摘要
针对准噶尔盆地煤储层特性开展了储层保护及钻井液评价实验,欠平衡钻井方式选择评价分析,多分支井身结构实施方案及工序,以及现有煤层气取心工具的改进等初探研究。获得煤储层敏感性评价等相关实验数据,优选充气欠平衡钻井方式以及多分支水平井主、分支井眼实施工序,优化煤层气取心工具,以此为新疆准噶尔盆地煤层气的有效开采提供工程技术的借鉴。
According to the protection of Zhungar Basin coal reservoir,we developed the reservoir protection and drilling mud evaluation experiments,under-balanced drilling methods evaluation and analysis,multilateral well construction implements scheme and processes,and did some research work on coal-bed gas coring tools improvement.According to the sensitivity evaluation of the coal reservoir data,we optimized the aerated UBD technology,multilateral well implementing scheme and processes,and optimized the coal-bed gas exploration in Zhungar Basin in Xinjiang of China.
