摘要
本文论及龙门山前陆盆地深层海相碳酸盐储层地震预测的岩石物理学基础与有效的预测方法技术问题。龙门山前陆盆地深层震旦系至中三叠统海相沉积以碳酸盐岩为主,厚4000～7000m,天然气资源蕴藏量巨大而探明率低,油气勘探的关键在于寻找优质储层。基于对地震资料和井资料的分析,认为该区段的储层主要是生物礁滩相白云岩和发育构造裂缝的碳酸盐岩。依据井资料,总结介绍了该区三叠系马鞍塘组、雷口坡组和嘉陵江组地层与碳酸盐岩储层的地震波速度、密度、电阻率等物性参数特征。在分析介绍储层地震预测原理方法与碳酸盐岩储层地震预测问题的基础上,介绍了作者研究提出的地震纹分析方法的概念、原理及其在含气储层检测中确定的应用效果。
This paper presents the petrology and petrophysics characteristics of the marine strata and the seismic prediction techniques of carbonate reservoir in the deep of Longmenshan foreland basin.The thickness of the marine strata,from Sinian to Middle Triassic,is about 4000m to 7000m.The marine strata,mainly carbonate,are rich in natural gas,but the proved rate of the gas is very low.The key problem of the gas exploration in the region is to find high quality reservoir.Based on the analysis of the well data,seismic data and geological data,it has been concluded that the carbonate reservoir types are mainly shoal-reef dolomite and fractured carbonate.Based on well data,the paper presents the petrological characteristics of the Triassic Ma'antang,Leikoupo and Jialingjiang formations,and shows the rock's petrophysical parameters such as seismic velocity,density,resistivity,and so on.This paper discusses the effective techniques for the seismic prediction of the carbonate reservoirs in the region,and presents a novel reservoir seismic prediction technique named seismic-print analysis.
