摘要
求取煤层参数、评价区域内的煤层气开发前景,是煤层气测试的主要目的。受限于注入量小、关井时间短、探测半径小等因素,测试取得的参数往往不能很好反映储层物性。因此,需要从测试类型的选择、测试液体的配伍性、测试设备、管柱结构及参数的优化等方面,对煤层测试工艺进行改进,形成煤层气测试工艺技术。优化后的注入/压降测试是获得煤储层物性的主要手段,EPS测试软件能较可靠地分析测试数据。
The main purposes of CBM testing are to gain the reservoir parameters and evaluate the development prospect. Limited by low injection volume, short shut-in time and small detection radius, parameters gained by testing often can not reflect reservoir properties well. Therefore, the coal seam testing technology is needed to be improved by selection of testing types, compatibility of testing liquid, testing equipments, string structure and parameter optimization to form CBM testing technology. It is concluded that injection/drawdown tests after optimization are the main methods of obtaining the coal seam properties. ESP testing software can an-alyze the test data more reliable.
