Q7断块阜二段油藏物性差，储层单层厚度薄，油井自然产能低甚至无产能，常规井控制储量小，产能递减快，采用常规水平井开发受油藏物性、厚度等条件限制，经济有效开发难度大。针对 Q7断块油藏特点，利用对物性差、油层厚度薄、油层段集中的油藏具有技术优势的长水平段分段压裂水平井，通过形成多条横向缝，增加垂向渗透率，并将不同油层连接起来，提高单井产能，实现有效开发。在 Q7断块地质模型基础上，应用油藏数值模拟方法对水平井单井参数进行优化设计研究。

Second member of Funing formation (E 1 f2 )of fault block Q7 is characteristics of poor physical property, thin thickness of single layer,low natural production capacity even no production,small control reserves of conventional well and quick production decline.The use of the conventional horizontal well developing method is usually restricted by conditions such as reservoir physical property,layer thickness,and so on,which lead to more difficult effective development with economic way.For reservoirs with poor physical property,thin layer thickness and relative concentrated oil interval,the multi -stage fracturing technology has certain technical advantages.Therefore,this technology was applied to increase sin-gle well production and realize effective development of oilfield through forming multiple transverse cracks,increasing verti-cal permeability and connecting different reservoir layer.According geological model of fault block Q7,reservoir simulation is used to study on optimal design of horizontal well parameters.
