The comparison is chiefly made from the following three aspects: Ereignis and Tao;lending an attentive ear to Sage and obtaining Tao by observing;and,transcendental language used to express the unspeakable and the assumption of ideal living condition.

Inter-Gegend which we call“inter-Ereignis”is the way appearing uni-Gegend,as“separating”for“not seperating”and is the way to uni-Ereignis.

In the paper,the discriminant function is derived from the Fisher principle to distinguish large pore paths in sandstone oil layers based on logging curves.

Through studying the well logging principle,the interpretation of water-out zones,and the formation mechanism of the large pore path, we find the logging response characteristics when there are large pore paths.

Characteristics and controlling factors of high capacity channels of reservoirs at high water cut stage: A case from Block Hu 12 of Huzhuangji Oilfield;

The application of the micro material inter-well tracing technology in recognizing high capacity channels in oil layer;

Simulation experiments of the formation process of high capacity channel in a sandpack model with glass plate;

Based on mechanics principles, considering the interaction between reservoir fluid flow and deformation, the interaction between porous flow and pipe flow in big channel, mathematical model to simulate sand production is built.

A coupled model of seepage and pipe-flow for sand production from big channel in unconsolidated reservoir is deduced based on fluid mechanics and rock mechanics.

On the basis of the analysis of large number of tracer production curves, the wateredout zones can be divided into three types: thiefzone, big channel and the extra big channel.
