Application of All Hydraulic Truck-mounted Drilling Rig in Cluster DTH Inverse Well Construction

Publish Date: 10 June 2014

Abstract

Abstract

Almost all the drilling contractors accomplish inverse well construction with mechanical raise boring machine, but it usually works inefficiently.Engineers in CNIET have developed a fast and safe process to drill inverse wells by adopting SDC1500 all hydraulic truck-mounted rig matched with new cluster inverse well pneumatic DTH to solve the inefficiency. This construction process is summed up with the case of large diameter drainage well in a coal mine of Inner Mongolia.
