摘要/Abstract

摘要： 牙哈2-3凝析气田采用循环注气部分保压方式开发,历年的压力监测资料表明压力解释结果异常,采气井压力恢复测试的地层压力普遍高于注气井压降试井的地层压力,给动态分析带来了很大的困难。通过现场测试资料的分析,总结出地层压力异常的原因,并对其进行校正以得出较为可靠的地层压力。解决了几年来该气田测试地层压力异常的困惑,对于气田的科学管理有较重要的指导意义。

Abstract: The partial pressure maintenance and cyclic gas injection processes were used for development of Yaha 2-3 gas condensate reservoir in Tarim oilfield. But in past years, the pressure monitoring data showed that the reservoir pressures of build-up test data from gas producer were higher than that of build-down test data from gas injector, allowing the related performance analysis to be difficult. This paper analyzes the field testing data, finds out the reasons for abnormal formation pressure and makes corrections to them in order to attain reliable formation pressure. Such a big problem appeared by formation pressure test in past years has been solved, being of more significance for scientific management of the gas fields.

Key words: pressure build-up test, pressure build-down test, well interference, cyclic gas injection
