辽河东部铁匠炉斜坡带构造特征及其对岩性油气藏控制

Structural Characteristic and It's Control to Lithological Reservoir in the Tiejianglu Slope Belt,Eastern Liaohe Depression

断陷湖盆的斜坡带结构特征复杂、变化快,不同的断陷湖盆斜坡带结构特征各不相同。斜坡带位置、古地貌背景以及地层、沉积、构造条件的差异,造成相应油气成藏特征的不同。利用坡折带理论分析斜坡带结构特征,进而划分斜坡带,有助于对岩性油气藏形成分布规律的研究。以坡折带理论为指导,对辽河油田东部铁匠炉斜坡带结构特征进行综合研究,分析其成藏特征,确定了斜坡带构造对岩性油气藏的控制作用。

The structure characteristic is complex and changed quickly on the slope of the faulted lake basin, it has to be various structure characteristic that in different faulted lake basin. The difference of the position of slope, the paleogeomorphology background as well as the stratum, the deposition and the structural environment, creates the corresponding difference characteristic of oil and gas. On the basis of the slope break theory, it is helpful that the analysis and division on the slope structure belt characteristic to the distribution of the lithological oil and gas pool. The synthetic analysis have been studied about the structure characteristic on the Tiejianglu slope zone of the Eastern Liaohe depression, it is confirmed that the control to lithological oil and gas pool.
