直罗油田长6砂层组储层特征研究

Study on Reservoir Characteristics Chang6 Sand Group in Zhiluo Oilfield

直罗油田有着很好的生油潜能,但是由于低孔低渗使得开发难度大大提高。本文从砂层组储层特征研究着手,分别对长6的岩石学特征,孔隙结构特征,储层敏感性及渗流特征进行了研究,针对岩石颜色、特征、填隙物等进行了分析。

Zhiluo oil field has a very good oil potential, but it is difficult to develop the oil field due to its low porosity and low permeability. In this paper, the characteristics of reservoirs in the sand layer were studied. The petrological characteristics, pore structure characteristics, reservoir sensitivity and seepage characteristics of Chang 6 wereinvestigated respectively, and the rock color,characteristics and interstitial materials were analyzed.
