The article analyzes the advantage and disadvantage of part lacking fidelity searching algorithm, based on early ending technology thought. Given the disadvantage of the partial distortion search (PDS) algorithm, it brings up one kind of improved method which is similar to it. The improved algorithm also calculates sum of absolute difference (SAD) once within a row and add it to the block pixel SAD, but the two disadvantages of part lacking fidelity searching algorithm has been improved. The results of related experiment show that the early termination of fine granularity adaptive threshold and search points in the levels of early termination of the introduction of adaptive strategies used in the paper improves the speed moving estimation. This will promote the transmission quality of network video frequency to a new higher grade.

With the mature technologies and products, the next generation network has been more and more concerned in China. Chinese main telecom operators are beginning to associate test or structural network in order to expand their market. The article advances a new theory to solve the failure of the current communication networks that is the implementation of the passive caller resumption. It settles the problem of the passive caller resumption by part of recipient resumption and traffic. This brings forward a better plan to resolve the failure user isn't the recipient user. It can make the passive caller return to normal in one second. This is the positive promoter action for perfecting the next generation network and it makes the next generation network a further improvement on the quality.

An accurate interpretation of the fluid production profile is the essential scientific step required for the dynamic monitoring and management of a reservoir. Currently, an accurate interpretation of conventional logging is generally available for vertical wells. However, high-accuracy interpretation is still a blank for horizontal wells, especially for those wells with low production. Therefore, it is of great importance to develop a new model that can efficiently improve the interpretation accuracy of horizontal wells' production profiles. Practically, it was observed from experiments that, for multiphase flow in a horizontal well, the flow pattern changes significantly with the varied inclination angle along the well trajectory. This is because the flow pattern is critically related to the flow rate and the measured phase flow data (i.e., the production data of oil, gas, and water), which varies with the inclination angle along the horizontal well trajectory. Based on the above observations, a new methodology is proposed to interpret horizontal wells' production profiles with the same inclination angle. A comparison of the measured data and numerically calculated results indicates that the newly established method can significantly improve the interpretation accuracy of horizontal wells' production fluid profile. The interpretation method is, therefore, enriched by production logging for different types of wells. By comparing the experimentally measured data and the calculated results, the newly established method is indicated to be capable of significantly improving the interpretation accuracy of horizontal wells' fluid production profile. The interpretation method is further extended to production logging for different well types. By applying this new methodology, the main water-producing layer can be precisely identified to prevent and control the water burst from horizontal wells as well as the formation of water plugging. Consequently, oil and gas recovery can be effectively enhanced.
