The most active new consultant award, one of the three winner awards of the category, was recently granted to Dr XJ Jing (representing an active research team mainly composed by Dr XJ Jing, Prof L Cheng and Dr WO Wong), by the PTeC of PolyU as a recognition for the dedicated efforts made within the past one year for solving important engineering issues and serving industry.
A key advanced technique in modern petroleum technology is the development of Measurement-While-Drilling (MWD) systems to feed back drilling and directional information in real-time, or Logging-While-Drilling (LWD) systems to transmit formation evaluation data. Both MWD and LWD systems can greatly facilitate monitoring and control operations even as drilling is on-going.
The MWD or LWD systems are usually designed in a modular manner, and can be run with various sensor combinations to fit the requirements of the well plan. Drilling process can produces excessive vibration up to 20grm in the frequency range of 5-2kHz and shock up to 500g, and environment temperature could vary from -400C to 1750C. In such a working environment, all electronic units, control panels and sensors must be well installed with sufficient protection striving for a longer life cycle.
The research and development team, led by Dr XJ Jing, strongly supported by the HoD Prof L Cheng and Dr WO Wong, and also composed by some research staff including research students/associates/assistants in the ME department, has actively and dedicatedly conducted a series of R&D and investigated several key engineering issues related to vibration isolation and protection in the MWD/LWD systems mentioned above in the past 4 years, collaborated with and also funded by the China Oilfield Service Ltd (COSL).
Aiming at high-tech R&D and innovative solutions to engineering problems guided by PolyU’s vision as “where innovation meets application”, the team has successfully provided technical consultant services to the COSL, systematically identified several core and generic problems in vibration control and dynamics analysis for further investigation, and cordially created some industry-oriented topics for undergraduates and Msc students for FYP and thesis projects.
The China Oilfield Services Limited (COSL) is a leading comprehensive oilfield services provider in offshore with over 40 years experience. Its core businesses cover each phase of oil and gas exploration, development and production. The COSL is one of the three major components of China National Offshore Oil Corporation ("CNOOC").
