三维地质模型在T井区水平井设计中的应用

摘要

应用petrel软件,根据工区地质条件和沉积特征等相关信息进行随机模拟,建立水平井目的层的三维地质模型.文中通过有利储层的分析,部署水平井井位;经过地应力及裂缝方向研究,确定水平段的方位;根据Joshi理论公式计算本区水平井产能替换比,论证出水平段的长度;结合现场录井情况验证模型的合理性.%The 3D geological model of purpose layer of horizontal well is established with the petrel software according to the random simulation of the related information such as geological conditions and sedimentary characteristics of the area. The well position is deployed by analyzing favorable reservoir;the orientation of horizontal section is determined by studying the direction of stress and fractures and the length of the section is demonstrated according to the ratio of production capacity which is based on the Joshi theoretical formula. Furthermore,the reasonableness of model is verified by the logging practices.
