天燃气体在开采过程中易产生水合物和井筒积液,容易堵塞开采气管线路,从而影响气体的正常生产,并引发安全隐患。在气体开采中,井下节流技术不仅可以防止水合物产生,提高气体携液量,还能减缓井底压动。本文结合井下节流技术的工作原理及工艺,详细分析了气田井下节流技术的试验。 Natural gas in the mining process easy to produce hydrate and wellbore fluid, easy to block the production of tracheal lines, thus affecting the normal gas production and lead to safety problems. In gas exploitation, downhole throttling technology can not only prevent hydrate generation, increase gas carrying capacity, but also reduce downhole pressure. Combined with the working principle and technology of downhole throttling technology, this paper analyzes in detail the experiment of downhole throttling technology in gas field.
