摘要
低渗透油气藏的合理开发方式和油井工作制度的确定,能为该类油气藏有效开发提供指导.将拟压力应用到变形介质中,引入渗透率变异系数,推导了考虑渗透率影响的产量公式.实例应用结果表明:计算结果与实际采用的生产压差的相对误差为5%,产量相对误差为3%.
The reasonable development program and working system were established in the low permeability reservoir; as a result the guideline for this type of reservoirs was provided. The application of the pseudo-pressure was quoted in the deformed media reservoir; furthermore, the permeability modulus definition was used. To simplify the production equation, only the permeability effect was considered. In the end, an example was given to prove the reasonable productivity in the field.
