灰色理论应用于储层综合评价的方法研究

The Method Research of Reservoir Evaluation by Grey Theory

储层综合评价是对储层特征的全面总结,它对指导油气开发具有重要意义。文15块沙三上段主力油层储层综合评价研究是以取芯井地质、测井资料为依据,在沉积相、储层基本特征研究的基础上进行的。利用灰色理论对储层的含油程度、分布状况、物性、产能大小及非均质性作出全面的综合评价,划分出一、二、三、四,四类储层,明确了各类储层的展布特征,一、二类储层在该区主力油层中分布发育规模范围大,是该区油田最为有利的开发层位及相应井区。

Reservoir comprehensive evaluation is a whole summary to the reservoir characteristics.It has great significance to the overall guide of oil and gas development.The evaluation research for Es_3 reservoir in Wen15 block is according to the research of core well and logging data,based on the research sedimentary facies and the reservoir basic characteristics.In this paper we use the grey theory to evaluate the reservoir characteristics such as oil saturation,distribution,physical property,capacity size and anisotropy.Four kinds of the reservoir is make off.Their distribution characteristics are also cleared.The first and second reservoir is developed in scale range in this region,and these corresponding area are the most favorable layers for the future development.
