Abstract

During steam stimulation, micro crack can lead to steam channeling and decrease steam ratio and quantity at the bottom. According to the theory of elastic mechanics and thermodynamics, the micro crack calculating model was established. Micro crack width increases with the increasing of injection steam temperature. On this basis, select the bridge plugging material as micro crack plugging material. Basing on fractal theory, optimization model of plugging material was established. According to case study, the micro crack width increases with the increasing of injection steam temperature. When the steam temperature is 330?"?, the mass ratio of cement, micro-silicon and sand is 100:14.23:35.79. This study will provide the theoretical basis for micro crack plugging in steam stimulation wells, and provide technical guarantee for improving steam stimulation effectiveness.
