Abstract
The invention discloses a process for preparing thickening water drive for oilfield exploitation. The process includes the steps of 1, by weight, adding 40-50 parts of sea water, 0.2-0.5 part of polyvinyl alcohol and 0.5-1.0 part of polyethylene oxide to a first mixing pump and then mixing uniformly under the temperature of 60-65 DEG C to obtain a first mixed solution; 2, by weight, adding 40-50 parts of sea water, 0.1-0.3 part of fatty alcohol polyoxyethylene ether sulfate, 0.2-0.8 part of lignosulfonate and water to a second mixing pump and then mixing uniformly under the temperature of 63-70 DEG C to obtain a second mixed solution; 3, adding the first mixed solution from the first mixing pump and the second mixed solution from the second mixing pump into a maturation tank to mature for 3.2 hours, adding bactericide into the matured solution and then filtering the same to obtain the thickening water drive. The process for preparing thickening water drive is simple and the thickening water drive prepared by the process has good oil displacement efficiency.
