摘　　要：探明未动用储量的地质的复杂性,决定了其经济评价的难度。为此,在对地质风险评价时,选取了有效厚度、孔隙度、渗透率、丰度、勘探成熟度、非均值性、勘探成功率、含气组合等8个地质风险指标,以某油田某地区的7个井区为例,结合地质风险评价的特点,运用灰色聚类法对其进行地质风险综合评价研究,使以各个区块为单元的未动用储量的优劣得以量化表现。Geology complexity of proved nonproducing reserves decides its economic evaluation difficulty.Therefore ,when the geology risk meability, abundance, exploration assessment is done,the geology maturity, heterogeneity, exploration risk index as effective thickness, porosity, persuccess ratio and gas combination are selected.Using the gray cluster method,this paper conducts the synthetic evaluation and risk taking 7 well blocks in a certain region as an example and according to geology research on geological risk assessment characteristics,which can quantize and display the quality of nonproducing reserves in each area.
