起泡剂在井筒积液中的扩散规律研究

RESEARCH ON THE FROTHER DIFFUSION RULE IN WELLBORE LIQUID

泡沫排水采气是一项成本低、见效快、施工容易的排水采气工艺技术,日益受到国内外的普遍关注。文中通过理论研究,建立了起泡剂在井筒积液中扩散的数学模型,弄清了起泡剂在井筒积液中的分布规律。因而减少了施工中的盲目性,提高了作业效率,并将研究结果成功地用于长庆气田4口气井的现场施工。由于该理论模型的建立具有一般性,所以对国内外其它气田的泡沫排水采气也具有指导意义。

Foam drainage gas recovery is a drainage gas recovery technical which is low cost, got effects, use easily, and widespread concerned increasingly by the domestic and the international. On the base of theoretical research, this paper sets up the mathematical model to the frother diffusion in the wellbore liquid loading The distribution rult of the frother in the wellbore liquid loading is known clearly Thus, the blindness under construction is reduced, while the operal ing efficiency is improved. Meanwhile, the results of this pa per are used successfully for the Changqing gas field construe tion of four gas wells. As this theoretical model is set up by the general method, it also has the pilot meaning to other gas wells in foam drainage gas recovery both the domestic and the international
