The, fracturing fluid, should meet the characteristics of little filtration, strong sand-carrying capacity, low friction, low residue, and easy flow back . During the, fracturing, process, a large amount of, liquid, needs to be, pumped, at the bottom of the well to rupture the formation to produce fractures, and a large amount of, fracturing fluid, will enter the coal reservoir.

Initially, the carrying fluid for high viscosity gravel packs was refined ail or lease crude that had viscosities ranging from 200 to 1000 cps. Considerable success with sand control has been achieved using this system; however, friction pressure, disposal problems, and cost lead to the development of wore practical viscous water-based carrying fluids.

Regardless of the method, proper sand management is the vehicle needed to balance sand control with the desired production results through optimized completions.Gravel packing is a common sand-exclusion technique that has been used since the 1930s. 19 This procedure involves pumping a designed slurry, comprising gravel of a specific size and an appropriate carrying fluid, to fill the annular space …

pressure plate. Components of the pumping cartridge are an elliptical cam ring, a slotted rotor splined to the drive shaft and twelve vanes fitted to the rotor slots. As the rotor is driven by the driveshaft, the vanes generate fluid flow by carrying fluid around the elliptical ring contour (see Section III). Fluid enters the cartridge through the inlet

Sand is transported by both mechanical and nonmechanical means, and sand transportation is controlled collectively by the auger conveyor at the bottom of the blender and by adjustment of the opening of the butterfly valve and, thus, the fluid-infusion rate of the sand-mixing tanker.

However, in most cases, only 20-40% of the ,carrying fluid, flows back to the surface and the rest remains deep in the ground. Initially, the technology used 20,000 to 80,000 gallons of water per well, but today’s advanced fracturing techniques can use up to 8 million gallons of water and 75,000 to 320,000 pounds of ,sand, (proppant) per well.
