储量参数的选取方法直接影响油气储量评估结果的精确度。井点面积权衡法以三角剖分为基础，是计算储量参数平均值的重要方法。基于 Delaunay 三角剖分构建 Voronoi 图计算单井控制面积的方法，在钝角三角形中存在“真空”面积，影响了储量参数的计算；改进 Voronoi 图计算单井控制面积的算法，克服了“真空”面积的存在，提高了计算结果的可信度；针对不同的储量参数，在改进 Voronoi 图计算单井控制面积的基础上，采用井点面积权衡法、岩石体积权衡法和孔隙度体积权衡法模型，符合油气区域立体空间特征，为储量计算提供更可靠的储量参数。

The selection method of reserves parameter directly affects the accuracy of assessment results of oil and gas reserves.The well point area weighting method,based on triangulation,is an important method to calculate the average val-ue of the reserves parameters.The method based on Delauney triangulation to construct Voronoi diagram for calculating the single well control area impacted calculation of the reserves parameters due to the existence of a "vacuum"in an obtuse triangle.The algorithm of the improved Voronoi diagram for calculating the single well controlled area reduces the "vacu-um"area presence,and improves the credibility of the calculation results.Aiming at the different reserve parameters,on the basis of the improved Voronoi diagram for calculating the single well controlled area,models of well point area weigh-ting method,the rock volume weighting method,and porosity volume weighting method were used to reflect the three -di-mensional space characteristics of the oil and gas area.This provides more reliable parameters for reserves calculation.
