The application of the improved Tong's chart in the low permeability oil reservoir

Improvement of Tong's Chart and application in forecasting water cut of reservoir

The optimum plate of drill string assembly and drilling parameter is made.

Based on the brief introduction of the grotto art database of Dunhuang Studies digital library,this paper expounds the of the plate and carries out an in-depth research on the types,hierarchy and logical system of these keywords,then it discusses the main problems in the extraction process emphatically.

Theoretical Basis and Method of Establishing Φ_D-S_D Water Flooding Degree Distinguishing Chart;

According to the geology characteristics of Xifeng strata and by analysis and comparision, the paper summarized the classification standards of interpretation evaluating chart and reservoirs in Xifeng Oilfield with two evaluation methods for gas composition on the basis of analyzing the low coincidence rate of interpretation and evaluation for conventional gas ratio technique and 3H method.
