Reservoir-processing analysis and the development of pressure in Upper Paleozoic of Ordos Basin
Journal Title: Science Paper Online - Year 2008, Vol 3, Issue 11
Abstract
This article takes a dynamic analysis, comprehensive research and theory of basin forming, hydrocarbon generation and hydrocarbon accumulation. Through the detailed analysis about sedimentary burial history, hydrocarbon-generating history, diagenesis history, geothermal history and combining with the synthetic analysis on compacting characteristic of the sandstone and mudstone, history of pressure origin and inclusion analysis et al. Analyzing history of pressure origin and evolution and reservoir-processing in upper Paleozoic of ordos basin. From this article we think the relationship between history of pressure origin and evolution and reservoir-processing in upper Paleozoic of ordos basin, pressure as dynamic of gas migration and forming having great influence on gas pool forming in upper Paleozoic. Through analyzing of temperatures and pressure, laster Raman spectra, we compartmentalize pool forming period of different gas reservoir type, put forward three key phases about pressure evolution and reservoir-processing: forming primary gas reservoirs in loading pressure, burial stage; forming primary gas reservoirs in unloading and decompression, denudation of ascending stage; forming secondary gas reservoirs in adjusting and decompression, stabilization stage. The importance of tectonic uplift to gas pooling in upper Paleozoic after the K1 phase is especially emphasized. It is abvious differently forming pressure among nonsource rock, source rock and sand in pressure compartment, having different influence reservoir-processing in gas pool upper Paleozoic. Through particularly analyaing of six courses about forming pressure and reservoir, pressure and pooling evolution models are established in upper Paleozoic of ordos basin.
