本文提出的方法适用于预测探区中的含油气有利地带,对确定钻探井位有实际意义。方法的要点是把已有的各种地质资料作为指导寻找油气的地质信息。按这些数据间的关系,分成基础地质数据及组合地质因素。用平面插值法计算得到每种基础地质数据的分带图。把这些同类数据分带图叠合起来而得到组合地质因素的评价含油性分带图。最后再把不同的组合地质因素分带图叠合起来而得到探区的预测含油气有利地带的评价图。经生产上的实际应用,说明本文提出的方法是可行的。
The proposed method is suitable for predicting the hydrocarbon-bearing favorable zone in the exploration area and has practical significance for determining the drilling well location. The main point of the method is to use the existing geological data as a guide to find the geological information of oil and gas. According to the relationship between these data, divided into basic geological data and the combination of geological factors. The zonal map of each basic geological data is calculated by plane interpolation. The same type of data zonation is superimposed to obtain a combined geological evaluation of the oily zonation. Finally, the different combination of geological zonation maps are superimposed to get the prospective oil-gas zone of the exploration area. The practical application shows that the method proposed in this paper is feasible.
