| 摘 要： | 通过对白马崾先地区延长组长4+5油藏烃源岩的分布、构造特征、有利相带、低压等因素的系统分析研究,认为烃源岩是形成油气藏的物质基础；局部隆基构造是油藏形成的前提；水下分流河道是该区长4+5油藏的储集体；上倾方向的岩性遮挡条件是油气保存和富集的保证；低压是油气藏形成的重要条件.在此基础上划分了5个有利区带GG27井区、GG70井区、GG02井区、GG13井区、GG81井区等.

| Abstract: | Distribution of source rocks,structural feature,favorable facies belt and low-pressure factors of Yanchang formation Chang 4+5 reservoir in Baimayaoxian area were analyzed and studied.The results show that source rocks are the material basis to form oil and gas reservoir,local uplift structure and sand body organic configuration provide favorable conditions for oil and gas enrichment,underwater distributary channel provides space for oil and gas enrichment,low pressure under the role is important conditions to form oil and gas reservoir.On this basis,five favorable zones have been divided as follows: GG27 Well area,GG70 Well area,GG02 Well area,GG13 Well area,GG81 Well area. |
