针对1991年高分辨率勘探所得雷－1地震剖面反射波连续性差、能量弱的特点，为了用地震勘探方法解决四川盆地油气储层薄、孔隙度低、油气产出能力与裂缝发育程度关系这3个地质问题，1997年在四川盆地罗渡溪构造开展了以查明雷－1构造形态、断层展布为地质目标的高分辨率地震勘探方法试验，得到了一套关于高分辨率地震勘探采集装备配置及野外施工的方法。

Therefore,when the geology risk assessment is done,the geology risk index as effective thickness,porosity,permeability,abundance,exploration maturity,heterogeneity,exploration success ratio and gas combination are selected.Using the gray cluster method,this paper conducts the synthetic evaluation and research on geological risk taking 7 well blocks in a certain region as an example and according to geology risk assessment characteristics,which can quantize and display the quality of nonproducing reserves in each area.

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。
