摘要
储层预测和油藏描述方法技术已经在油气资源勘探开发工程中发挥着日益重要的作用。然而 ,在重视其方法进步与技术创新的同时 ,更要注重其丰富的石油地质学内涵。特别是研究对象为岩性、地层等隐蔽油气藏时 ,其核心内容涉及到沉积地质学的诸多理论问题。基于此因 ,本文针对我国陆相盆地河流 -三角洲 -湖泊沉积体系中岩性油气藏的特点 ,对储层预测和油藏描述中一些诸如 :研究对象的背景及其地质基础 ;油气藏的储层相构形描述 ;三角洲前缘储层的成因类型及其描述 ;小尺度岩相制图、成藏要素及目标优选以及以流动单元为对象的储层三维构形研究与油藏描述等沉积地质学的问题给予了阐述。强调储层预测和油藏描述技术离不开沉积地质学这一根本基础。
Techniques and methods used forprediction of reservoirs and description of pertoleum accumulation have important effect in exploration and exploitation of engineering of oil and gas resource. However, their more abundant base connotations are taken into account when advancement of method andinnovation of technique are paid attentionto. Especiallywhen the research objects are hiddenpetroleum accumulations such as lithologic and strata reservoirs, their core contents refer to theory problems of sedimentary geology. So,in this paper it aimsat the peculiarity of lithologic reservoirs of sedimentary system of fluvial-delta-lacutrine of terrigenous basin in our country, many sedimentary geologicalproblems in prediction of reservoirs and description of pertoleum accumulation are expounded. These problems include the background and geological basement of research objects, the description of reservoir facies architecture of pertoleum accumulation, genetic types and their description of reservoir at delta front, petrographical facies mapping on small scale, elements of reservoir formation and high grade target and the research of reservoir three dimensionalarchitecture taking the reservoir flow units as objects, and it emphasizes that techniques of prediction of reservoirs and description of pertoleum accumulationare dependent onsedimentary geology,which is the fundamental basis.
