OBSin oil extractiontypical application:

1: Performance and use

OBSIt is synthesized from hexafluoropropylene trimer. It has high bond energy, strong stability, good acid resistance, alkali resistance, salt resistance, oxidation resistance and other properties. It can withstand long-term high temperature without deactivating the surface activity. It can be used as a high-temperature drainage aid, in fracturing fluids that require ammonium persulfate to break gel, and in all systems that need to reduce surface tension.

OBSIt is used in secondary and tertiary oil recovery in oil production. It is a main raw material for the production of oil recovery and drainage aids. It can reduce the surface tension of fracturing fluid or oil-water interfacial tension, and has the advantages of wax dissolution, viscosity reduction, and efficient foaming to aid drainage. .OBSBecause it has higher surface activity, it can significantly reduce the oil-water interfacial tension between the crude oil and the oil displacement system, so that the crude oil can be separated from the rock formations and oil sands, and be pressed to the ground together with the oil production drainage system, thereby improving the efficiency of oil production and Yield. andOBSIt can be used well in combination with ordinary hydrocarbon surfactants, which can reduce costs and improve benefits. The general dosage is0.3%about.

two:Technical indicators

Note: The essential reaction in the production process of this product is the acid-base neutralization reaction, which will definitely produce the inorganic salt sodium chloride, accounting for approximately4%, the high-temperature drying and filling process will quickly absorb moisture in the air, about1%.Marked on the market98%Most of the above are false standards.

Three: How to use

take appropriate amountOBSuse20%Dissolved in aqueous ethanol solution1%--2%, you can add a certain proportion of sodium dodecyl benzene sulfonate,K12,DemulsifierSP169etc. to help reduce the interfacial tension of the system, and at the same time can play a role in collaboratively reducing the surface tension. After the configuration is completed, the solution should be prepared on site according to0.2%arrive0.3%The added amount is added to the fracturing fluid. The specific dosage needs to be determined based on the actual situation on site or experimental results.

Four: Packaging and storage

OBSLeaving it in the air will quickly absorb moisture in the air, causing the product to clump and become difficult to dissolve. When this product leaves the factory, it is packed in vacuum packaging bags10Kilogram, small bag, barrel2The small bag is packed with a double-layer vacuum bag on the outside and placed in a round paper drum. After taking the sample, the remaining product needs to be drained of air and tied tightly with ropes. For products that absorb moisture80Celsius of water plus20%Soak in ethanol solution24hours, does not affect the use effect. This product is stored in a cool place indoors. The shelf life is calculated from the time of ordering, at least36months.

Five: Safety and Protection

OBSIt is a white powdery solid particle with a particle size of400Eyes, easily inhaled into the lungs and damage mucosal tissue. Wear masks, goggles, gloves and other labor protection tools when using. There will be no adverse reactions if it comes into contact with the skin. Just rinse with water. However, it will feel bitter when it comes in contact with the mouth. Do not swallow. Rinse immediately with plenty of water. If it comes in contact with the eyes, nostrils and other mucosal tissues, rinse with normal saline. Seek medical attention as soon as possible if necessary. This product does not burn and does not support combustion. Open flames may ignite packaging materials. Fire prevention measures should be taken.
