The fracturing fluid uses BCG-8, an improved version of BCG-1, as the fracturing fluid thickener. It has strong viscosification ability and can dissolve in water to form colloidal solution in low pH environment. It can cooperate with the additive B-55 to form a strong spatial structure, so that the solution has a strong viscoelasticity. The gel is compatible with carbon dioxide, allowing the gel to form a foam with carbon dioxide, greatly improving foam stability. There is no residue after liquid phase breaking, which is conducive to the transformation of low permeability, water sensitive, water locked and fractured reservoirs.
1:The product has all the characteristics of a foam fracturing fluid;
2:Can be dissolved at low pH value (pH =5.0 ~ 7.0) to form an aqueous solution for fracturing fluid base fluid；
3:Can cooperate with other functional additives to form high viscoelastic gel under the condition of low pH value (pH =5.0 ~ 7.0), which can be used as sand carrying fluid in fracturing construction；
4:The gel can form a foam with carbon dioxide and is used for carbon dioxide foam fracturing;
5:The liquid phase of the foam fracturing fluid does not contain glycans, and bacteria will not breed in the ground and formation. This prevents fracturing fluid biodegradation or formation clogging with biogel, which reduces fracture conductivity;
6:Water dilution, organic matter addition, oxidation can make the fracturing fluid break;
7:The gas and liquid phase of foam fracturing fluid does not contain residue, the residue content is low after breaking, and the damage of conductivity is generally less than 10%;
8:The product is especially suitable for fracturing of ultra-low permeability, water-sensitive, water-locked and fractured oil and gas reservoirs.
