现在,全苏钻井技术科学研究所和它的彼尔姆分所设计的一系列螺杆钻具中,要算1-195型钻具的使用比率最大。该型钻具已取代了曾在七十年代广泛使用的2-172M型螺杆钻具。
Now, among the series of screwdrivers designed by the Institute of Well Logging Technology and its Perm branch, the 1-195 is the most used. This type of drill has replaced the 2-172M screw drill, which was widely used in the seventies.
