青东凹陷沙三段、沙四段储层生油潜力与油气分布规律研究

青东地区是胜利油田勘探程度较低的地区之一,基于该区地层发育特征认识不足以及油气分布规律不明朗等问题,首先在构造、油藏类型、测井和地质资料基础上对研究区发育形态位置进行剖析,在明确了青东地区地层发育特征的基础上,结合烃源岩热分解资料,对该区烃源岩进行了研究,通过分析已钻井热解数据找出主要油源层以及生油潜力区,从绘制的沙四上亚段暗色泥岩等厚图和沙三下亚段暗色泥岩等厚图可以得到砂体在平面的上分布规律,进而初步确定了该区烃源岩特征以及油气在横、纵向上的分布规律,研究结果有利于对青东凹陷进行深入挖潜,为后续勘探开发提供地质依据。

Genetic Potential and Distribution in the Es3 and Es4 of Qing-dong Sag Reservoir

green east region is one of the areas of shengli oil field exploration degree is low, based on the formation and development characteristics of insufficient understanding and oil and gas distribution regularity of uncertain problems, first of all in structure, reservoir types based on the geological data, well logging, and analyzes the position and development in the studied area form in the clear blue east region on the basis of the formation and development characteristics, combined with the hydrocarbon source rock pyrolysis data, studied the hydrocarbon source rocks in the area, through the analysis has drilling pyrolysis data to find out the main oil source layer and genetic potential area, drawn from four on the section through the dark mudstone isopach map and sand under the three period of dark mudstone isopach map can be on the plane distribution of sand body, and preliminarily determines the characteristics of the hydrocarbon source rocks and oil and gas in the horizontal, vertical distribution, the results of the study is beneficial to to an in-depth exploration of east sag, provide geological basis for further exploration and development.
