摘 要:针对海坨子地区勘探存在沉积体系、沉积相带及砂体展布对油气控制因素不清等问题 ,综合利用岩心、录井、测井、地震和各类化验分析资料 ,采用现代沉积学、层序地层学的研究方法 ,对海坨子地区姚家组二、三段开展沉积微相精细研究 ,搞清了骨架微相砂体类型和几何形态 ,总结了不同时期沉积微相平面时空演化规律 ,确定岩性尖灭带位置 ,分析沉积相带对油气的控制作用 ,指出有利油气聚集相带及优质储层发育带 。Sedimentary facies, sandbody distribution and their control over oil and gas accumulation in the second and third members of the Yaojia Formation in Haituozi area, the Songliao Basin were poorly understood during the process of exploration. In order to solve these problems, the authors deliberately studied sedimentary microfacies, the types of main sandbodies and their distribution in this area by using modern sedimentary and sequence stratigraphy and on the basis of core, logging, seismic and related experimental data. Also, the evolution of sedimentary facies and their control over oil and gas accumulation was summarized, and the pinch out position of sandbeds and advantageous reservior zones were pointed out. All these provided technical supports to looking for blind reservoirs in this area.
