摘要
分析了多层超薄低渗油藏的开发难点 ,指出采用欠平衡水平井技术是开发该类型油藏的有效方法。以纯 70 -平 1井为例 ,详细介绍了欠平衡水平井钻井技术的应用情况 ,该井投产后 ,产能是邻井的 6～ 8倍 ,增产效果非常明显。
The paper analyzes the critical points of developing multi layer, ultra thin, low permeable reservoirs and provides the solving measures. It is pointed out that under balanced horizontal well technique is an effective way to develop this kind of reservoirs. Taking the Chun 70 Ping 1 Well as an example, the paper introduces the application of UBD. The producing capacity of this well is six to eight times of that of adjacent wells after putting into production. The success of the well accumulates valuable experiences for later similar wells.
