沁水盆地东南部煤层气裸眼完井开发研究

Qinshui Basin Southeast coalbed Methane Naked Eye Well Completion Development Study

为了探寻不同开发区块与地质条件下的最优煤层气开发井型,基于目前沁水盆地东南部10口实验性裸眼井开发的数据整理与分析,从产水、产气、套压与施工难度等方面简单对比了裸眼完井与同区块、相近区域套管完井存在的巨大差异;分析了此区块裸眼完井产能不佳的内、外在因素;得出此区块以及其他类似的软、粉煤区块在裸眼完井开发工艺未有突破性进展前施工的成功率较低。

In order to explore the different development blocks and geological conditions of the optimal type of coalbed methane development well, based on the data collection and analysis of present Qinshui basin southeast 10 experimental naked eye well, from comparison of water production, gas production, casing pressure and difficulty of construction, etc, between naked eye well and similar blocks, regional casing well completion, with huge difference; This block open hole completion poor capacity of internal and external factors were analyzed; This soft, pulverized coal, and other similar the block in front of the development of open hole completion technology no breakthrough construction success rate was low.
