Production Wells Dynamics And Measures Real-time Monitoring Technology Theory And Applied Research

The real-time monitoring of production well is the most important mean to understand the performance of the well, so it is also the main job in the development of the reservoir. In order to improve the production rate, the acidizing, water plugging and injection profile adjustment often be taken on the well spot. So that to find out the effect of the measure is a urgently needed by the engineer. Based on the study to real-time monitoring performance & stimulation of the production Well, this paper development a suit of technique about real-time monitoring of production well and the work enrich the dynamic monitoring technology of oil filed.Based on systemic study the development and tendency in the filed of production well real-time monitoring The mainly innovation works of the paper can be sum up to the following several point as:1. Design and development the real-time monitoring instrument, which consisted of the, real-time collection and display synchronization and the storage of the data. The instrument can control collection frequency of the data, and realize the serial communications between the instrument and the host computer. The instrumental has stable nature, it can meet the demand of real-time monitoring in the acidizing, water plugging, injection profile adjustment and well testing. In a sense, the instrument make up the disadvantage that testing apparatus in being can not meet the request of oil filed or its expenses is too high to use.2. The chief work of the paper is to investigate the complexity of acidizing treatment processing and the importance of the optimize treatment through real-time monitoring. Analyzed reaction mechanism of the fluid acid and formation rock, studied the optimized design for the sandstone matrix acidizing treatment, those study revealed the monitoring method and the mathematical theory of acidizing treatment processing. The acid volume and the wellhead injection pressure monitored during acidizing process can be used to analyze the variety of skin factor. The water plugging & profile adjustment real-time monitoring method is given in this paper. Based on the study of basic technique of water plugging & profile adjustment, the paper study the phenomenon of lower permeability of sand formation caused by water plugging & profile adjustment Based on the plugging Coefficient function, the water plugging & profile adjustment...
