Based on the similar dimension,the method of measuring the fractal dimension was brought forward in natural low-permeable cores through traditional intrusive mercury data or image analysis,and the calculated formula for the dimension was achieved.

Experimental study of the impact of fluid flow on low permeability core resistivity

Experimental study on coupled flow through low permeability rock under confining pressure;

Non-Darcy flow of single-phase water through low permeability rock;

The effect of fluid-solid coupling on the seepage in low permeability rocks was measured for sandstone from the Changqing oil field on an FDES-641 triaxial system.

An experimental study on oil migration and accumulation in low-permeability sandstone;

Based on the comprehensive geological study of Niu-20, Chun-41, Zhuang-74 and Daluhu low-permeability sandstone oil pools, the research content and method of the geological model on the reservoir heterogeneity of low-permeability sendstone oil pools in Shengli oil district were sumarized systematically in this paper.

Threshold pressure gradient of low permeability sandstone;

The poor producing degree and the economic benefit of the low permeability sandstone by vague injection-production is caused by changeful sedimentary microfacies and high intra-layer and plane heterogeneity in whole oil reservoir set.

The structural fractures in fractured low permeability sandstone reservoirs have great effect on displacement efficiency.
