Application of local area network system of wireless sensor with low-voltage and micropower based on wireless routing protocol transmission in drilling field.
The wireless sensor local area network system consisting of micropower wireless transceiver module can he applied to the drilling field, the system data is reliable with stronger re- al-time, in order to promote in the field, its principles are briefly described. By the wireless routing protocol developing and making designs of our own, with the aid of a self-de- signed wireless sensor with low-voltage and micropower, the efficient wireless signal transmission was completed and data sharing with the optimal path for free transmission was a- chieved between acquisition nodes of wireless local area net- work, and measurements of the wireless sensor can be sent to each application software, such as wireless alarm system software for monitoring drilling fluid, forming an application package system of wireless local area network in drilling field. The paper introduced the design and function of the wireless local area network system with low voltage and micropower that was made up by the wireless routing protocol in field monitoring the parameters of drilling fluid level. 相似文献

Application and research of the logging technology for LWD X-ray diffraction analysis. Zhan Rong, Zou Xiaochun and Li Fang. Mud Logging Engineer- ing, 2012, 23（4）： 1-5 With the oil and gas exploration deepening, the exploration objects are transferring to the more complex geological condition blocks, coupled with PDC bits, more fine-tooth tricone bit, foam drill- ing, air drilling, the application of the above new techniques make the lithology identification more difficult, traditional methods which relied on the naked eyes and magnifier to identify lithology can not meet the requirements of LWD lithology identi- fication and real-time establishing geological lithol- ogy sections.

Practice and developing trend of mud logging engineering in deep water of China. Dai Yiding, Sun Jinshan, Li Jianzhou and Du Kezheng. Mud Logging Engineering, 2014, 25 （ 4 ） ： 1-5
With oil and gas exploration moving to deep water, deep water mud logging is charged with two tasks of oil and gas discovery and engineering monitoring. There is temperature difference in water depth of deep water wells, the performances of risers and booster pumps determine the main factors in deep water mud logging. 相似文献

CONSTRUCTION AND APPLICATION OF DELAYED COK- ING EXPERIMENTAL UNIT WITH ONLINE RECYCLE OIL
Huang Xinlong , Wang Hongbin , Ya Fei , Li J ie （ SINOPEC Luoyang Petrochemical Engineering Corporation, Luoyang, Henan, 471003） Abstract：As the feedstock to delayed eoker becomes heavier, in order to maintain the long-term and safe operation of the coker, it is important to use a delayed coking experimental unit to find out the impact of operating conditions and the addition of additives on coking process so as to guide the practical design and production. LPEC has developed the delayed coking experimental unit with online recycle oil after years of research. This experimental unit is under the control of DCS, the process parameters such as temperature, pressure, flow rate and recycle ratio, which is within the range of 0-1.5, are in stable status. The start-up and shut-down are simple and safe, the operation is easy, the furnace tube is not easy to coke, the decoking of coke drum is convenient, the experimental efficiency can be improved by more than 10 times, and the material balance is above 99. 3%. This technology takes the lead at home and reaches the international advanced level. Key words： Coking; Experimental unit; Recycle ratio; Recycle oil; Heating furnace; Decoking 相似文献
