WebA diagnostic method of analyzing dynamometer cards is being used in production operations in Venezuela, in the United States and in Canada. Shell Canada first utilized the diagnostic technique in Oct., 1963. To mid-year 1966 approximately 800 cards have been analyzed from more than 300 wells being pumped in western Canada and the diagnostic ... WebApr 15, 2024 · According to the actual measure of downhole pump dynamometer card and the surface dynamometer card, the actual equivalent damping coefficient of the sucker rod can be estimated. Next, the relevant parameters of oil wells in Xinjiang Karamay Oilfield are taken into ( 55 ) and Zhang Qi formula to estimate the equivalent damping coefficient of ...
WebFeb 7, 2013 · Downhole working conditions of sucker rod pumping wells are automatically identified on a computer from the analysis of dynamometer cards. In this process, … WebThe downhole pulsation dampener completely removed the fluid inertia effects. Dynamometer cards showed a dramatic difference in shape between the "before" and "after" cases.

WebSummary The pump dynamometer card is a direct reflection of the operating conditions of the downhole pump, which is important for the diagnosis of sucker-rod pumping systems. In this paper, we propose a novel diagnostic method based on the estimation of the parameters from the polished-rod load vibration signal of sucker-rod pumping systems in ... WebA data sampler option captures real-time information for generating torque, velocity, and position plots as well as surface and downhole dynamometer cards. A data logger collects time-stamped fault, warning, and event logs that can be viewed through the keypad/display, uploaded to a personal computer, or retrieved by a network server.
WebDec 31, 1996 · The surface dynamometer card (SDC) is a plot of the load versus the pumping cycle measured at the polished rod. The SDC shape is assumed to reflect the actual pumping conditions. However, SDC is a composition of the actual downhole pump dynamics and the noise added during the information transmission along the sucker rod.
