![]() Although slickwater fracturing has strong fracture-making capacity and low economic cost, the fracturing fracture is easy to close due to strong filtration loss in a reservoir, and the filtration loss of fracturing fluid needs to be compensated through high discharge capacity, so that the pumping requirement and the water resource requirement are high, and chemical additives in the fracturing fluid can cause certain pollution to a stratum. The reasons mainly include two aspects, namely that the width of the hydraulic fracture is not enough (the width of the fracture near the wellbore is a few millimeters, the width of the fracture far away from the wellbore is narrower along with the extension of the fracture, the width of a micro-fracture for connecting is narrower, and the width of the fracture is micron or submicron grade), and the proppant is difficult to embed and secondly, the slickwater fracturing fluid is low in viscosity and insufficient in sand carrying capacity, and the propping agent is easy to rapidly precipitate and gather at the bottom of a crack around the well. However, the slickwater fracturing technology in the prior art generally has the problems that the proppant filling in the hydraulic fracture is not in place and the permeability is difficult to reach the standard. ![]() using additives to drilling or well treatment fluids for inhibiting clay or shale swelling or disintegrating C09K2208/00- Aspects relating to compositions of drilling or well treatment fluids.C09K8/845- Compositions based on water or polar solvents containing inorganic compounds.C09K8/84- Compositions based on water or polar solvents.compositions of proppants used to keep the fractures open C09K8/80- Compositions for reinforcing fractures, e.g.C09K8/665- Compositions based on water or polar solvents containing inorganic compounds.C09K8/66- Compositions based on water or polar solvents.C09K8/62- Compositions for forming crevices or fractures.C09K8/60- Compositions for stimulating production by acting on the underground formation.for completion or for remedial operations C09K8/00- Compositions for drilling of boreholes or wells Compositions for treating boreholes or wells, e.g.C09K- MATERIALS FOR MISCELLANEOUS APPLICATIONS, NOT PROVIDED FOR ELSEWHERE.C09- DYES PAINTS POLISHES NATURAL RESINS ADHESIVES COMPOSITIONS NOT OTHERWISE PROVIDED FOR APPLICATIONS OF MATERIALS NOT OTHERWISE PROVIDED FOR.Google has not performed a legal analysis and makes no representation as to the accuracy of the date listed.)
