馆下段岩性油藏研究——以陈家庄凸起东段为例
|
摘要
馆陶组是整个济阳坳陷的主力含油层系,但内部各区块在馆陶组成藏机理不尽相同。陈家庄凸起东部馆陶组油藏是在超覆背景下成藏的岩性油藏,具有一定的代表性。凸起东段馆下段砂组砂体横向变化快,砂体构造高部位含油,含油高度低,平面上呈窄条带状分布,地震解释和资源评价有一定难度。对陈家庄凸起东段馆下段构造演化、地层、沉积、储层、成藏特点、油气分布特征等进行了综合研究,归纳出适应本区实际的定量描述方法,丰富了济阳坳陷馆下段成藏模式。
Guantao Formation is the main hydrocarbon reservoir assemblage,but the reservoir forming mechanism of each block is not exactly same in Guantao Formation.The lithologic oil pools of Guantao Formation in the east of Chenjiazhuang Uplift formed under the background of overlap has a certain degree of representativeness.The sand bodies in the lower Guantao Formation of the east of Uplift changes rapid horizontally,the high localizations of the sand body are oil-bearing,the oil-bearing altitudes are low and show narrow longitudinal zonality,which is difficult to be interpreted and evaluated.The features of the structural evolution,layer,deposit,reservoir and reservoir forming and the oil and gas patterns of the lower Guantao Formation of the east of Uplift are researched comprehensively,some quantitative description methods for Chenjiazhuang area are induced,and the reservoir forming patterns are increased.
