张渠二区开发效果评价

Evaluation of development result of Zhangqu-2 area

从水驱开发效果评价指标体系入手,结合张渠二区开发实践,对储量动用程度、可采储量、存水率、水驱指数、注入倍数等指标进行了客观分析,认为张渠二区的总体开发状况良好,但也存在不利因素,水驱控制程度低是目前制约开发效果进一步改善的主要因素.

The objective evaluation of water-flooding development result is the key to search for further development potential tapping measures,improving development conditions and enhancing development result. Combining development practice of the Zhangqu-2 area,the water-flooding development result evaluation indexes——reserves exploitation degree,recoverable reserves,water storage rate,water drive index,injection volume,etc.of the studied area are objectively analyzed,and it is held that the general development state of the area is better.But there are still some unfavorable factors to the development result.Of them,lower control degree of water drive is an important factor of restricting the development result at present.
