孤岛油田新第三系中新统上馆陶组储集层为河流相沉积,其中上部3、4油层组为蛇曲河流沉积,下部5、6油层组为网状河流沉积。本文从岩性、沉积构造、测井曲线、粒度概率曲线及 C—M 图、古生物、主要古水文参数、砂体形态和砂体的非均质性等方面对两种河流沉积的不同性质作了论述。本文还从油水运动速度、含水上升率、水淹孔隙体积和最终采收车等方面对开采规律进行了探讨。 The Guantao Formation reservoir in the Neogene of the Gudao Oilfield is fluvial facies sedimentation, in which the upper part of the 3rd and 4th member reservoirs are serpentine and the lower 5 and 6 reservoirs are reticular river sediments. Based on lithology, sedimentary structure, well logging curve, probability curve of grain size, C-M diagram, paleontology, main paleo-hydrological parameters, sand body morphology and sand body heterogeneity, The discussion. In this paper, the mining law is also discussed from the aspects of the speed of oil and water movement, the rising rate of water cut, the pore volume of flooding and the final harvester.
