Study For Classification And Management Of SaNan Production Area's Oil And Water Well

SaNan production area is in the late of production, its high degree using of high-quality oil reserves and the main oil layer accelerated natural degression and increased the rate of water content, and it shortened the period of validity of measures and increased the difficulty of stable production and gradual increasing production. Under some objective conditions, such as the heavy mission of crude oil production and the annual maintenance of wells so many times, it has not yet operational standards and norms for oil and water wells, and classification of fine management, this will ultimately affect the effectiveness of oil field development, how to manage SaNan production area effectively is a very important topic which placed in front of producers and researchers. Among them, the important key to manage oil and water well effectively is to take classification and sophisticated management of oil and water wells. Therefore, it will make important theoretical significance and practical application value to explore a scientific classification method of oil and water well and classify the oil and water well, on the basis of that, propose the operational measures.This article raises the background and significance of studying the oil and water wells, refers to the importance of the classification on the SaNan production area, summarizes the theoretical studies at home and abroad from the standpoint of increasing development benefit of oil field, from the goal of classifying and managing oil and water well, and from the target of SaNan production area in Southern District. Secondly, it describes and analyses SaNan production area in Southern District, and introduces the related concepts. Next, it constructs the classification of indicator system of SaNan production area in Southern District, and makes use of plate method and mathematical statistics methods to classify oil and water well, and derives classification criteria, while applying K-means cluster analysis methods to classified test. Finally, according to the classification of oil and water well, this article presents an effective management method.
