摘要:
为指导致密油藏的勘探与开发,以鄂尔多斯盆地陇东地区长7致密砂岩储层为例,基于应力敏感实验,开展了地层孔隙度、渗透率随净上覆压力变化规律研究。实验结果表明,随着净上覆压力不断增加,地层孔隙度和渗透率都有不同程度减小,但减小幅度不同。一元二次方程能较好地描述孔隙度、渗透率随净上覆压力的变化关系,由此建立的孔隙度、渗透率计算模型能有效弥补室内实验的有限性和局限性,为油田的勘探开发提供依据。
Abstract:
In order to better guide exploration and development of the tight oil reservoir,based on the stress sensitive experiment,this article took the Chang7 tight sandstone reservoir as an example and carried out studies on changes in porosity and permeability with the net overburden pressure in Longdong area of Ordos Basin.The experimental results showed that with the increase of the net overburden pressure,formation porosity and permeability decreased in different degree,but the decreased range was different.A quadratic equation can be used to describe the variation relationships in porosity and permeability with the net overburden pressure,and the established model for calculating porosity and permeability can compensate for the finiteness and limitations of laboratory experiments effectively and provide basis for the oilfield exploration and development.
