Research of Reinjection Technology and Demonstration of Neogene Porous Guantao Reservoir in Binhai New Area, Tianjin

摘要

The author analyzes the reasons to reduce reinjection rate through reservoir sensitivity analysis, blocking reasons analysis, the reinjection well completion technology and ground equipment and techniques. The physical blocking is the main question of reinjection blocking. The well completion technology is pivotal to keep sustainable reinjection, and the standard ground reinjection system can avoid physical and chemical due to geothermal fluids reinjection. Using successful well completion technology and standard ground reinjection system, the reinjection quantity is 100-120 m~3/h which is a big reinjection breakthrough of porous reservoir in Binhai New Area, Tianjin.
