摘要: 通过对克拉玛依二中区三采试验区粒度分析资料的整理分析发现,冲洗沉降法的分析结果明显失真(尤其是泥质含量),筛析法分析结果精度高,与油藏实际比较吻合。由于砾岩储层泥质含量比较低,其对储层物性(渗透率)的影响并不明显。

Abstract: Detailed investigation of the grain size analysis data in tertiary pilot area, middle District No. 2, Karamay oilfield got the idea that the result from flushing precipita-tion became apparently distorted. especially the shaly content, while the data from sieve .analysis accord well with the actual conditions of the reservoir. Because of low shaly con-tent in conglomerate reservoir, it doesn't obviously affect the reservoir permeability.
