According to the needs of drilling technology in petroleum industry, our company has successfully developed soluble fracturing ball suitable for use in oil drilling operations, which can meet the needs of petroleum engineering technology after the experiments and tests of oil and gas field users. In order to expand the application field, our company has carried out different process treatment on the material, which can be processed to meet the different construction needs of the soluble fracturing ball.
Material characteristics: It can be dissolved in water containing electrolyte, insoluble in oil media. The rate of dissolution depends on the temperature used and the structural characteristics of the application; wherein the specific gravity is 1.5g/cm3-1.8g/cm3, the maximum working temperature is 200 degrees, and it is suitable for water wells and gas wells.
In 3% potassium chloride aqueous solution, the temperature of 50 ° C is 63.5mm before dissolution, and it shrinks to 50mm 48 hours later and 35mm 96 hours later. If the temperature is higher, the reaction speed will be faster. The surface of the ball is coated with a temperature control film of 0.05mm thickness during fracturing, and the water temperature is 40 ° C during fracturing. The dissolution rate of the ball is gradually increased, and the ball has been tested at a pressure of 70MPa for several times to meet the needs of the field for multi-stage fracturing.
