| titleOfInvention | a control agent |
| abstract | The invention provides a control agent, which relates to the technical field of oil-water well powder fine sand sand control. In the control agent, the control agent is composed of agent A and agent B; the agent A is composed of low molecular weight quaternary ammonium salt cationic polymer and alcohol; the agent B is composed of anionic polyacrylic acid amine polymer and binary polymer , the binary polymer is polymerized from a mixture of acrylic acid and acrylamide monomers, a crosslinking agent and an initiator. The invention has the functions of sand control and particle migration prevention, and the control agent is mainly used in sand producing wells, especially silty fine sand oil and gas wells, which can meet the sand control requirements of oil and gas layers, greatly increase the production validity period and slow down the speed and speed of ground reduction. Increase oil production. |
