摘要
低渗油田储量在我国未动用石油地质储量中所占比例越来越大,低渗油田经济、有效开发对我国石油工业的可持续发展至关重要。随着低渗油藏不断开采,地层压力不断下降,岩石净有效覆盖压力不断增加,岩石孔隙产生变形,油藏流体渗流不再遵循达西渗流规律,随着油藏的进一步开采,储层应力敏感增强,应力敏感对油藏的影响不容忽视。文章通过对低渗油藏考虑应力敏感效应已否进行分析比较,研究应力敏感对低渗油藏开发动态影响。
With the constant low permeability reservoir ex-ploitation,formation pressure drop,rock net effective coverage pressure increase,the rock pore is resulted in deformation and the seepage flow of fluid in low permeability reservoir no longer fol-lowed Darcy flow law.With the further exploitation of reservoirs,reservoir stress sensibility is enhanced,the influence of stress sen-sibility on reservoir is very important.Based on the analysis of low permeability reservoir stress sensibility,the dynamic effect of stress sensibility on low permeability reservoir development was re-searched.
