​JCDRILL Crawler-mounted Core Drilling rig: A Technical Overview

Introduction

Core drilling rig is a kind of core drilling equipment. It is mainly used for the survey and exploration of metal and non-metallic solid minerals. In addition, it can also be used for engineering geological survey, hydrogeological survey, oil and gas field survey and exploration, and water well drilling. Since the core drilling rig requires the removal of relatively complete, non-mixed and non-flexible stratigraphic rock samples, the core drilling rigs are all rotary drilling rigs. According to the structure of the drilling rig slewing device, the core drilling rig can be divided into three categories: vertical shaft type, turntable type and mobile slewing device type.

The Crawler-Mounted Core Drilling Rig Composition

The composition of core drilling tools mainly includes the following parts：

Coring drill bit: used to drill the core and is a key component in the drilling process

Outer core casing pipe: withstand drilling pressure and transmit torque to ensure stability and power transmission during drilling

Inner core pipe: used to store and protect the drilled core to ensure the integrity and protection of the core

Core claw: used to cut, support and remove the core to ensure that the core can be removed smoothly and for subsequent analysis

Core Barrel, reamer shell, stop ring, core lifter, core lifter seat, landing ring, stabilizer, landing shoulder, spearhead piont, latch and other auxiliary components: these components play a role in suspension, diversion, back pressure adjustment and stabilizing during the drilling process to ensure the smooth progress of the drilling.
