介绍了海相碳酸盐岩地层的地质特征,分析了海相碳酸盐岩地层随钻测井与测井资料解释存在的难点,并有针对性地探讨了技术对策和国内随钻测井仪器的研发方向。分析表明,国内随钻测井仪器无法满足现有要求,急需研发随钻多探测深度多频电阻率、随钻补偿中子及密度、随钻电波、核磁共振成像等随钻测井仪器。
The geological characteristics of marine carbonate stratum are introduced. The difficulties in interpretation of logging-while-drilling data and logging data of marine carbonate stratum are analyzed, and the technical countermeasures and domestic logging-while-drilling logging Instrument research and development direction. The analysis shows that the LWD instrument can not meet the existing requirements and there is an urgent need to develop LWD tools such as multi-depth resistivity while drilling, neutron and density while drilling, MWD and NMR imaging.
