| 中文摘要:我们在四川施工了5口煤层气井（其中参数井4口），各项参数反映四川煤层气具备了开发和小井网试采的储层条件。但在施工中存在钻探进度慢、测试坐封选层难、井斜控制难、煤层对比和采取率不甚理想、煤储层污染严重等问题。通过分析，提出采用“三开”井身结构、防斜打直、进一步开展大口径绳索取心的攻关、储层保护等建议，以推进四川煤层气的勘探开发中钻探技术上的保证。 |

| Abstract:We have consturcted 5 coal bed methane wells（there are 4 parameter wells) in Sichuan. The parameters reflected the procession of reservoir condition for coal bed methane development and small network of production test in Sichuan. But there are still serious existing problems such as slow drilling process, difficult layer selection for setting test and hole deviation control, coal seam correlation and coal recovery not ideal as expected and coal reservoir pollution. Three spuds well structure, deviation control with drilling straight, research on large diameter wire line coring and reservoir protection were suggested by the condition analysis to promote the drilling technical guarantee for coal bed methane exploration and development in Sichuan. |
