喇嘛甸油田特高含水期注采无效循环识别方法

Identification method of ineffective circling of injection-production in high water cut period in Lamadian Oilfield

利用精细地质研究成果并借助各种动静态资料,对喇嘛甸油田特高含水期注采无效循环状况进行了详细的研究,搞清了特高含水期储层内无效循环的形成条件、分布状况和特征参数的变化规律,形成了一套判别油层内注采无效循环通道的技术方法。

status With dynamic and static data, and results of fine geologic studies, this paper studies ineffective circling of injection -production in high water cut period in Lamadian Oilfield, confirms forming conditions and distribution status of reservoirs ineffective circling and change rules of characteristic parameters, and establishes a set of technical method for determining ineffective circling channel in reservoirs.
