Based on the process requirements for preventing sand production from the formation and proppant flowback, the consolidated sand can be cured in a formation environment of 20-150°C. The artificially formed wellbore wall through curing has excellent flexural properties, which can effectively prevent sand production from the formation and proppant flowback. At the same time, the cured artificial wellbore wall also has good permeability, forming a conductive passage for oil, gas, and water.
The consolidated sand produced by our company is divided into two sub-products: high-temperature curing and low-temperature curing, both of which can achieve excellent sand prevention effects. High-temperature curing is suitable for formation temperatures above 50°C, where the consolidated sand can undergo self-reaction curing under high-temperature conditions, with a curing time not exceeding 72 hours, and the strength of the cured artificial wellbore wall can reach more than 8MPa. Low-temperature curing is suitable for formation temperatures between 20-50°C, where the consolidated sand undergoes low-temperature induced curing under the action of a matching enhancer, with a curing time not exceeding 72 hours, and the strength of the cured artificial wellbore wall can reach more than 10MPa.
