Abstract
Unmanned platforms and light platforms without well workover are usually used in offshore marginal oil field due to the extremely difficulties during developing these oilfield. How to prolong pump inspection cycle and reduce frequency of workover jobs have become one tough question which needs to be addressed immediately. To solve this problem, this paper improved the design of pipe string structure of dual ESP and dual Y shape joint, and developed a completion technique with single Y-joint, dual ESP, flow deflector and multi-sensor string and the coordinated non-API tools which realize the multifunction of production casing. This technique has been first applied in offshore oil field in China, and reduced the wire line operations, solved the problem of ESP motor heat radiation in some isolated low productivity wells. From the first producing in 2009 up to now, the ESP works well even though the production of Well A3H1 reduced to 13.58 m3/d. From the actual results, we have found that this technique effectually prolonged ESP serve life and is suitable for marginal oil field developing.关键词
