The Application and Developing Trend of the Intellipipe Used in Petroleum Exploration and Production

This paper points out the problems of mud pulse-MWD and electric supply powered by batteries or turbine under downhole, The techniques of advanced drilling, completion and production require both transmit enough electric power from surface to downhole in order to electrically control the downhole instruments, sensors and some hard-wares as well as establish realtime two-directional closed-loop drilling, while has 104-106bps high-speed transmitting ability to transmit 40~50 parameters and multiplexing data flow on the "highway". The paper reviews the development of oil well intellipipes, describes the function and advantages of the intellipipes used in petroleum explorations and productions, this paper briefly introduces the current researching situation and technical programs, designs the methods of how to insert the electrical wires and isolated layers inside the drillpipe, primarily considers some downhole hard-wares fitting with the intellipipes. The paper also has given the diagram of the intelligent drillstring data flow system, emphasizes that the intellipipe is the key technique and innovating engineering for smart drilling, completion and production.
