瑞典目前正在试验一种取代常规钻管钻进的、新颖的岩心钻进系统。这种系统以一套安装在柔性软管内的钻具装置在岩层钻进中获取岩心。在钻进时,安放在钻具总成内的电传感器,通过嵌入柔性软管内的电缆不断地输出测井数据。这一命名为“T”钻进系统的新工艺,由于能充分节省升降钻具的时间,从而降低了生产成本。当“T”钻进系统内的岩心管装满以后,只需将钻具提升到地面,取出岩样后再放入井底,即可继续钻进。这样, Sweden is currently experimenting with a novel core drilling system that replaces conventional pipe drilling. This system takes cores in a rock formation with a set of drill devices installed in flexible hoses. While drilling, electrical sensors placed in the assembly of the drill continue to output logging data through cables embedded in flexible hoses. This new name, named “T”, is a new process for drilling systems, which reduces production costs by substantially saving the time needed to raise and lower the tool. When the core tube in the “T” drilling system is full, simply lift the drill to the ground, remove the rock sample and then put it into the bottom of the well to continue drilling. such,
