为解决常规海底岩心钻机在深海CRC调查中效率低、成本高、样品代表性差等问题，我国研制了一种新型的“海底浅孔多芯岩心钻机”，该钻机一次可获得3个岩心。本文介绍了该钻机的基本设计、技术指标和工作原理，并详细介绍了其主要组成部分，如专门设计的多芯取心机构、蓄电池驱动的液压系统、水下和水面控制系统等。文中还给出了该钻具在室内和太平洋海域多次取心试验的结果及其分析。
In order to solve the problems of low efficiency, high cost and bad representativeness of sample in using conventional seafloor rock core drills to carry out deep sea CRC investigations, A new type of “Seafloor Shallow-hole Multi-coring Drill” was developed in China, which is able to obtain up to 3 rock cores on one deployment. This paper describes the basic design, specifications and operation principles of the drill, and introduces in detail some of its important components such as the specially designed multi-coring mechanism, the battery powered hydraulic system and the underwater and surface control system. The results and their analyses of the drill’s multi-coring tests in lab and in Pacific Ocean are also given in the paper.
