井下节流防治气井水合物技术研究与应用

Downhole choke technology is to adjust downhole pressure through installing the choke in an appropriate position on the tube.

气井井下节流工艺是将节流器置于油管的适当位置来实现井下节流调压,利用地热对节流后的天然气加热,改变天然气水合物的生成条件,对防止水合物生成起到了积极作用。

Aiming at this productive problem,downhole choke engineering research was developed.

主要针对高压气井冬季易堵、存在较大安全隐患的生产难题,开展井下节流工艺技术研究。

lower nodal point) is rather complex when the tank bears liquid static pressure.

搁置在钢筋混凝土环梁基础上的 150dam3 大型储罐 ,当承受液体静压时 ,罐底板与最底层罐壁板联结处(即下节点 )的应力状态十分复杂。

The experiment shows that the production of gasfield which is installed downhole throttle is not high,but it has stable pressure and good productive effiency.

研究表明,安装了井下节流器的气井尽管早期产量不高,但生产压力相对变化不大,稳产时间长,生产效果较好。

The underground restriction of condensate gas well is a very important link in the exploitation of condensate gas reservoirs.
