Abstract

Изобретение относится к нефтедобычи и информационным технологиям в нефтедобыче и касается методов управления режимом периодической откачки нефти из малодебитных скважин. Сущность изобретения заключается в способе управления периодическим режимом работы малодебитных нефтяных скважин. Способ состоит в определении снижения уровня жидкости в затрубном пространстве до приема насоса. Способ осуществляется путем анализа сигнала, полученного с датчика усилий, и сравнения его информативных признаков с эталонными. Если значения информативных признаков текущего сигнала равны или превышают значения эталонных, то принимают решение об остановке работы насоса по достижению необходимого уровня жидкости на приеме насоса. В качестве информативных признаков сигнала усилий используют длительность позиционно-бинарных составляющих (ПБС) сигнала, формируемых в процессе его аналого-цифрового преобразования. Для сравнения текущего и эталонного сигналов определяют числовую оценку близости по изменению длительностей ПБС сигналов с учетом веса их позиций. Таким образом, при наличии в базе данных 5 образцовых и 4 распознаваемых сигналов распознавание сигналов, соответствующих определенному уровню незаполнения на входе насоса, производится с высокой надежностью, и вследствие этого устраняются случаи ложного переключения режимов.The invention relates to oil production and information technology in oil production and relates to methods for controlling the periodic pumping of oil from low-production wells. The essence of the invention lies in a method for controlling the periodic mode of operation of low-production oil wells. The method consists in determining a decrease in the level of fluid in the annulus prior to receiving the pump. The method is carried out by analyzing the signal received from the force sensor, and comparing its informative features with the reference ones. If the values of the informative features of the current signal are equal to or exceed the values of the reference ones, then they decide to stop the pump after reaching the required fluid level at the pump intake. The duration of positional binary components (PBS) of a signal formed during its analog-to-digital conversion is used as informative signs of a stress signal. To compare the current and reference signals, a numerical estimate of the proximity is determined by changing the duration of the PBS signals taking into account the weight of their positions. Thus, if there are 5 exemplary and 4 recognizable signals in the database, the recognition of signals corresponding to a certain level of non-filling at the pump inlet is made with high reliability, and as a result, cases of false mode switching are eliminated.
