彰武断陷九佛堂组资源潜力

Resource Potential of Jiufotang Formation in Zhangwu Fault Depression

彰武断陷为江汉流转新区,为进一步弄清其资源潜力及勘探价值,利用Trinity软件,借助其在三维数据处理、各项参数运算、油气运聚及资源量计算等方面优势,在新钻井及烃源岩重新认识的基础上,运用烃源岩生烃动力学理论和方程,将烃源岩的面积、厚度、原始TOC等参数带入运算,以此得到烃源岩的生、排烃量和总资源量分别为85.25×10^(6)t、55.09×10^(6)t和58.22×10^(6)t,明确了该区依然是下步油气勘探的重点地区。

Zhangwu fault depression is a newly-transfered concession area in Jianghan Oilfield.In order to further clarify its resource potential and exploration value,we used the Trinity software and its advantages of 3 D data processing,algorithm of various parameters,calculation of resource reserves and hydrocarbon migration and accumulation,and also applied the theory of dynamics of generation of the hydrocarbon source rock and equation to calculate its area,thickness,original TOC,original HI,maturity,crude oil adsorption coefficient,hydrocarbon migration and accumulation coefficient of source rocks,the efficient of hydrocarbon migration and accumulation generation and so on,so as to obtain its quantity of hydrocarbon generation and expulsion and its total resources of 85.25×10^(6)t,55.09 ×10^(6)t and 58.22 ×10^(6)t,respectively,on the basis of the renewed insight of the newly-drilled wells and hydrocarbon source rocks.It is clear that this area is still prioritized for the next oil and gas exploration.
