Pumping unit balance adjusting apparatus and pumping unit balance structure adjusting method

Abstract

The invention discloses a balance adjustment device for oil pumping machine and balanced structure adjustment method of oil pumping machine, by which the balanced structure adjustment is changed from using indirect parameter-electric current to using direct parameter-displacement, so that the adjustment is accurate and rapid, and the energy is remarkably saved. The invention also discloses an oil extraction control device, a color power indicator, an oil extraction measurement meter, an oil extraction integrated protection device, an oil extraction integrated testing and diagnosis control device, and a data acquisition and transmission unit for an oil extraction measurement and control system. The color power indicator provides a novel mean and method for diagnosis of oil pumping machine, which remarkably improves the effectiveness of diagnosis. The oil extraction integrated diagnosis control device and the data acquisition and transmission unit for the oil extraction measurement and control system have the advantages of high degree of automation, more monitored and controlled parameters, and large protection range; can perform onsite automatic acquisition and control and can perform long-distance automatic acquisition and control in management center; and provides a fundamental mean with high feasibility for realizing automated management of the full oil field.

Problems solved by technology

[0005] The disadvantages of the "balanced current method" are: 1. The "actually measured parameter" is the current, and the "actually adjusted parameter" is the displacement, which belongs to the "adjustment indirect parameter". The definite relationship between the displacement and the current cannot be given. , based on experience, make a rough estimate of the displacement of the balance block, and complete it step by step through multiple trial adjustments. 2. The theory and practice indicate that the “balanced current method” is adjusted very accurately, and the current balance is 100% achieved, which is not the most power-saving state (see for details, (4) on page 316 of "Petroleum Industry Energy Conservation Technology" —Petroleum Industry Press August 2000 first edition); 3, due to the above reasons, many beam pumping units in operation are not well balanced, thus wasting a large amount of electric energy

[0011] 1. The sensor is installed on the unstable moving object - the polished rod system. During the operation, the unstable flexible multi-dimensional vibration (caused by the flexible transmission part - the steel wire rope) is likely to cause damage to the instrument;

[0012] 2. The sensor is above the wellhead, which is a dangerous area. In the workover operation, if the instrument is not dismantled, it is easy to be collided by the dismantled and installed tubing and the running equipment, and it is also easy to be splashed by crude oil and high-pressure cleaning water. Contaminated, more likely to cause damage to the instrument;

[0013] 3. It can only form a single-color dynamometer diagram, and the information is not rich;

[0015] In addition, the data acquisition and transmission units of some oil production measurement and control systems have few functions and narrow application areas. People expect that one unit can monitor more parameters, so as to avoid the establishment of multiple measurement and control systems, resulting in repeated investment.
