Product application: Prepare a solution prior to use and dose it into the crude oil according to the specified ratio. When the crude oil has a high pour point, the dosage may be increased accordingly. For steam‑huff‑and‑puff pretreatment in heavy‑oil reservoirs, the formulation can be prepared by mixing hot water from the central processing station at a 1:100 ratio. During application, the wellbore temperature should generally not fall below 60°C. Inject the prepared solution into the well through the annulus; the pump action ensures thorough mixing of the agent with the heavy oil, achieving viscosity reduction and enhanced production. The specific application, formulation ratio, and concentration may be adjusted based on the actual water content of the well.
1. Product Application:
When used, prepare a solution and dose it into the crude oil according to the specified ratio. If the crude oil has a high pour point, the dosage may be increased accordingly. For steam‑huff‑and‑puff pretreatment in heavy‑oil reservoirs, the formulation can be prepared by mixing hot water from the central processing station at a ratio of 1:100. During application, the wellbore temperature should generally not fall below 60°C. Inject the prepared solution into the well through the annulus; the pump action ensures thorough mixing of the agent with the heavy oil, achieving viscosity reduction and enhanced production. The specific application, formulation ratio, and concentration may be adjusted based on the actual water cut of the well.
2. Performance Characteristics:
1. The low-temperature heavy oil emulsifier is a high-efficiency viscosity reducer specifically designed for certain low-temperature reservoirs. It consists of multiple novel surfactants and additives, exhibiting excellent emulsification at low temperatures (15°C), strong salt tolerance, and superior penetration.
2. Its mechanism of action stems from the surfactant’s low surface tension, low oil–water interfacial tension, and strong water-wetting properties, enabling rapid breakdown and emulsification of crude oil into a very low-viscosity O/W emulsion upon mixing with an aqueous surfactant solution.
3. It requires a low dosage, delivers high viscosity reduction, exhibits excellent emulsion stability, and facilitates easy demulsification. With its outstanding viscosity‑reduction efficiency—achieving a viscosity reduction of over 90% at 15°C—it is well suited for the emulsification‑based viscosity reduction of heavy oil during production and transportation.
