摘要：

将GeoX软件应用于十屋断陷太平庄构造勘探目标,主要进行了地质风险分析、油气资源量计算和经济评价,具体包括:(1)对营城-登娄库组和泉头组勘探层的边缘概率、有效储层概率(P1)、有效圈闭概率(P2)、有效源岩及油气聚集概率(P3)、有效保存概率(P4)分别赋值,可分别得到两套储层的油气发现概率0.192和0.201,由此判定太平庄构造的勘探属中等地质风险范畴;(2)选取圈闭面积、储层厚度、几何形态、有效孔隙度、圈闭充填率、含油气饱和度等12项参数,通过计算获得目标构造的地质资源量为291×104t,可采资源量为66×104t,属小型油气田,资源丰度偏低;(3)最后对勘探目标进行经济评价。现已探明太平庄构造的石油地质储量为76×104t,与GeoX软件计算结果近似。

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.
