摘要:
为确定霍尔果斯背斜紫泥泉子组油气藏气侵作用及其主控因素,利用油气地球化学性质分析、包裹体测试、地震等方法,对该区块发生气侵分馏作用的油气藏进行研究,分析了气侵分馏作用对油气藏的影响。研究表明,研究区有机质丰度高,具有持续生气的能力;数量众多的断裂以及油气充注时间等地质条件匹配良好,使油气藏发生大规模气侵分馏作用;地层压力和垂向深度是控制气侵分馏作用强度的主要因素;气侵分馏作用是导致该油气藏形成稠油、低蜡质凝析油和高蜡质油等复杂原油类型的直接原因。
Abstract:
In order to identify the gas invasion and its main controlling factors in the oil and gas reservoirs in Ziniquanzi formation of Horgos anticline, using the methods of geochemical property analysis, inclusion testing and seismic analysis, this paper studies the oil and gas reservoirs in which fractionation of gas invasion occurs, and analyzes the influences of the fractionation on the reservoirs. The study result shows that the source rocks have high organic matter abundance and persistent gas generation capability; a large number of faults and a good matching of geological conditions such as oil and gas charging time in the study area cause the large scaled gas invasion fractionation in the study area; formation pressure and vertical depth are the main factors controlling the intensity of gas invasion fractionation; the gas invasion fractionation is the direct cause of the formation of complex crude oil types such as heavy oil, low waxy condensate oil and high waxy oil
