| 摘 要： | 南山坪背斜位于扬子板块中部，核部上震旦统含有大量沥青，是一个被破坏的古油藏。笔者通过建造分析认为震旦纪至中三叠世属于古隆起发育阶段，进一步划分出震旦纪古隆起雏形期、早古生代古隆起保持期和晚古生代—中三叠世古隆起发展期。晚三叠世至新生代属于断裂褶皱发育阶段，进一步划分出晚三叠世—中侏罗世宽缓背斜发育期、燕山运动Ⅱ幕断展背斜发育期、燕山晚期和喜玛拉雅期背斜改造期。南山坪古油藏以上震旦统灯影组白云岩为储层，以上覆下寒武统牛蹄塘组黑色碳质泥岩和石煤为烃源岩，志留纪至中三叠世古隆起聚集油气，晚三叠世至中侏罗世是油气再分配和南山坪古油藏形成时期，之后是古油藏被破坏时期。

| Abstract: | The Nanshanping anticline, located in the center of the Yangtze plate, is a destroyed ancient oil accumulation. The upper Sinian in the core of the anticline contains large amount of bitumen. Based on an analysis of the sequence of strata, the authors propose that the Sinian to Middle Triassic was a period of paleo-uplift development, which may be further divided into the Sinian embryonic paleo-uplift stage, Early Paleozoic paleo-uplift conservation stage and Late Paleozoic to Middle Triassic paleo-uplift development stage. Analysis of modification suggests that the period from the Late Triassic to Cenezoic was a period of the development of faults and folds, which may be subdivided into the stage of Late Triassic-Middle Jurassic broad anticline development, stage of fault propagation and anticline development in the II phase of the Yanshanian movement and stage of late Yanshanian and Himalayan anticline modification. The Nanshanping ancient oil accumulation takes dolomitite of the upper Sinian Dengying Formation as the reservoir and black carbonaceous mudstone and stone coals of the overlying Lower Cambrian Niutitang Formation as source rocks. Oil and gas were accumulated in the paleo-uplift from Silurian to Middle Triassic. The Late Triassic and Middle Jurassic witnessed the redistribution and formation of the Nanshanping ancient oil accumulation. Later the ancient oil accumulation was destroyed. |
