[本刊讯]不久前,中国地质调查局北京探矿工程研究所在中国南海恩平区块100m水深海域,成功进行了TKP-1保压取心钻具的海底钻探取心试验。原位保压取心钻探技术一直是国内外专家研究的技术难点,目前主要掌握在西方国家手中。地调局北京探工所技术人员经过一年左右的技术攻关,研制出TKP-1保压取心钻具。该保压取心钻具通过创新式设计,利用压力补偿系统不断向取心筒补充压力直至与地层压力平衡,机构简单可靠,操作方便,得到了有关专家的肯定。本次试验共进行了6
Not long ago, the China Geological Survey Beijing Institute of Prospecting Engineering successfully carried out the bottom drilling coring test of TKP-1 core-pressure coring tools in a 100-meter deep sea area of Enping block in South China Sea. In-situ packing pressure coring drilling technology has always been a technical challenge for domestic and foreign experts to study, mainly in the hands of western countries. To adjust the Bureau of Beijing exploration workers by the technical staff after about one year of technical research, developed TKP-1 packing core coring tools. Through the innovative design, the bored coring drill utilizes the pressure compensation system to continually replenish the coring cylinder until it is balanced with the formation pressure, the mechanism is simple and reliable, and the operation is convenient, which is affirmed by relevant experts. This experiment has been carried out 6
