The main component of this series of water blocking agents for oil production is polyquaternary ammonium salt. The main chain of the polymer in the water blocking agent is a linear water-soluble polymer, and the auxiliary chain is composed of polyethylene derivatives, which can react with the polymer of the main chain to form a highly bifurcated water-soluble copolymer . Water blocking agent is liquid at normal temperature and has a certain viscosity. During the construction process, the water shutoff agent can change the electronegativity of the fine sand particles to the electroneutrality, gather under the action of the representative van der Waals force, reduce the channel gap between the quartz sand, so as to achieve the purpose of water shutoff. This series of water plugging agents are mainly suitable for water plugging and water control in horizontal wells.
Storage and transportation conditions
1. The water blocking agent need to keep the container tightly sealed when storing.
2. The water blocking agent should be stored in a cool and ventilated place, and should be kept away from heat and fire sources.
3.The water blocking agent should be protected from impact during transportation. It is strictly forbidden to mix with food for transportation.
