长期以来,含油性常常被认为是划分油气层的主要尺度。然而实践表明,单纯依据含油(气)饱和度很难对油气层作出完善的解释。因为,含油性毕竟只是产层静态特性的反映,不能完整描述储集层产油气的动态规律。事实上,只有从油层物理的基本概念出发,以油、气、水在微观孔隙中的渗流理论为依据,才能建立评价油气层完整的测井解释理论。针对这一目的,本文以油层物理学为基础,通过分析油、气、水在微观孔隙中的分布和渗流规律,比较系统论述了划分油气层的基本原理和影响油气层界限的因素,进一步阐明评价油气层所应遵循的途径。这样,不仅为测井分析和方法研究提供了比较完备的解释理论,而且也标志着一种以产层动态概念为依据评价油气层的新型解释方法,有可能投入现场的实际应用。
For a long time, oiliness was often considered as the main criterion for the division of oil and gas layers. However, practice shows that it is very difficult to make a complete explanation of the hydrocarbon layer based solely on the oil (gas) saturation. Because, after all, oil is only a reflection of the static characteristics of the production layer, can not be a complete description of the dynamic laws of oil and gas production in the reservoir. In fact, only from the basic concept of reservoir physics, based on the seepage theory of oil, gas and water in micro-pores, can we establish a complete logging interpretation theory to evaluate the hydrocarbon reservoir. For this purpose, based on reservoir physics, this paper systematically discusses the basic principles of the division of oil and gas reservoirs and the factors that affect the boundaries of oil and gas by analyzing the distribution and seepage laws of oil, gas and water in the micro-pores. The way to evaluate the oil and gas layers. In this way, it not only provides a comparatively complete interpretation theory for well log analysis and methodological research, but also marks a new interpretation method for evaluating oil and gas layers based on the dynamic concept of the payzone and may be put into practical application in the field.
