摘要
当前水文水井钻探施工过程中,工艺相对落后且集成化程度低,新技术、新方法、新工艺引进和创新不足。在水文水井钻探中,从井底返回地面的泥浆中含有大量的岩屑和砂粒,仍主要采用人工捞砂、泥浆池和沉淀池自然沉降的作业方式,效率较低。为实现钻探施工中设备的自动化、模块化,提高施工效率,针对青海省复杂的地质与气候环境,研制了一种绿色勘查水文地质钻探自动化泥浆循环净化装置控制系统,包括远端控制子系统、近端控制子系统和泥浆加热循环子系统。为提高控制系统的抗干扰性,选用以PLC为控制核心的系统硬件,对泥浆净化装置控制系统硬件和控制系统软件等进行了设计,且系统采用模块化和可靠性设计方式,在实际应用中具备方便运输、可靠性高、适应性好等特点。
In the current drilling process of hydrological wells,there are relatively low level processing and integration.And the introduction and innovation of new technologies,methods and processes are not sufficient.In the drilling of hydrologic well,the mud returned to the ground from the bottom of the well contains a large amount of rock cuttings and sand particles,which are mainly treated by the natural settlement by artificial sand bailer at mud pit and sedimentation tank,with lower efficiency.In order to realize the automation and modularization of drilling equipment and improve the construction efficiency,an automatic mud circulation purification device control system with green exploration and hydrogeological drilling was developed according to the complicated geological and climatic environment of Qinghai Province,including remote control subsystem,near-end control subsystem and mud heating cycle subsystem.In order to improve the anti-interference performance of the control system and increase its reliability,the hardware of the system selects PLC as the control core.The hardware and software for the mud purification device are designed with modularization and reliability in the control system.In practical application,this system has the characteristics of convenient transportation,high reliability and good adaptability.
