Analysis on Optimization of Adjusting Parameters Method for Pumping Unit in Y Block

In the daily production of oil field, the theoretical displacement of pumping unit can be changed by optimizing and adjusting the production parameters of pumping unit, that is stroke and frequency of stroke, and then the pumping intensity can be adjusted to ensure the efficient production of oil wells. After years of development in Y block of X Oilfield, the production conditions of production wells are constantly changing and the operation rules are becoming more complicated due to various factors such as the demand of development situation, the change of injection-production mode and the change of replacement mode. The simple adjustment mode of increasing parameters with high flowing pressure and decreasing parameters with low flowing pressure cannot effectively achieve the purpose of adjusting the pumping intensity, resulting in some wells with no drop in flowing pressure with parameter increasing and no rise in flowing pressure with parameter decreasing, as well as a significant increase in energy consumption of the system after adjustment. At the same time, with the demand of controlling production cost and reducing cost and increasing efficiency, improving production well system efficiency and reducing energy consumption have become the key tasks of oil recovery engineering in recent years. As energy-saving equipment gradually becomes popular, the potential for energy saving from process modification gradually decreases. How to optimize and reduce energy consumption under the most basic production management mode has become a new research direction. In this paper, we analyze the optimization method of production parameters with the highest pump efficiency as the core, and through the comparison of theoretical calculation and experimental results, we find the way to achieve efficient operation of oil wells by optimizing production operation parameters on the basis of not affecting production and not increasing input.
