油气沉积学原理及其在勘探开发中的应用

本文以油气藏形成条件中的生、储、盖、运、圈为纲讨论了油气勘探沉积学;以油气藏开发过程中与沉积、成岩的关系讨论了油气开发沉积学。在油气勘探沉积学中重点论述了陆相沉积与储层及圈闭的关系;在油气开发沉积学中重点论述了储层研究的基础—储层的沉积属性和成岩特征。强调储层沉积、成岩研究应成为储层评价最重要的内容。

PRINCIPLES OF HYDROCARBON SEDIMENTOLOGY AND THEIR APPLICATIONS IN EXPLORATION AND DEVELOPMENT OF HYDROCARBONS

In framework of essential conditions required for formation of a hydrocarbon bearing reservoir, including hydrocarbon generation, accumulation and preservation, barrier sealins, migration and trapping, the hydrocarbon explo-ration sedimentology is discussed. The discussions of hydrocarbon development sedimentology are made based on therelationship among sedimentation, petrogenesis and developing process during development of hydrocarbon reser-voir. In hydrocarbon exploration sedimentology,it's discussion is focused at the relationships among terrestrial sedi-mentary facies, reservoir beds and traps. In hydrocarbon development ,sedimentology,it's discussion is focused at sedimentary attributes and petrogenic characteristics, both are the foundation of reservoir study, and particularly empha-sised that the studies of reservoir sedimentology and petrogenesis process should be treated as most important content.
