沧东凹陷孔二段致密储层特征及分布规律

摘要

沧东凹陷孔二段湖盆中心有机质丰度高，生烃能力强，资源潜力大，是致密油勘探的重点层系。钻探证实该区包括泥页岩类、白云岩类、致密砂岩三大岩类，储层特征不同。以钻井取心资料岩性识别为基础，利用散点图技术测井技术进行岩性的识别，初步明确致密储层的展布规律，对该区勘探方向和目标选择具有重要指导意义。%Lake basin The center of Kong 2 formation with withcontains high abundance of organic matter., hydrocarbon generation ability,The resource potential wasas confirmed by drilling that it has three types of rock, which included mud shale, dolomite, and dense sandstone., and reservoir characteristics are different. Based on the lithology identification by drilling coringe data and applicaition of logging technology by the scatterplot technique, the distribution regulation of dense reservoir it is was preliminarily clarifiedear for distribution law of density reservoir,. and iIt iwas important significant for the exploration direction and the target selection.
