Well pattern deployment and optimization in low-permeability glutenite reservoirs: A case of glutenite reservoirs in Sha 4 member of Yong 1

Low-permeability glutenite reservoir pattern deployment and optimization are important for its efficient development. In this paper, taking the in Sha 4 member of Yong1 as an example, numerical simulation method percolation theory used to study influence sediment source in-situ stress direction on well deployment. Then, low-permeability was optimized, finally optimized parameters designed. It is concluded that ① When injection wells deployed along stress, injected water can easily form linear displacement, which effectively increase volume achieve a best development effect. ②The 5 point has effect, it belongs strong production patterns, solve problem poor ability reservoirs. ③For anisotropic reservoirs, deformed patterns be equilibrium displacement. The injection-production distance different directions mainly controlled by permeability.
