河流比较沉积学与河流砂岩油藏开发

Comparative Sedimentology and ReservoirDevelopment of Fluvial Sand Bodies

在比较沉积学理论的基础上对古现代河流类型及其沉积特征、影响因素进行研究、比较和归纳，以现代河流沉积学的研究成果对比研究了古代不同类型河流成因的沉积岩的沉积特征、砂体形态及其孔渗特征，从而为河流砂岩储层中油气的勘探和开发提供依据．

ased on the principles of comparative sedimentology and processresponse sedimentation model, this paper presents the subdivision of fluvial types, depositional models, sedimentary characteristics and influencing factors in modern rivers, which are conductive and the main topics concerned in reservoir study. Combined with the geological case history in modern rivers, the paper explorates the general analysis of development problems of the studied reservoirs in ancient time, including sedimentary characteristics, sand body geometry and the features of porosity and permeability, meanwhile, the case studies are given as the geological bases in the study of petroleum exploration and development.
