Abstract: The systemic study on completion string, sand control technology and cold production have been carried on aiming at the high viscosity of the reservoir in member 3 of Shahejie Formation and sand production. Field test show that matching technology of large-aperture, deep-penetration, high shot density, packing under high pressure together with cold production of screw pump can effectively solve sand control in siltstone and fine sand reservoir and make the viscous oil production easily. It has great significance to the same reservoir development.
