Oil displacing agent
Appearance：Yellow brown paste or liquid
Valid content≥%：41.5
Water ≤%：58.5
Ionicity：Compound ion type
PH value (1% water solution)：6.5-7.5
oil water interfacial tension mN/m：≤9*10-4~-5
Features:
1. This product is not adsorbed in the carbonate layer;
2. Strong high and low temperature oil carrying capacity;
3. Strong interfacial tension reduction ability;
4. Good compatibility with crude oil;
5. Strong wetting reversal ability, electrolyte resistance and high temperature resistance;
6. The recovery factor is about 30% higher than the usual oil displacing agent.
Uses: The oil used for carbonate rock geological reservoirs is driven by oil displacement aids.
Instructions for use:
1. The high-concentration product is diluted with hot water at 70-80 ° C into a conventional product of 20% concentration, and after cooling, it is a yellow-brown semi-flowing liquid.
2. After dilution, the amount of refilled water is 0.3-0.5%. Under the condition of 65-80 °C, the ideal oil recovery effect can be obtained.
3. Please simulate the actual temperature, water pressure, water quality, rock characteristics, etc. of the formation to determine the optimum dosage to maximize the oil recovery rate.
4. This product has a certain ability of bacteria inhibition, and can maintain the stability of the flooding water without adding or adding antibacterial agents.
5. Use this product as the oil displacing agent, and you can obtain the ideal oil recovery rate without the cooperation of other chemicals.
