根据吞吐井自喷周期短、井下温度高、出油管线回压高以及井浅等特点和常规转抽方法存在的问题,阐明了开展不动注汽管柱转抽油工艺技术研究的重要性。此外,还较详细地介绍了新研制成的吞吐井停喷后,不需修井能直接转抽的不动注汽管柱转抽工艺,并根据这套工艺的性能和现场应用情况,阐明了所节约的直接费用和该工艺总的经济效益。 According to the problems such as the short period of the injection well, the high temperature in the downhole, the high back pressure of the oil pipeline and the shallow wells, the importance of researching on the technology of transferring oil from the fixed pipe to the well . In addition, a more detailed description of the newly developed huff and puff stop after injection, without workover can be directly transferred to the fixed injection pipe steam extraction process, and according to the process performance and field application, clarify The direct costs saved and the overall economic benefits of the process.
