摘　　要：大洋钻探诸多科学目标的实现与包括钻探、取芯、测试和海底观测技术在内的各种新技术的开发和革新密不可分。即将开展的IODP计划,将对各种技术提出新的要求。在钻探技术上,将联合使用多平台,以实现区域更广深度更大的钻探作业;在取芯技术上,取样范围更广,从各种岩石取样到地下流体的取样,并要求样品保持原始状态,同时确保获得更高的岩芯采收率;在测试上,要求采用随钻测试技术,以适时地获得地下真实信息;在观测技术上,要求开发各种工具,去除由于钻探造成的扰动,使得各种观测仪器能够进行长期的跟踪观测。Achievements of the scientific ocean drilling are closely related to the developments and renovations of new technologies in drilling ,coring ,measurement and observation. Scientific objectives of IODP require new technologies. The use of multiple drilling platforms will permit operations in wider and deeper water areas. By use of new coring technologies, scientists can obtain a wide range of samples from rocks to fluids, while at the same time maintaining the in situ situation and enhancing core recovery. LWD will be used to acquire real information in subseafloor. Many new measuring tools are being developed to satisfy the demands of downhole measurements. Tools for long term observation are to be developed that are able to obviate drilling perturbations.
