Swelling technology for carrying out fracturing construction on fiber
The invention belongs to the technical field of fracturing construction in development of petroleum and gas and more particularly relates to a swelling technology for carrying out fracturing construction on fiber. The swelling technology is characterized in that high-pressure air forms negative pressure through an air jet sprayer and sucks bundle fiber; the bundle fiber is metered by volume by a metering screw pump and swelled by the air jet sprayer to form silky fiber; the silky fiber is blown away into a fracturing mixing tank by using air flowing at high speed in the negative area and is mixed with sandy fluid according to proportions; and the mixed fiber and sandy fluid and fracturing fluid are pressed into an oil and gas reservoir to carry out fiber fracturing construction. A swelling technology device for carrying out fracturing construction on the fiber consists of a fiber hopper, a frequency-conversion speed-adjusting motor, a metering screw pump, an air jet mixer, a corrugated pipe, a throttle and the fracturing mixing tank. According to the swelling technology for carrying out fracturing construction on the fiber, the negative pressure area is formed by using high-speed air, and the fracturing construction is carried out after the bundle fiber are converted into the silky fiber.
