Abstract

According to the temperature distribution of water injection well-bore in highly deviated wells under different conditions and unstable temperature field heat conduction principles, a true three-dimensional model was established to analyze the law of variation on temperature of highly deviated wells during the water injection process, and to analyze the factors that influence the water injection well-bore in highly deviated wells; this can improve the computational accuracy of the transformation of water injection string made by the temperature, and help us predicate the transformation of water injection string more accurately during the production process. The results show that the temperature distribution of highly deviated wells are greatly affected by water injection inlet temperature or injection of water inlet temperature, water injection rate, and water injection time. With the temperature field model of highly deviated wells made in this paper, the construction quality and oil production can be highly improved by reasonably controlling the temperature. All the findings which have been obtained form a theoretical basis and the experimental research for the development of mechanical analysis simulation software have been used to calculate temperature distribution and variation of water injection string in highly-deviated wells and have a great theoretical significance and practical value.
