Abstract:

In this study the nanoparticles of suitable size and hydrophobic degree were introduced in the liquid as solid foam stabilizer to solve the problem of unloading of deep gas well with high gas temperature (110-150℃) and salinity.The nanoparticles can adsorb onto the gas/water interface to form a solid film which will prevent the coalescence and coarsening of bubbles,therefore the foaming ability and foam stabilizing ability of liquid foam unloading agent were greatly improved.In order to provide guidance for use in gas well,the foaming properties of different concentration of nanoparticles stabilized foam unloading agent was tested in real-time using high temperature and high pressure foam evaluation instrument.Meanwhile,the external factors such as salinity,temperature and pressure on the properties of nanoparticles stabilized foaming agent were also examined.The results show that its initial bubble volume V0 and half-life t1/2 reached as large as 2 160mL and 765s respectively under 250 000mg/L salinity.Besides,its initial bubble volume V0 and half-life t1/2 reached as high as 1 925mL and 700s at 150℃.These data proved that the nanoparticles have strong ability to stabilize the foams.The field application results show that the nanoparticles foam unloading agent performs well.
