摘　　要：针对卫 2断块气顶油气藏的地层倾角陡、油环条带窄 ,油气藏开发过程中油井气窜严重、油气资源不能合理利用这些问题 ,深入细致地开展了构造、储层、天然气储量动用状况及剩余气分布等方面的综合研究 ;认清了气藏构造破碎、气顶储量分布复杂 (既有纯气藏 ,又有气顶油气藏 )、气顶采出程度较高但各断块 (砂组 )间差异大等方面的特点 ;在此基础上 ,对卫 2断块气顶气藏的下步开发政策进行了论证 ,提出了在不影响油环开发原则下优先动用纯气断块或油环很小的砂层组的具体开发对策 。In consideration of the problems in block Wei 2, such as unique geological conditions, steep dip angle in formation, narrow ribbon of oil ring, serious gas channeling in oil well during the development and unreasonable use of oil and gas resources,a careful study on the conditions of geological stucture, reservoir, utilization of gas reserve and remaining gas distribution is carried out and characteristics of tectonic crushing of a gas reservoir, complex distribution of gas cap reserve (pure gas reserve and gas cap reserve), high level of gas cap production and big difference among the blocks (sand group) are brought forth On the basis above, the further development policies of block Wei 2 are discussed,and it is proposed that concrete developmental countermeasures are taken to give priority to the production of neat gas block or very small oil ring sand group without influencing the development of oil ring to provide scientific evidences for correctly making up a plan for gas stimulation
