Evaluation of non-Darcy flow effect in gas well considering influence of flow boundary;

Characteristics of non-Darcy flow velocity of oil-water phases in extra-low permeability reservoirs;

Experiment on the influence of boundary layer on the Non-Darcy seepage law;

According to the results of mine test and lab experiment,non-Darcy seepage flow will occur during the exploitation of reservoirs with low permeability and extra-low permeability,especially the crude oil seepage flow, which will have a obvious startup pressure gradient.

A new skin factor model for open hole completion of horizontal wells under Non-Darcy flow;

Consolidation computation of aquitard considering non-Darcy flow;

New deliverability equation for gas wells with high velocity non-Darcy flow;

The result shows that waterflood frontal movement of non Darcy flow is fast, resulting in earlier water breakthrough; the higher the injection rate, the faster the frontal movement, and the earlier the breakthrough.

Amathematical model for Non Darcy flow of two phase fluid through anisotropic double porosity media with a vertically fractured well working is established.

During the process of the deviation,it considers the effect of non Darcy flow and the anisotrophy of gas layers on the productivity of horizontal wells.
