韩城PSC区块煤层气压裂工艺应用效果分析
|
摘要
为了促进对韩城PSC区块煤层气规模化开发,对近年来压裂工艺应用效果进行了研究分析,结果表明:活性水压裂工艺效果与煤储层本身特征有关,一般煤层较致密,孔渗条件较差的干煤层,其压裂效果较差;同步压裂工艺及间接压裂工艺在研究区应用效果较好,可进一步扩大应用范围;而复合压裂液工艺在该区应用效果较差,可进一步研究该区煤储层特征,完善清洁压裂液配比方案及工艺流程。
According to the application of fracturing technology in PSC block Hancheng region in recent years,the paper points out that the effect of active water fracturing is related with the coal reservoir characteristics, commonly, tighter reservoir means worse effect of fracturing. Synchronous fracturing and indirect fracturing has obtained favorable results,which can be applied in larger range. Effect of compound fracturing method is poor in the area,which requires further study on coal reservoir characteristics and improvement of clean fracturing fluid proportion scheme and process.
