摘要
从断层封闭的本质出发，分析了影响断层封闭性的地质因素和评价封闭性的主观因素。建立了相应的地质模型和数学模型，通过给定树状模型各叶点的定量数值，计算断层封闭性的综合因数，对断层封闭性进行了半定量的评价研究。并把上述研究方法具体应用到松辽盆地他拉哈断裂带，对该地区４条主要断裂进行了封闭性评价，依据评价指标确定他拉哈与十五里岗子断裂封闭性差，太和东和太和两断裂封闭性较好。这一结论与勘探实际基本相符。
To analyse geological factors and subjective factors of fault seal which have effecfs on fault seal property. To set up evaluating network system and geological model as well as mathematical model. This method of fault seal study was applied to area of Talahei in Songliao basin and the seal property of four faults in area of Talahei was tested. The seal property of faults on Talahei and East Talahei is good. The conclusion tallies with field prospecting.
