Petroleum Exploration of Craton Basins in China

Petroleum Exploration of Craton Basins in China Abstract Craton basins are a significant petroliferous provenance. Having undergone multiple open‐close tectonic cycles and strong reworking of the late Cenozoic tectonic movement, the craton basins in China are highly broken. This has resulted in multi‐source and multiphase hydrocarbon generation and later hydrocarbon accumulation so that a complicated spatial assemblage of primary, para‐primary and secondary oil‐gas pools has been formed. The primary factors controlling hydrocarbon accumulation include hydrocarbon‐generating depressions, paleouplifts, paleoslopes, unconformity surfaces, paleo‐karst, faults and fissure systems as well as the later conservation conditions. In consequence, the strategy of exploration for China's craton basins is to identify the effective source rocks, pay attention to the different effects of paleohighs and late reworking, enhance studies of the secondary storage space, attach importance to the exploration of lithologic oil‐gas reservoirs and natural gas pools, and approach consciously from the secondary oil pools to the targets near the source rocks. At the same time, a complete system of technologies and techniques must be built up. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Geologica Sinica (English Edition) Wiley

Abstract

Abstract Craton basins are a significant petroliferous provenance. Having undergone multiple open‐close tectonic cycles and strong reworking of the late Cenozoic tectonic movement, the craton basins in China are highly broken. This has resulted in multi‐source and multiphase hydrocarbon generation and later hydrocarbon accumulation so that a complicated spatial assemblage of primary, para‐primary and secondary oil‐gas pools has been formed. The primary factors controlling hydrocarbon accumulation include hydrocarbon‐generating depressions, paleouplifts, paleoslopes, unconformity surfaces, paleo‐karst, faults and fissure systems as well as the later conservation conditions. In consequence, the strategy of exploration for China's craton basins is to identify the effective source rocks, pay attention to the different effects of paleohighs and late reworking, enhance studies of the secondary storage space, attach importance to the exploration of lithologic oil‐gas reservoirs and natural gas pools, and approach consciously from the secondary oil pools to the targets near the source rocks. At the same time, a complete system of technologies and techniques must be built up.
