Abstract:

During the exploration in Taipingzhuang structure,the GeoX software has mainly be applied to make geologic risk analysis,estimation of hydrocarbon resources,and economic evaluation.(1)Through setting valuation on marginal probability,and probabilities of effective reservoir (P1),effective trap(P2),effective source rock and hydrocarbon accumulation (P3) and effective preservation(P4) in both exploration targets,Yingcheng Formation and Quantou Formation,the finding probabilities in the two reservoir sets have been calculated to be 0.192 and 0.201,respectively.It can then be judged that the exploration in Taipingzhuang structure would be in the category of moderate geologic risk.(2)Giving the 12 parameters,including trap area,reservoir thickness,geometric configuration,effective porosity,trap's fillup efficiency,oil/gas saturation,etc,the resources in place and recoverable resources in the target structure can then be estimated to be 2.91million tons and 0.6 million tons,respectively.It should be of small field with rather low abundance.(3)Lastly,economic evaluation of the exploration target has been made.The geologic reserves in Taipingzhuang structure has now been proved to be 0.76million tons of oil,very similar to the estimating result made with GeoX software.
