摘要:

为减少常规方法预测生物礁滩的多解性,以地震沉积学理论为主体思路,在分析建南—龙驹坝地区生物礁滩岩相模式与地球物理响应特征的基础上,将地震相控非线性随机反演引入地震沉积学,利用反演结果,并结合地震解释成果进行地震沉积学解释。依据生物礁滩的岩相模式,利用典型井生物礁滩的地震相与反演剖面特征建立生物礁滩识别模式,进行生物礁滩全区追踪预测。钻井资料证实,预测结果较可靠。

关键词: 地震沉积学, 生物礁滩, 岩相模式, 相控反演, 识别模式

Abstract:

To reduce the ambiguity in predicting organic reefs and banks by applying conventional methods, the present paper, guided by seismic sedimentology theory and based on analyses of lithofacies model and geophysical response characteristics of organic reefs and banks in the Jiannan-Longjuba region, made sedimentological interpretations of seismic inversion data by introducing the facies-controlled nonlinear seismic random inversion into the seismic sedimentology theory. According to lithofacies models of organic reefs and banks, a recognition model of organic reefs and banks was established by applying various data of seismic facies and inversion profiles obtained from some typical wells so as to trace back and predict organic reefs and banks over the whole study area. Drilling data indicated that the prediction was highly reliable.
