底层对比方法及应用.doc

摘要 地层的划分和对比是最基础的地质工作，其主要目的是建立地层层序。在地层研究工作中，确定一个地区地层层序主要涉及对这一地区的地层的正确划分，而确定一个地区与相邻地区地层层序的相互关系，则将涉及不同地区之间的地层对比问题，实际上地层的划分和对比二者是不能截然分开的。? 油气藏开发阶段的地层划分与对比，是在油气藏发现以后进行的研究工作，它所要解决的地层问题是为了满足大比例尺地质制图的需要。因此，层组的划分与对比是开发阶段油藏描述最基础的工作之一，只有合理地划分层组，才能正确揭示层间非均质，正确实施分层开采的各项措施。正确的等时对比才能搞清各级层组的空间变化规律。对储层认识的精细程度和可靠程度取决于层组划分的精细程度和对比的可靠程度。 [关键字]: 油气藏；地层；精细 Abstract Stratigraphic classification and correlation of geological work is the most basic, its main purpose is to build the stratigraphic sequence. In the formation of research work, determine the stratigraphic sequence in a region mainly relates to the correct division of this region of the formation, and to determine the relationship between the stratigraphic sequence in a region and adjacent areas, will involve stratigraphic correlation problem between different regions, in fact, stratigraphic division and comparison of the two can not be separated. Stratigraphic division and correlation of oil and gas reservoir development stages, is found after the research work in oil and gas reservoir, stratigraphic problems it should solve is to meet the needs of large scale geological mapping. Therefore, division and correlation of layer group is the development stage of reservoir description is one of the most basic work, only the reasonable partition layer group, can correctly reveal the interlayer heterogeneity, the correct implementation of various measures of slice mining. Comparison to find out various layer group spatial variation of the right. Reliability of fine degree and contrast the understanding of reservoir fine degree and degree of reliability depends on the layer division.
