【摘要】 本文首先通过总结四川盆地钾盐(杂卤石、富钾卤水)的测井响应特征,提出钾盐的测井组合识别法;其次为满足大数据量预测处理需求,介绍了钾盐的测井旋回地层学预测法,该方法具有处理速度快,预测准确度高的特点;最后在实际资料处理与解释中,本文采用了测井旋回地层学法初步预测潜在含钾层段,测井组合识别法再对存疑含钾层段精细排查的技术组合策略,对四川盆地三叠系钾盐资源分布进行了预测,并根据预测结果,划分了4期咸化旋回,指明了3个成钾期,圈定了4个成钾有利区。更多还原

【Abstract】 In this paper,we summarized well-logging response characteristics of Sichuan Triassic potash deposits(i.e.polyhalite and potassium-rich brine).And based on that,we firstly put forward well-logging identification method of potash;and secondly we introduced well-logging cyclostratigraphy prediction method of that,which mainly used to effectively speed up data process;and finally,we used the two methods together to depict distribution of Sichuan Triassic potash deposits.Based on our prediction results,we not only dividied six salting forming periods into four salinity cycles,but pointed out three potash forming periods and four favorable potassium areas.更多还原
