Embodiment Construction

[0038] see Figure 1 ~ Figure 3 , an ART2-based identification method for the indicator diagram of the pumping unit, (the identification process is as follows figure 1 shown,) includes the following steps:

[0039] Step 1: Draw the theoretical dynamometer diagram of the pumping unit (theoretical dynamometer diagram is as follows figure 2 shown), to obtain a sample of the indicator diagram of the pumping unit;

[0040] Step 2: Carry out data preprocessing to the sample of the pumping unit indicator diagram obtained in step 1;

[0041] Step 3: Carry out feature extraction to the sample of the pumping unit dynamometer diagram through data preprocessing in step 2;

[0042] Step 4: If the number of categories of the sample of the pumping unit indicator diagram obtained in step 1 is known, first use a set of known categories as the training set to train the ART2 neural network, establish a discriminant model, and then use the establishment The model of the pumping unit is used to...

Abstract

The invention discloses a pumping unit indicator diagram identification method based on an ART2. By collecting load and suspension center displacement signals of a pumping unit, a closed curve formed along with time changes in a pumping period is drawn with polished rod displacement signals serving as an x-coordinate and loading signals serving as a y-coordinate, and a pumping unit indicator diagram sample is obtained. If the category of the pumping unit indicator diagram sample is known, the pumping unit indicator diagram sample is identified through a mode with a supervision module. If the sample category of the pumping unit indicator diagram sample is unknown in advance, the pumping unit indicator diagram sample is identified through a mode without the supervision module. The pumping unit indicator diagram sample is identified through an ART2 neural network, according to an identification result, fault diagnosis and underground work condition judgment are performed on the pumping unit, and a judgment result is displayed. The pumping unit indicator diagram identification method based on the ART2 has the advantages of performing fault diagnosis and underground work condition judgment on the pumping unit, identifying the indicator diagram stably, efficiently and accurately, and the like.

Description

technical field [0001] The invention relates to an energy-saving method for a pumping unit, in particular to a recognition method for an indicator diagram of a pumping unit based on ART2 (Adaptive resonance theory, adaptive resonance theory). Background technique [0002] With the continuous advancement of science and technology, the requirements for oilfield exploitation are getting higher and higher. "Digital oilfield" is no longer a slogan, but has become a reality. Oilfields increasingly need automatic oil measurement technology with high degree of automation and strong real-time performance. Traditional oil measuring technologies (such as metering station oil measuring, tipping bucket oil measuring, glass tube oil measuring) have problems such as complicated process flow, many devices, high investment cost, high labor intensity and low efficiency, and it is difficult to adapt to simplify the ground process. Production management needs for continuous calculation of outp...
