在油气开采中,水合物的出现会给开采工作带来困难。井下节流技术的运用可以降温减压,有效阻止水合物的生成,从而起到保护地层和提高油气开采率的作用。本文阐述了井下节流技术的工艺原理以及适用条件,并对其起到的效果进行了分析,以期为研究井下节流技术者提供参考。
In oil and gas exploration, the presence of hydrates can cause difficulties in the mining work. The application of downhole throttling technology can reduce the temperature and decompress, effectively prevent the formation of hydrates, and thus play a role in protecting the formation and improving the rate of oil and gas exploration. This paper elaborates the technological principle and applicable conditions of downhole throttling technology and analyzes its effect so as to provide reference for the research of downhole throttling technicians.
