油气输导体系研究综述

Review of research on oil and gas transport system

输导体系作为纽带连接着烃源岩和圈闭,对其进行刻画,一方面可以确定油气运移路径,另一方面可以准确定位油气藏的位置,重要性不言而喻。本文在介绍输导体系基础的概念、特征和分类的前提下,还对优势运移通道的确定、输导能力定量判断方法以及所起的控藏作用进行了详细分析。总结了输导体系的研究方法与存在需要解决的问题,研究方法分别从地质分析、物理模拟和数值模拟三方面进行论述,对于未来的发展提出应该使所用参数与所处时期相对应,加强对输导效率的研究,重视三维动态的展示,以及与多个学科联动结合发展。

The transport system,serving as the link connecting source rocks and traps,plays a pivotal role in characterizing hydrocarbon migration.On the one hand,delineating the transport system helps determine oil and gas pathways,while on the other hand,it facilitates the accurate positioning of hydrocarbon reservoirs,underscoring its undeniable importance.This paper,after introducing the fundamental concepts,characteristics,and classifications of the transport system,provides a detailed analysis of determining dominant migration pathways,quantitative assessment methods for transport capacity,and the reservoir-controlling effects of the transport system.The study concludes by summarizing research methods and identifying outstanding issues for resolution.The research methods encompass geological analysis,physical simulation and numerical simulation,addressing the necessity to align parameters with corresponding geological periods,emphasizing the study of transport efficiency,highlighting three-dimensional dynamic representations,and advocating interdisciplinary collaboration for future development.
