绳索取芯钻杆材质及其加工质量是绳索取芯钻进的关键因素之一。我队先后加工钻杆1600多米,接头500多付,钻进8360米,经强行扭转、顶、拉的试验,基本上满足了绳索取芯钻进的要求。现将野外队如何搞好绳索取芯钻杆的加工,简介如下。一、选择高强度的优质管材和合理的钻杆螺纹绳索取芯钻杆由钻杆体和公母接头组成。钻杆单根不能超过3米,每根单根配公 Rope coring drill pipe material and the quality of its processing is one of the key elements of rope coring drilling. Our team successively processed more than 1,600 meters of drill pipe, over 500 joints and 83,600 meters of drilling. After forced reverse, top and bottom tests, the team basically fulfilled the requirements of rope coring drilling. Now the field team how to do a good job of rope coring drill pipe processing, as follows. First, the choice of high-strength high-quality pipe and a reasonable thread drill pipe thread core drill rod body and male and female joints. Single rod can not exceed 3 meters, each with a single male
