柿庄南区块低效煤层气井产能释放技术研究

Study on production increased technology in south Shizhuang block of Qinshui coalbed methane field

柿庄南区块平均单井产气量低,严重制约了区块的高效开发,为了盘活储量巨大的低效井资源,本研究结合储层地质特征及低产原因,制定了一套精细化的产能释放技术,并进行了10口井的现场应用。应用结果表明:该套产能释放技术针对性强,平均单井产量达到措施前的3.5倍,该技术有效解决了柿庄南区块低产井问题,对同类型煤层气田提高开发效果提供了参考。

The average gas production of south Shizhuang block is low, which impede efficient development. In order to improve the development of the inefficient resource, which is of great reserve, an innovative research on formation characteristics and the cause of low production is made in this study. With the achievement of the research, a set of elaborate production release technology is formulated, which has been applied to 10 wells of the block.The application results showed that with the highly individualized technology, the production increased more than 3.5 times. The technology applied solved the low production well in south Shizhuang block and could improve the development effect of the similar type coalbed methane field.
