| titleOfInvention | Plugging agent for postponing colloid foam and method thereof for oilfield high-water-content aquifer profile modification water plugging |
| abstract | The invention relates to a plugging agent for postponing colloid foam and a method thereof for oilfield high-water-content aquifer profile modification water plugging. The plugging agent is composed of a foaming agent system solution and gas, wherein the foaming agent system solution is formed by uniformly dispersing 0.05-0.30% of foaming agent, 0.4-0.6% of water-drum aqueous emulsion polymer and 0.2-0.4% of multiplex emulsion crosslinking agent; and the volume ratio of the foaming agent system solution to the gas under reservoir pressure is 1:(1-3). The plugging agent for postponing colloid foam is used for oilfield high-water-content aquifer profile modification water plugging, and can enhance the oil recovery rate. The invention also provides a method for oilfield high-water-content aquifer profile modification water plugging. The plugging agent has the advantages of high dissolution rate, easy preparation, low initial viscosity and the like, can satisfy on-line injection, enhances the site operability, and saves the construction time and input cost. |
