应用地质建模技术，根据建模的对象、地质条件和沉积特征等相关的已知信息选择适用的随机模拟技术，建立水平井目的层三维地质模型设计。文中通过分析储层有利区的位置，部署水平井井位；经过地应力及水力压裂裂缝方向研究，确定水平段的方位；根据储层状况并结合压裂缝与产能的关系，论证出水平段的长度；投产初期增产效果明显。%In this paper, the reservoir geological model of purpose layer of horizontal well is established with the geological modeling according to the known information such as the modeling object, the geological conditions and the sedimentary characteristics after applying the random simulation techniques. The well position is deployed after analyzing the position of favorable area of reservoir; the orientation of horizontal section is ascertained after study- ing the direction of stress and hydraulic fractures; the length of the horizontal section is demonstrated according to the reservoir conditions combining the relationship of hydraulic fractures and capacity; it can be seen that the increase effect is significant.
