摘　　要：欢喜岭油田欢127东块兴隆台油藏属于以构造因素为主导的层状油藏,纵向上分上下两个油层组,含油面积1.46km2,石油地质储量805×104t,油藏埋深740～850m,属扇三角洲辫状河道沉积。油层自北西向南东倾斜,低部发育边水,属于边底水油藏。欢127东块兴隆台油藏埋藏浅,岩石胶结疏松,油井出砂非常严重,尤其是东、西两个边部,出砂导致油井不能正常生产而关井。2005年对5口井进行了压裂防砂试验,取得了不错的增油效果,为类似稠油油藏防砂提供了借鉴。The oil-bearing area of Xinglongtai reservoir is 1.46km2,geological reserves are 805 104t,reservoir buried depth is 740 - 850m,it has the characteristics of buried shallow,loose rock cement,serious sanding in Huan 127 East block of Huanxil-ing Oilfield,particularly in East and West side.The sand produc-tion can not lead normal oil production shut-in.Five wells had been carried out the fracturing sand controlling test in 2005,and achieved good increase production results,which also provided a reference for sand-control in similar heavy oil reservoir.
