| 摘 要： | 通过对鄂尔多斯盆地三叠系延长组的构造条件、烃源条件、储层条件、储盖组合和保存条件等方面的详细分析,认为该区延长组具有优越的成藏条件,具有形成良好油藏的潜力.油藏控制因素分析表明:油藏分布受延长组烃源岩厚度、生烃强度、排烃强度控制,油气运移指向紧邻生烃坳陷的流体低势区;有利沉积相带是三角洲油藏形成的基本地质条件,三角洲前缘亚相中的水下分流河道往往距生烃坳陷近,具有优先捕获油气的位置优势,是油气富集的最有利场所;高渗透储层是油藏高产的重要因素.盆地中长6、长8地层中存在相对高渗透砂岩储层,油藏的高产往往与其有直接的关系.

| Abstract: | The reservoir-forming conditions and the main controlling factors are the most important questions confronted by oil exploration in the oil-gas-bearing basin.By the detailed analysis of many aspects of the Upper Triassic Yanchang Formation in Ordos Basin,such as the structure conditions,hydrocarbon source conditions,reservoir conditions,the conditions storing-cover combination up and the conditions of preservation,the authors think that there are the superior oil formation conditions and the fine potential ... |
