摘要
测井是水合物深入勘探阶段—钻探阶段的必要手段,已得到较好应用。文章综合介绍和分析了ODP204航次、加拿大西北马更些河三角洲地区Malik 5L-38井、IODP311航次及日本南海海槽等较新的水合物钻探调查的测井方法与技术,重点分析了核磁测井、电磁波测井及偶极横波测井等测井新技术在水合物勘探与评价中的应用,对测井方法在水合物勘探中存在的问题进行了讨论。
Well logging is the indispensable approach when the exploration of gas hydrates steps into drilling and good results has been illustrated. The paper briefly introduces and construes the well logging technologies employed in the exploration of gas hydrates of Mallik 5L-38, IODP311 and MITI Nankai-trough well. The emphasis lies in the analysis of the application of NMR, EPT and DSI logging to exploration and evaluation of gas hydrates. Also some issues during the well log interpretation of gas hydrates are discussed.
