摘　　要：克拉美丽火山岩气田包括滴西17、滴西14、滴西18和滴西10等主要气藏,不同井区开发效果差异明显,且同一井区不同井单井产能也存在较大差异,产能的不确定性严重影响了克拉美丽气田的高效开发。通过对克拉美丽火山岩气田的岩相、岩性、断裂发育程度和钻完井工艺等方面的分析,认为气藏的火山岩岩相、岩性是影响气井产能的主要因素,爆发相和火山角砾岩、正长斑岩、英安岩产能高。另外,裂缝的发育、欠平衡作业与水平井钻井也是促使克拉美丽气田产能较高的原因。Kelameili Volcanic Gas Field was mainly composed of 4 important gas reservoirs,namely Dixi 17,Dixi 14,Dixi 18 and Dixi10 Reservoirs.There existed huge difference of development effect in different wellblocks,while in the same wellblock,there existed big difference of production in different wells.The uncertainty of productivity seriously influenced high effective production of the gas field.By analysis of volcanic lithofacies,lithology,fault development extent,drilling and completion technology,it was considered that the volcanic lithofacies and lithology are the primary affecting factors of gas well productivity.In view of lithofacies,explosive facies volcanic breccia,orthophyre and dacite are high productivity.Besides fracture growth,under-balanced drilling and horizontal well drilling are also important affecting factors yielding high productivity.
