【摘要】 在四川盆地的石油勘探中发现其深部三叠系海相地层含有富钾卤水,钾品位异常高;这些卤水本身就是潜在的钾盐资源,具有良好前景。文章把卤水储层作为一种特殊的含流体沉积储层,利用石油勘探中的成熟技术——地震勘探,比如地震资料储层预测及流体识别技术等,对四川盆地的三叠纪盐盆典型储卤构造进行地球物理综合解释与储层预测工作,初步掌握了四川盆地的富钾卤水储层的地震波场响应特征,建立了主要利用地震资料进行富钾卤水储层预测的预测模式,并在实际应用中取得了较好的效果。更多还原

【Abstract】 In recent years,potassium-reach brine was discovered in Triassic marine strata with extra high percentage of KCL during petroleum exploration in Sichuan Basin.The brine is a potential potassium resources and the main prospecting target with good potentiality.Based on the thoughts of integrated exploration of petroleum and potassium resources,we take the brine reservoir as a special fluid-bearing sedimentary reservoir and use the mature technologies of petroleum exploration,e.g.seismic reservoir characterization and fluid identification approaches,to interpret comprehensively the geophysical data and predict typical brine-bearing reservoir in Sichuan basin.The seismic response features of potassium-rich brine reservoirs have been primarily understood and the seismic data-based prediction model built.And the approaches have been applied to the practice with good results.更多还原
