Abstract

Pumping unit is an important oil field exploration and production machinery and equipment, and the superior performance of the pumping unit is a key factor of the energy efficient oil exploration. Enter in the later stages of oil exploration, oil dropped in recent years, the volume and efficiency to reduce energy consumption increases, the single-well pumping unit can not meet the demand of energy efficient oil exploration. This article is enterprise project on the basis of cooperation with the Shengli Oilfield Company, for the low efficiency of oil extraction site, energy consumption, and the inconvenience to the single well to work independently of management issues, starting from the point of view of energy saving, new energy-saving multi-well pumping unit study specific content and the results are as follows: 1. configuration of the new energy-saving multi-well pumping unit is designed to adapt to the development trend of energy-saving pumping unit, to meet the cluster wells oil production technology needs, saving power consumption, oil production of high-performance cluster wells pumping unit structure principle put forward by a motor drag adjacent wells (4-8 wells), For this reason, the study of cluster wells pumping machine machine driven multi-well mechanical coordination and configuration methods roulette coaxial sprocket design with independent intellectual property cluster wells pumping unit driven change to the institution of the new configuration, coordination between the various wells, work efficiently, to achieve energy saving, crude oil yield and improving economic efficiency goals. Rod load analysis and computational studies of the pumping unit rod load characteristics and hanging point wire rope by state, reasonably easy load calculation formula is derived according to the different conditions, and find the rod load and stroke the intrinsic link between the number of red wells gradient, fluid viscosity, and other factors, summed up the principle of selecting parameters of the the rod load calculation conditions, convenient hanging point load calculation. Research rod load variation in the duty cycle of the pumping unit to seek ways to reduce the peak rod load, and provide a theoretical basis for all wells in the momentum and movement coordination design. Design calculations and performance of the new walking beam a machine eight wells pumping unit \size optimization parameter selection of the pumping unit conditions, the results found by the instance of the multi-well pumping unit is relatively single well can work independently an energy saving of about 25.8%, and discusses the various parameters (such as stroke, stroke, hole deviation. angle, fluid viscosity, etc.) of the pumping unit performance indicators, provides a direct way to reduce the peak motor power, energy saving. The Beam Roulette multi-well pumping unit configuration has a lot of innovation in the structure, is designed to broaden the idea of ??multi-well pumping unit configuration. 4 new beam-one machine four-well pumping unit design analysis and performance study of the configuration program Shengli Oilfield pleased to adopt ready to go into production programs, so a detailed analysis of the configuration and performance its motion dynamics, the determination of the working parameters, as well as energy-saving effect are detailed research and analysis through the calculation example of the type of a four-well pumping unit energy savings of nearly 30%, saving the motor reducer and other equipment the models mature technology, and easy to implement, the best options in the oil field. Analysis and performance study of the design of the new chain-of four wells pumping unit configuration on the new chain-type machine four wells pumping unit conducted a detailed analysis of the calculation and performance, precise analysis of the calculated chain-pumping The motion of the machine from the frame, a reasonable choice of the pumping unit parameters, provides the basis for the subsequent design calculations. Analysis by calculating the results found that the chain pumping unit hanging point mostly in uniform linear motion stage payload smooth small impact, but the torque curve the mechanical accumulation, and can not achieve the effect of offset and balanced, energy-saving effect is not obvious, then ruled out chain pumping unit development in the field of multi-well design superiority. 6 multi-well pumping unit fault conditions and solve the program discussed the multi-well pumping unit may malfunction, fault conditions possible for the walking beam \Remedy: plus counterweight and adjust the phase method. Research and analysis of two remedies and found their pros and cons, and the basis for the field of multi-well pumping unit.
