Product description

Clean sand-carrying fluid is a water-based fluid system formed by a combination of various surfactants on molecule level . In the static state, the fluid has a lower viscosity. Under influence of Ca2+ , the viscosity of the liquid is greatly increased, and the gel is formed . At 25 ° C, the viscosity of the 1% aqueous solution is about 10 mPa·s. When Ca 2+ is applied, the viscosity can be raised to 150-200 mPa·s to form a gel, and the gel can be broken encountered with crude oil . This characteristic of cleaning the sand-carrying liquid can use formation water (oil field sewage) containing a higher concentration of Ca2+ as a solution, and maintain a high sand-carrying ratio during the sand-carrying process.And after the sand-carrying operation is completed, the viscosity is lowered due to the system being stationary and the liquid is easily discharged from the formation. In addition, since the clean sand-carrying liquid is a multi-molecular combination system of surfactants, the system has large cohesive energy and small force on the rock surface. so the retention in the formation is poor and no residue is left, and the flow-back is easy, and damage to the formation is little. The clean sand-carrying liquid also has a good washing effect and an emulsification and viscosity-reducing effect on crude oil.

Usage method

(1) during the usage, the cleaning liquid carrying liquid has no special requirements compared with other types of sand carrying liquid;

(2) The optimum operating temperature for the cleaning sand-carrying liquid is between 25 and 65 °C;

(3) the sand carrying ratio of cleaning sand carrying liquid can be determined according to the site construction requirements.

(4) The cleaning sand-carrying liquid needs to be configured with formation sewage, or with water containing 2%~5% Ca2+, the dilution ratio being 80-100 times.
