基于模糊评判的分层堵水方案优选

An Optimization Method for Selecting the Water Plugging Target Zones

堵水是提高采收率、降低产水量非常有效的方法。恰当的选择目标井和目标层是至关重要的,否则,就会影响堵水的效果。通常,优选目标井和目标层的工作是人为的,而且是不严密的,因此,堵水并不能达到预期的效果。这里提出了一种最优化选择堵水井层的模糊方法,这项研究成果对于油田开发的堵水技术有着重要的意义。

Water plugging is quite an efficient way to enhance recovery ratio and reduce water production rate. It is rather important to select the target wells and target zones properly, otherwise we won＇t get a good result from water plugging operations. Usually, the jobs of selecting the target wells and target zones are done artificially and not perfect. As a restlt, water plugging can＇ t reach the expected effect. In this paper, a fuzzy model has been proposed to optimize the selection of target wells and target zones for water plugging, which will have a vital significance on water shutoff technology for oilfield development.
