Abstract
According to the character of secondary hydrocarbon migration of a general model and on the basis of a large amount of sampling test data, this paper adopts the dynamic analysis and synthetical study method combining dynamic state with static state and combining single item with multiple items to study the characteristics of secondary hydrocarbon migration in the Malang sag of the Santanghu basin of Xinjiang. By analysing a large amount of hydrocarbon expulsed from Upper Permian Lucaogou Formation muddy source rocks matured in Late Jurassic, there are two key episodes of oil and gas accumulations recognized in the study area, including the ends of Early Cretaceous and Late Cretaceous. The faults, unconformity surfaces, fractures and communicating formations can serve as migration pathways, and the dominant way of hydrocarbon migration and accumulation is vertical and short distance migration in the hydrocarbon source region and lateral migration is a subsidiary way. The major characteristics of secondary hydrocarbon migration modes in the Malang sag are that anticline, faulted anticlines and lithologic type are the dominant migration modes in Mesozoic-Cenozoic Erathem, and that fault block, fault terrace and stratigraphic type are the dominant ones in Late Paleozoic. The practice indicates that the pattern of secondary hydrocarbon migration is of important significance for petroleum exploration.关键词
