摘要(Abstract)：
通过总结新集煤层气示范开发一期工程所钻的 1口评价井和 3口生产试验井的钻井、固井技术 ,提出了适合该地区煤层气评价、开发要求的钻井技术、煤储层保护技术、大口径绳索取心技术、变密度水泥浆固井技术等 ,为今后煤层气勘探开发提供了借鉴
Based on drilling and cementing technology used for 1 test well and 3 producing wells in Xinji coalbed methane pilot pattern,it is put forward that a set of advanced technolgy about drilling,reservoir damage prevention,wireline coring and low density cementing for CBM well.In addition,a set of academic base and practical method for China′s CBM exploration and development in future.
