摘要: 目前海上多元热流体热采使用的简易式注入管柱存在管柱整体隔热性较差和水平段多元热流体注入不均等问题。为此,研制了隔热关键工具和分段注热工具,并对注入水平段进行了分段设计,形成了海上多元热流体高效注入管柱。该管柱的隔热段主要由隔热油管、隔热接箍、隔热扶正器、隔热补偿器和隔热封隔器组成,具有良好的整体隔热性能,能减少注入热流体的热损失;水平段主要由均衡注入阀、分段封隔器和油管扶正器组成,能够实现水平段均匀注入。隔热关键工具和分段注热工具均能满足在330 ℃高温下长期工作的需求,隔热性能均达到D级,其中均衡注入阀已应用7井次,水平段均实现了均匀注入。研究表明,多元热流体高效注入管柱及其关键工具能够满足海上多元热流体热高效注入的要求。Abstract: At present, the simple heat injection string pipes used by multiple thermal fluids technology in offshore wells have poor whole-pipe thermal insulation, and are uneven in multiple thermal fluid injection of horizontal sections. In order to solve these problems, high-efficiency injection strings for offshore multiple thermal fluids were designed by developing key thermal insulation tools and step heat injection tools and by designing horizontal sections for heat injection by sections. The thermal insulation section of the string consists of insulated tubing, insulated coupling, insulated centralizer, insulated compensator and insulated packer. Due to its excellent insulation performance on the whole, the heat loss of injected thermal fluids dropped. Its horizontal section, which could implement even heat injection in horizontal sections, consisted of uniform fill-up valves, segmenting packers and tubing centralizers. All key insulated tools and step heat injection tools could meet the requirements for long-term operation at 330 degrees and with Grade D in heat insulation performance. The uniform heat allocation device had been applied 7 times to wells with implementation of uniform heat injection in horizontal sections. In summary, multiple thermal fluids could be injected efficiently offshore by using the high-efficiency multiple thermal fluid injection strings together with the corresponding key tools.
