A PROPPANT IMMOBILIZED ENZYME AND A VISCOFIED FRACTURE FLUID |
摘要 |
Provided is an enzyme immobilized on a proppant. Also provided is a viscofied fracture fluid 1 formed by combining a solid proppant, a binding agent and an enzyme to form a proppant-immobilized enzyme 2, mixing the proppant-immobilized enzyme 2 with a second proppant 3 to form a heterogeneous proppant pack 4 and mixing said heterogeneous proppant pack 4 with a gelled liquid fracturing fluid 5 to form the viscofied fracture fluid 1 containing the heterogeneous proppant pack 4. The viscofied fracture fluid 1 containing the heterogeneous proppant pack 4 is pumped 6 into a subterranean zone 7 to form one or more fractures therein. The proppant-immobilized enzyme 2 that is part of the heterogeneous proppant pack 4 has the dual purpose of propping open the subterranean fractures and reducing the viscosity of the viscofied fracture fluid. |
