Oil and gas source and reservoir characteristic of Fuyu Reservoir of Chaochang area in north Songliao Basin
摘要
Abstract
Oil and gas origin of Fuyu oil layer of Chaochang area was analyzed, characteristics of hydrocarbon were summed up, and favorable exploration areas of Reservoir of Chaochang area were forecasted during synthetical studying, which provided theory support for exploration. Oil and gas origin was analyzed by the research of hydrocarbon source rocks evaluation and the oil-source rock correlation. The Fuyu layer Reservoir-forming characteristics was studied by resuming the fluid potential and analysis, hydrocarbon transporting system, oil-water relationship, reservoir types and main controlling factors of hydrocarbon accumulation. The research displays that the crude oil of Fuyu layer in Chaochang area is mainly coming from Sanzhao and Binxian-Wangfu Depression's mature source rock which are high fluid potential Field. Fluid potential indicates that Chaochang area is lower Fluid Potential Field. It is benefit to the oil and gas migration to this area by sand (north-east direction) and default zone (south-north direction). The oil and water analyses display that the oil is in the upper of Reservoir and the water is in the lower of Reservoir, pressure difference between Source Rocks with Reservoirs decides oil column height, positive tectonic controls oil and gas accumulation. The fluvial channel sand is efficacy reservoir, and controls the distribution of oil and gas. The Fuyang reservoir type has tectonic, lithologic-tectonic, lithologic, default-lithologic and tectonic-lithologic oil pool. There are two types of Patterns of Hydrocarbon, one is the near source over pressure, the source over the reservoir, short distance, vertical-migration; the other is near source constant pressure-negative pressure middle distance across the range migration.关键词
