Abstract
In order to widely popularize coiled tubing operation technique in China oil and gas field, with the help of coiled tubing new technology popularization platform of CNPC, qinghai oilfield took full advantages of coiled tubing operation equipments, carried out 27 test applications of technical field including drilling, well completion, oil recovery and workover, gave full play to superiority of coiled tubing operation such as short operation cycle, low accident rate, less formation damage and good reenterability, and gained significant economic benefits. Based on application, experiences of coiled tubing operation technique in qinghai oilfield were summarized, including insisting on corporate culture guiding concept transformation, sustainable innovation based on oil and gas field demands, promoting scale application and changing development mode with the help of special platform; a high level of specialized technical services team was established, coiled tubing nitrogen foam erosion washing operation of low pressure gas well, coiled tubing wiper trip and well washing integration operation, coiled tubing water injection well descaling and some other technologies were formed, and the transformation of plateau downhole operation from low end labour service to modern downhole operation technological mode was realized. Finally, the application of coiled tubing technology in qinghai oil fields was expected, and the application of bringing into production, maintenance, overhaul and acid fracturing were expanded.关键词
