油层非均质性对油田开发的影响研究

Research on the Impact of Reservoir Heterogeneity on Oilfield Development

在石油开采过程中,油层非均质性是经常遇到的难点问题之一,严重制约了油田的高效开发。油层非均质性主要分为微观非均质性和宏观非均质性两种,油层微观非均质性主要是指油层孔隙类型和喉道类型之间的差异,宏观非均质性又分为层间非均质性和平面非均质性。油层的非均质性会产生层间干扰和单层突进等问题,这些问题的出现使得石油开采难度加大,因此,要在开采石油的过程中提高效率,需要解决油层非均质对油田开发带来的影响。通过对油层非均质性的表现和现象进行分析,探讨了油层非均质性对油田开发的影响,以期能够为提高油田开采效率和水平奠定基础。

In the process of oil exploitation,reservoir heterogeneity is one of the difficult problems often encountered,which seriously restricts the efficient development of oilfields.Reservoir heterogeneity can be divided into two types:micro heterogeneity and macro heterogeneity.Micro heterogeneity mainly refers to the difference between reservoir pore type and throat type,while macro heterogeneity can be further divided into interlayer heterogeneity and plane heterogeneity.The heterogeneity of the reservoir will produce interlayer interference and single-layer outburst,which make the oil exploitation more difficult.Therefore,in order to improve the efficiency in the process of oil exploitation,it is necessary to solve the impact of the heterogeneity of the reservoir on the development of the oilfield.Based on the analysis of the performance and phenomenon of reservoir heterogeneity,the influence of reservoir heterogeneity on oilfield development is discussed in order to lay a foundation for improving the efficiency and level of oilfield exploitation.
