摘要
井下节流技术是实现大庆油田公司预计新开深层低产气区块经济有效开发的重要技术手段。重点讲述了在徐深气田试验井下节流技术来达到降低地面压力、防治天然气水合物的目的。通过试验前后的生产情况对比显现了井下节流技术的优势,同时针对试验过程中存在的实际问题进行了详细地分析。通过在该区块进行的节流技术试验,加深了对该技术的认识,取得了一定的效果,为以后大面积推广该技术积累了经验,奠定了基础。
Downhole throttling is the key means to develop the anticipative gas well.Descript the tests in Daqing Xushen gas field which aim to degrade the surface pressure,and the hydrate is prevented as well.Through the production before and after the test,the advantage of downhole throttling technology can be seen,meanwhile the problems in application are analyzed in detail,Field applications of the technique in 4 wells achieves satisfactory results,and experiences provide the feasibility of application on a large scale.
