Q Series Wireline Core Drilling Tools Product Introduction

BQ NQ HQ PQ Wireline Core Barrel

Q Series Wireline Core Drilling Tools are standard DCDMA-compliant double/triple tube wireline core barrel systems widely used in geological exploration, mineral mining, geotechnical investigation, water well drilling, and tunnel engineering. Covering full specifications of BQ, NQ, HQ, PQ standard wireline core barrels, Q3 series core barrels and matching wireline drill rods, this complete wireline coring system is engineered for deep hole hard rock core drilling, soft and fractured formation core sampling, and high-precision rock core recovery projects.

This professional wireline core drilling tool set consists of full-series core drilling accessories, including inner tube assembly, outer tube assembly, overshot assembly, core lifter, core catcher, stabilizer ring, wear guide ring, retainer ring, reaming shell, diamond core bit, impregnated diamond bit and other core barrel spare parts. All components adopt high-strength heat-treated alloy steel and premium copper alloy materials, featuring strict forging process, high concentricity, excellent compression resistance, mud erosion resistance and abrasion resistance, effectively solving tube friction, tool vibration and hole deviation problems during deep drilling operations.

Different from conventional drilling tools, our Q series wireline core barrel supports non-tripping coring operation, which retrieves rock cores through inner tubes without pulling out the entire drill string. This design greatly improves drilling efficiency, shortens working cycles, and achieves ultra-high core recovery rate for undisturbed core samples. The matched wireline drill rod with standard Q thread ensures stable torque transmission, tight connection and reliable sealing, adapting to medium and deep hole drilling of 100m to 2000m in various complex formations such as hard rock, broken rock and soft soil layers.

Available in multiple configurations including standard double tube core barrel, thin kerf core barrel and triple tube core barrel, our Q series wireline drilling tools feature simple installation, strong compatibility and long service life. All products comply with international DCDMA industry standards and pass rigorous quality testing, widely recognized in gold mine, copper mine, coal mine and underground mineral exploration projects. As factory-direct professional drilling equipment, our wireline coring system delivers cost-effective performance, high penetration rate and stable drilling track, making it the preferred reliable solution for global geological survey and mining exploration core drilling projects.
