Structural Characteritics and Hydrocarbon A ccumulation in Dongwan A nticline

Abstract

Abstract: Dongwan anticline is located in the southern margin of Junggar basin with better source, reservoir and cap rocks. Is structures were proved by multi-demonstration with many geophysical and geological methods. However, there was no oil-gas indication from Dongwan-1 Well that was completed in 2003. In-depth understanding of the southern margin regional setting is made, the structural evolution, shape mechanism and hydrocarbon accumulation conditions are discussed, and the oil-gas accumulation pattern is summarized. Finally, two types of petroleum accumulation/reservoir models possibly existed in Dongwan area is presented in this paper.

Key words: Junggar basin, structure, anticline, feature, hydrocarbon accumulation
