摘　　要：塔里木盆地HD水驱砂岩油藏为受构造和地层双重控制的复合油藏,整体采用水平井开发,不同区域含水差异较大。应用水平井渗流规律,结合水平井产液剖面测井、试井等动态监测资料,揭示水平段内表皮效应差异是加剧或减弱层内矛盾的根本原因,探讨生产压差调控对开发效果的影响,据此指导相关的生产及措施调整,对油田水平井稳油控水及高效开发具有积极作用。HD water drive sandstone reservoir in Tafim basin is a complex reservoir with water cut differential in different areas controlled by structure and stratigraphy, which is developed by horizontal wells on the whole. Based on the percolation law of horizontal wells, integrated with performance monitoring data from the fluid producing section logging and production testing of horizontal wells, this study reveals that the differential of skin effects within horizontal intervals is an essential reason for aggravating or weakening the intrastratal contradictions. And the effect of regulating producing pressure differential on development effectiveness is studied for guiding related production and measure regulation, keeping the production stable while bringing the water-cut under control as well as highly effective development by horizontal wells in this area.
