Introduction

The tester is applied to measure fracture conductivity based on API standard. It can simulate downhole condition and detect flow conductivity of fractured interval under a certain closure pressure to evaluate the proppant. Besides, it provides some indispensable parameters for fracturing design and effect prediction. Thus, it is a necessary instrument to guide production and carry out laboratory investigation.
