    Abstract
  • As a new CO2 fracturing technology, the normal pressure sand mixing quasi-dry fracturing technology inherited the unique advantages of the CO2 fracturing technology. The normal pressure sand mixing quasi-dry fracturing technology does not necessitate special closed sand-mixing equipment and the sand can be mixed at normal pressure. With this fracturing technology, sand is mixed with ease, and drag reducing and sand carrying can be done in an integrated manner. In this paper the background, technical ideas and advantages of the normal pressure sand mixing quasi-dry fracturing technology is set out and analyzed, and the performance of the products and the quasi-dry fracturing fluid are systematically evaluated and studied. Meanwhile, based on the present field application of the normal pressure sand mixing quasi-dry fracturing technology, technical support for the promotion of this new fracturing technology in the future is provided.
