Cyclic waterflcoding in naturally fractured reservoirs has been tested and practiced abroad for years, and controversial conclusions have been reported by different operators. Though a good deal of experimental and theoretical studies has been made, no relatively rigorous and complete theory and computational technique have been published so far. As a result, the reservoir behavior as a whole during cyclic mater-flooding is not fully understood, and no prediction can be made with proper accuracy, and, therefore, optimization of the development program cannot be devised. In this paper, the theory of fluid displacement in a medium with double-porosity proposed in reference [5] is further developed, and imbibition equations suited to any type of water flooding are derived, and a computing method to predict the performance of naturally fractured reservoirs during cyclis waterflooding is presented. Preliminary study based on the above theory shows that the effectiveness of the cyclic water-flooding depends on the specific conditions of every reservoir. Even if only the effect of imbibition is considered, the application of cyclic waterflooding under certain reservoir conditions will be of considerable benefit to the development, when controlled properly.

A method based on the principle of soil water dynamics for estimating hydraulic conductivity using horizontal column infiltration is described. Soil sorptivity is found from the ratio of the cumulative infiltrated water and the square root of time. With the known relationship between sorptivity and water head applied at one end of the column, both saturated and unsaturated hydraulic conductivity can be determined. The proposed method has clear concept and the required equipment is simple and easy to operate.
