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.

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.

Layout Design of RF Front-End for 433MHz ASK Receiver;

Layout Design & Verification of Coprocessor;

A transfer methodology from 3D model to 2D mask layout in MEMS CAD field was put forward after studied respectively the format of the standard 3D model file and the 2D mask layout file.

Taking account of the effect of wellbore storage and the influence of non-Darcy effect,the relationship between dimensionless time and dimensionless pressure has been derived and theoretical plate of gas and water two-phase flow has been mapped out which provides a theoretical basement for well test int.
