1. Overview
Fracturing operation is one of the main means to increase the production of low permeability reservoirs in oilfield production. The stimulation effect of fracturing operation is closely related to the conductivity of the propped fracture, which depends on the width of the fracture and the permeability of the proppant after the fracture is closed. Therefore, only by optimizing and controlling the quality of proppants from different sources before fracturing operation can the best construction design be ensured. The fracture conductivity tester is an instrument for optimizing and controlling the quality of different proppants before fracturing operation.
