| description | How to exploit efficiently unconventional hydrocarbon has become an important step to solve the problem of increasing reserve and production of oil & gas in China. Aiming at unconventional oil & gas well engineering problems such as large cluster well design, single trip drilling operation, downhole radiofrequency heating, efficient exploitation of coalbed methane, and so on, this article analyzes the related research progress briefly at home and abroad, and focuses on the research results of the author's team. Technical contents introduced in this article mainly include: the design methods of large cluster horizontal wells with considerations of directional drilling operation limit and the anti-collision while drilling; research advances in crucial techniques for the single trip drilling operation related to the innovative research work on efficient PDC bits, steering bottom-hole assembly, drilling parameter optimization, new type of drilling fluid and so on; general situation of development and the research results in downhole radiofrequency heating technology for unconventional oil recovery by the in-situ conversion process; finally, briefly introducing significance and technical challenge of the coalbed methane development and utilization, and focusing on the representative achievement of coaled methane exploitation in China, which is related to key techniques involving the geological evaluation, magnetic steering drilling, well completion & washing, efficient fracturing with combination of the preposed nitrogen and activated water and so on. A review of the research advances may be a beneficial reference in optimal design and operation control of well engineering technology for unconventional hydrocarbon. |
