| 摘 要： | 在气测背景值的干扰下,所测气测值不能客观反应地层含油气情况,应该加以剔除。利用数学方法,在测点上部一定深度范围内,在考虑权重的情况下,采取气测最小值与随机值相叠加的方法来判断气测背景值的大小,减少了气测录井背景值的影响,能有效地排除假异常,有助于发现和评价油气水层。

| Abstract: | Because of background values of gas logging,the obtained gas logging values cannot reflect true hydrocarbon-bearing condition of formation;therefore,the value should be eliminated.With mathematical methods,applying the sums of minimal gas logging value and random gas logging values to judge background value while considering weight above certain depth,the effect of background values was lowered and then false anomaly was effectively eliminated, which helps to discover and evaluate hydrocarbon reservoir. |
