针对潮汐、波浪、洋流、钻井工程等多方面对录井和随钻测井深度系统、岩屑迟到深度的影响问题，运用装备相关专业传感器、投实物指示剂等方法，利用控制钻井参数、钻进过程中校深等手段，达到在深水恶劣环境下取全、取准各项地质资料的目的，对深水勘探作业保证地质相关资料的准确性具有指导意义，目前在南海东部海域多口深水探井作业都取得良好效果。

Aiming at the influence of tide, wave, ocean current and drilling engineering on logging and logging while drilling depth system and cuttings lag depth, the methods of equipment-related professional sensors, physical indicators, controlling drilling parameters and proofreading in drilling process are used to achieve the purpose of collecting all kinds of geological data in the harsh deep water environment. It is of guiding significance to ensure the accuracy of geological related data in deep-water exploration operation. At present, many deep-water exploration wells in the eastern South China Sea have achieved good results.
