The Geological Conditions Of Oil And Gas In Turpan Hami Basin Zone Evaluation

After more than ten years exploration of tuha basin,overall exploration degree is higher,in the past to emphasizes the longitudinal on the classification of petroleum system,reservoir and caprock,ignoring the conditions for hydrocarbon range,in the plane of the petroleum system wasn't up to the oil and gas resources,provides the optimal evaluation units and puts forward the aim of the favorable oil and gas accumulation zone.This paper want to complete the division of basin oil and gas system through the analysis of the basin,to evaluate the different system of oil and gas exploration value,the research on the rules of hydrocarbon accumulation,the favorable exploration direction and zones of oil and gas,optimizing exploration direction.This paper on the basis of the theory of source control,from mature hydrocarbon source rock distribution for the baseline,petroleum system of tuha basin,based on the petroleum geological characteristics of tuha basin and the analysis of the forming process,the petroleum system framework,determine the critical time and oil and gas filling mode,summarizes oil accumulating regularity.In different types of reservoir dynamic accumulation process analysis,based on the established different types of reservoir accumulation mode.The patterns according to different analysis to major and minor controlling factors.Basin is favorable area of oil and gas migration and favorable exploration zone forecast,according to the basin,the main direction of oil and gas migration,combination of oil and gas resources evaluation results on the analysis of basin petroleum system mainly to oil and gas migration,pointing out favorable zones for oil and gas could enrichment in the end.The geochemical characteristics of crude oil and hydrocarbon source rock,crude oil types,analysis of oil source.System of oil field the main reservoir anatomy,based on section tectonic evolution recovery,using the method of reservoir geochemistry,fluid inclusions,analysis method and the hydrocarbon source rock evolution method for inversion of oil and gas accumulation periods and accumulation process,determine the main accumulation stages of oil and gas,clear the dynamic process of hydrocarbon accumulation accumulation model is established.According to different types of typical characteristics of reservoir,combined with the accumulation mode,analysis as the main control factors,points out that the favorable oil area.
