Study on optimization formula and infiltration regularity for major auxiliary burden of sugar-vinegar garlic;

The development of conception of permeability coefficient is introduced in this paper through the generation of Darcy s formula and study on the physical bases of K, testing for the real limitation of seepage law and practices of Dupuit s equation for waterwell.

Till now, there are such theories as Reliance theory, Rule of Law theory, Alternative Rule of Law theory, Legal Osmosis theory, and Economic Efficiency theory.

Study and application of the reservoir seepage rule in E_2d of Huangque oilfield;

The grouting seepage law of fractured seam was studied.

The gas seepage law in a single fracture under 3D stress is studied and the following conclusions have been made:(1) the tangent deformation has the same effect as normal deformation on fracture seepage law,and (2) gas seepage law is different from water seepage law.

The experiment analysis of gas seepage law in a single fracture under 3D stress is studied, theinfluence of tangent stress on the seepage law is focused, and the following conclusion has been made: the tangentdeformation has the same effect as normal deformation on fracture seepage law, In the end, an experientialformula of gas seepage law in a single fracture are brought forward.

Experimental study of percolation in low permeability reservoir based on steady flow method;

On the basis of percolation mechanism analysis for low permeability reservoir,average water cut has been obtained through analyzing the impact of starting pressure gradient on percolation,and thus matched relative permeability curve.
