Abstract

Zhu jiadun gas poo l is an edge w ater gas poo.l The
buried depth is over 3700 m eters. The tem perature o f gas
reservo ir is higher than 100􀀁 . The gas w ells have a h ighoutput. As the gas output is dec ided by the gas se lling
m arket, the output always fluctuate and the gas we lls
genera lly produce w ater. Based on the abovem entioned
characters o f gas poo l and the m in im um flow rate theory, the
techniques, wh ich is the gas recovery by w ater dra inage w ith
optim ized tube and the gas recovery by foam w ater drainage,
have been stud ied. It is know n that gas recove ry by foam
w ater dra inage w ith 40. 3mm tube or Ych fo am ag ent could
effectively dra in the residua l flu id a t the w e ll bottom.
Consider ing the econom ic benefit, the first cho ice is the
technique of gas recovery by foam wa ter dra inage.
