针对低渗透油藏内压力传导特点及高含蜡、含胶质石油的渗流特征,研究了高效开发这类油藏的4项关键技术:早期注水,可以保持地层压力,防止油层孔隙度、渗透率降低;缩小井距可获得较好的开发效果;限制油水井停产停注时间,减小胶凝结构体系触变性的影响;利用微生物驱油,改变胶凝结构,提高油井产量
According to the characteristics of pressure transmission in low permeability reservoirs and the seepage characteristics of highly waxy and gelatinous oil, four key technologies for efficient development of such reservoirs are studied: early water injection can maintain formation pressure and prevent reservoir porosity from penetrating Rate reduction; narrowing the well spacing to obtain better development effect; limiting stoppage stoppage time in oil and water wells, reducing the impact of the thixotropy of the gelling system; using microbial flooding to change the gelation structure and improve the well production
