汶川地震断裂带科学钻探项目深孔取心钻探设备的研制与应用

The Research and Application of Deep Hole Core Drilling Equipment for Wenchuan Earthquake Fault Scientific Drilling Project

摘要:

深孔取心钻探设备是为满足汶川地震断裂带科学钻探项目(WFSD)3000 m深部取心钻探需要而自主研制的我国首套科学钻探专用设备，包括KZ3000型全液压钻机以及深部钻探配套用高压泥浆泵和钻杆钻具等。该套设备集全液压、高速顶驱、大口径、深部取心于一身，具有综合能力强、工艺适应性广、操控智能程度高等特点，在WFSD-2孔深部取心钻探中，各项功能满足设计要求，应用情况良好。该套设备作为我国深部钻探装备的阶段性创新成果，在科学钻探、深部找矿和浅层油气钻采中，具有一定的推广价值。

Abstract:

Deep hole core drilling equipment, including KZ3000 drill rig, high-pressure mud pump and wire-line coring rods and tools, is the first scientific drilling system in China, which was independently designed and manufactured to meet the needs of Wenchuan earthquake fault scientific drilling project (WFSD). The equipment is set fully hydraulic, high-speed top drive, large diameter and deep coring in one, featuring good comprehensive capability, wide process adaptability and high intelligence of manipulation. During the WFSD-2 deep hole core drilling, it worked well by meeting the design requirements in all functions. As stage innovations for deep drilling equipment, it has a potential market value in scientific drilling, deep prospecting and shallow oil and gas drilling.
