低渗透断块油藏合理注采井距研究
摘要
Abstract
Because of low reserves abundance, low permeability, starting pressure gradient, it is very hard to establish effective displacement pressure system for the low permeability and fault block reservoir. And, because of small oil area, complex shape, belonging to narrowband oil field, it is also very hard to implement regular well pattern and adjustment in later stage. Therefore, it needs to deploy wells successfully in the beginning and it must select reasonable spacing for the low permeability and fault block reservoir. Using the drilling cores of oil field, and by means of physical simulation experiment, we measure the starting pressure parameter. With laboratory findings, theoretical analysis and numerical simulation, we study the effect on effective spacing, rational spacing, and well pattern of starting pressure gradient and reservoir conditions. Combined with physical simulation experiment, reservoir engineering theory derivation and numerical simulation, we propose one method to calculate reasonable spacing and dispose well pattern suitable in low permeability and fault block reservoir. The study results are applied to actual oil field and obtained good development performance.关键词
