摘要
吸收系数是油气储层预测的重要参数,它对岩性变化比较灵敏。本文利用信息比法对吸收系数进行求取,然后用吸收系数变化预测地层裂缝发育程度,和其它地震、测井和地质信息相结合直接用于圈定油气分布范围,估算储量分析,对裂缝油气藏进行预测。该方法在实际资料应用中,得了较好的效果。
Abstract. Absorption coefficient is an important parameter in hydrocarbon prediction. It is very sensi- tive to the variation of lithology, basing this characteristic, This paper calculates the absorption coefficient through the rate of information, uses it to predict the fracture degree of lithology via its variety, to delin- eate hydrocarbon distribution and estimate reserves when combines with other seismic data, log, and geo- logic data~ accordingly to predict fractured reservoir. The applicability receipts good effect in actual data.
