable achievements during the horizontal well drilling and exploration in Tahe Oilfield.
