Series For Water Finding In High-Water-Cut Oil Wells

Research on swab test technique and wireline logging series for water finding in high -water-cut oil wells consists of the study on swab test technique and swab test logging data interpretation method. It's a new breakthrough in production profile test technology of oil wells. High-water-cut swabbing production profile logging utilizes hollow rod pump, packer, up-running preventing slip, release assembly and other downhole devices. By changing the length, stroke length and frequency of hollow rod pump, the normal and abnormal producing of pumping wells is simulated. After being run into the tubing, the logging tools make continuous survey at first and then survey down to acquire the flow rate and hold-up of every layer. So it provides the dynamic monitoring data in different production conditions. The research optimizes the logging tools and resolves the problems of the logging tools. The interpretation charts and plates are calibrated and drawn in the laboratory. It can provide the reliable reference for downhole operation by fine interpretation of logging data and calculating the oil and water production rate of every layer.Present paper main research content including the following 6 aspects:①The oil pumping mechanical well pump test looks for the water engineering research. Base on installs the technological design, the implementation method research and the consummation to the original pump testing tool.②The choice suitable logging instrument, to make the improvement to the existence question, enhances instrument's technical performance.③The scene carries on the oil pumping mechanical well pump test. Uses the optimal measuring instrument, obtains in the well the log information.④Laboratory many instrument rating data analysis, manufacture explanation chart version.⑤In the mine shaft instrument mechanism design, uses the new material and the new craft, enhances the mine shaft instrument's heat resistant pressure resistance performance.⑥Calculates precise perforated zone each sub-zone according to the log information to produce the fluid situation; The analytical study basis produces the fluid situation to carry on the work the effect.This article main research results are the oil pumping mechanical well pump test craft and the oil well logging series instrument optimal and the log information explanation method study. This research including the pump testing tool's design and the improvement, installs the craft the design, logging tools' improvement and instrument's laboratory demarcates and manufactures the explanation chart version, the log information analysis and the interpretation method. May calculate each level according to the log information to deliver the quantity, solved the high hydrous crude oil performance monitoring data to explain fine this difficult problem, will provide the precise geological parameter material for the geological personnel, the oil field measure effect will enhance further, later period developed for the oil field increases the oil precipitation to provide the measure basis, for the oil gas stable production, the production increase provided the powerful guarantee.
