| 摘 要： | 杏子川油田中生界油藏主要分布于上三叠统延长组长6、长2、长4+5油层组,尤其以长6和长2油层组油气最为富集.随着勘探开发工作的深入开展,陆续在该区发现长9、长8油藏,这两个油藏具有隐蔽、规模较小及发现难度大的特点.研究发现,长9、长8油藏分布主要受控于沉积相带,鼻状隆起是油气富集的重要条件. |

| Abstract: | The main reservoirs in the Mesozoic of Xizichuan oilfield are distributed in Chang 6,Chang 2,Chang 4+5 of Triassic Yanchang formation,especially enrichment in Chang 6 and Chang 2.With the development of exploration,Chang 9,Chang 8 reservoirs continue to be discovered,which is subtle,small sized and harder to discover.The present study shows that they are cont rolled by multiple factors.The distribution of reservoirs is mainly cont rolled by sedimentary faces,nose-shaped uplift is important for oil enrichment. |
| Keywords: | Xizichuan Chang 9 Chang 8 subtle accumulation law |
