Sediment Deformation

Abstract Drilling to the bedrock of ice sheets and glaciers offers unique opportunities for examining the processes occurring in the bed. Basal and subglacial materials contain important paleoclimatic and paleoenvironmental records and provide a unique habitat for life; they offer significant information regarding the sediment deformation beneath glaciers and its effects on the subglacial hydraulic system and geology. The newly developed and tested Antarctic subglacial drilling rig (ASDR) is designed to recover ice and bedrock core samples from depths of up to 1400 m. All of the drilling equipment is installed inside a movable, sledge-mounted, temperature-controlled and wind-protected drilling shelter and workshop. To facilitate helicopter unloading of the research vessel, the shelter and workshop can be disassembled, with individual parts weighing <2–3 tons. The entire ASDR system weighs ~55 tons, including transport packaging. The ASDR is designed to be transported to the chosen site via snow vehicles and would be ready for drilling operations within 2–3 d after arrival. The ASDR was tested during the 2018–2019 summer season near Zhongshan Station, East Antarctica. At the test site, 2-week drilling operations resulted in a borehole that reached bedrock at a depth of 198 m.

Hydraulic disc brake is essential for meeting the requirements of safety and economic efficiency during drilling and work-over procedure. To address this need, we have developed a programmable logic controller controlled novel hydraulic disc brake system with capability to apply control strategy similar to anti-lock braking system for hoisting system of truck-mounted drilling rig. This paper is to investigate the complicated interaction between the work clamp and the hydraulic control system. So designers can use this model to decide which control strategies are more suitable for the disc brake. This is demonstrated by modeling the advanced hydraulic system and simulating influential factors on dynamic characteristics of hoisting system disc brake, with the application of the Advanced Modeling Environment for Simulations of Engineering Systems. The method of modeling and simulation provides a simple, effective approach to studying hydraulic disc brake for hoisting system.

The Core

The hydraulic vibration head is the core component of sonic drilling rig, and the performance of its hydraulic system influences the technology of sonic drilling directly. The structure and hydraulic system of the hydraulic vibration head are designed, and the AMESim model of the hydraulic system is established in the paper. The hydraulic vibration system is simulated and analyzed to find out the influence rule of vibration frequency on the system performance. The results show that the larger the vibration frequency f is, the smaller the amplitude H is, and the displacement response of the vibrating piston approximates the sine curve.The velocity and acceleration of the vibrating piston accordingly increased, and the exciting force F of the vibrating piston increased significantly.

Feeding Systems

Feeding pressures control of hydraulic drilling rig is a critical technology of drilling quality. In order to control feeding pressure accurately during hydraulic drilling rigs working, A new feeding system was proposed, based on the cartridge valve controlled by high speed on/off valve. Feeding pressure was exported proportionally via control of high speed on/off valves input PWM signal. Its model was built by AMESim software, to analyze characteristics of the cartridge valve and research the feeding systems response to pressure-commanded signal. The results show that the feeding pressure can be regulated proportionally and the control performance of the feeding pressure can be improved by increasing moderately PWM signals frequency, which provides a reliable reference for further optimization of hydraulic system of drilling rig.

Drilling rig sticking, which poses great danger for operators in coal mine production, occurs frequently owing to various factors during the process of drilling in underground coal mines. To solve the sticking problem, the hydraulic power of the drilling rig, which has a significant influence on sticking, is studied. The relation between the torque provided by the hydraulic power unit and the torque required is determined. A model of the hydraulic system based on the multi-way valve applied in a typical drilling rig is built using the hydraulic component design of AMESim; then, the hydraulic system model is simulated under similar working condition with actual condition. Subsequently, a theoretical expression is deduced according to hydraulic and mechanical theorems, and a control method based on dynamic performance curves and relation expression (MDPRE) combining system simulation with theoretical expression is proposed. Finally, experiments are conducted 10 times/shifts to validate the MDPRE. The ultimate results show that the solution is viable and effective.
