摘　　要：苏里格气田西区苏54区块为典型的低孔、低渗致密砂岩气藏,完钻井出水较严重,气水分布关系复杂,主要控制因素不明朗,开发难度较大。通过对苏54区块构造、沉积相、砂体及渗砂体展布及储层特征研究,认为苏54区块气水分布的主要控制因素有气源、沉积相、构造、物性及裂缝等因素,明确了主力目的层段的气、水分布特征及含气相对富集区。区块中东部含气性较好,是近期开发的有利目标区带,可在保证合理井网的基础上优先布井。西部及南北部相对富水,部署井位时应尽量避开富水区域。Su 54 area in Sulige gasfield＇west is a typically low porosity and low permeability tight sandstone gas reservoir, the water in drilling and well completion is serious, gas-water distribution relations is complex, main control factors is unclear, the development is difficult.Through to Su 54 area＇structure, sedimentary facies, sand body and permeability of sand body distribution and reservoir characteristics research, thinking Su 54 area gas water distribution of main control factors are air source, sedimentary facies, structure, physical properties and fracture, has been clear about the main purpose of interval of gas, water distributionand the relative gas enrichment region.Blocks in east-central hydrocarbon content is good. It is the recent development of potential target areas, to ensure the reasonable well pattern in priority on the basis of well spacing. The western and northern relatively rich water, should try to avoid the water enrichment area deployment location.
