摘要/Abstract

摘要： 随着油气地球化学实验技术和方法的发展,利用储集层沥青的饱和烃色-质图的指纹特征识别流体类型已经得到较大范围的应用。但这一方法在高演化地区的气层识别上遭遇到一些问题。从高演化地区储集层特征进行分析,提出了高演化地区储集层中存在两种赋存状态的可溶储集层沥青——游离态和束缚态。根据对储集层中这两种可溶储集层沥青的识别,结合前人研究的地球化学方法识别油、气、水层的基本原理,成功地对高演化地区的气层、非气层进行了识别,为天然气的勘探前景评价和开发方案的制定提供了科学的依据。

Abstract: The fingerprint characteristics on mass-chromatograph chart of saturated hydrocarbon extracted from reservoir bitumen is widely used to identify reservoir fluid types, with the development of technology and method of petroleum geochemistry. However, the reservoir fluid type in high-evolution area can't be exactly identified with this method. Based on analysis of the reservoir feature in high-evolution area, a new reservoir bitumen classification is suggested. In view of the soluble ability in the organic solvent, the reservoir bitumen in high-evolution area can be divided into two types of soluble reservoir bitumen, one is in free state and the other in included state. The identification of these two soluble reservoir bitumen is integrated with the available geochemistry methods for recognizing oil, gas and water zones/layers, hence proper identification of gas-bearing formation and non-gas-bearing formation in the high-evolution area is exactly made, providing sound scientific basis for development scheme preparation and prospect evaluation of natural gas exploration.
