摘　　要：古龙油田是松辽盆地最典型的向斜油藏，利用岩心、录井和测井等基础资料，从宏观和微观2方面研究了古龙北向斜葡萄花油层的油气富集规律。研究结果表明，断裂、沉积微相和地层压力因素为其宏观控制因素，而沉积韵律、砂体连通性和储层物性等微观因素对油水层的分布也起到一定的控制作用。结合储层厚度、物性、试油产量等资料，将全区分为3类有利区块并优选，合理安排动用次序，为古龙北油田向斜区葡萄花油层下一步的勘探与开发提供了依据。Gulong Oilfield is the most typical syncline reservoir in Songliao Basin. With the help of the basic data such as core, logging and well logging data and so on, the petroleum enriched laws in Putaohua reservoirs of North Gulong syncline are studied from macroscopieal and microcosmic respects. The researches show that the fracture, sedimentary microfacies and formation pressure are macrocontrolling factors, and the micro factors such as sedi mentary rhythm, sand body connectivity, physical properties of the reservoirs and so forth possess a certain control ling actions on the distribution of oil and water layers. Combined with the data of reservoir thickness, physical prop erties, oil test production and so on, the Whole block can be divided into three types of favorable belts and opti mized further, finally the reasonable developed order is selected and wellarranged, thus the achievements obtained above have provided the foundation for further exploration and development of Putaohua oil reservoirs in the syncline zone of North Gulon~ Oilfield.
