[Abstract]:At present, the oil and water of 90% parts of the oil and water have been reduced with the drop of the liquid level and the depth of the lift pump has been expanded greatly when the oil production area has been greatly expanded, such as the oil layer with high yield, and the thin and differential oil layers have been transferred to the oil reservoir of the oil layer with the decreasing of the liquid level and the water rate at present. The influence of factors such as sucker rod pumping and other factors on the efficiency of the machine recovery system directly affects the development benefit of the whole oil by the research on the design of the deep sucker rod string with the key of the oil extraction mode of the oil pumping unit in the middle period of the oil extraction unit. The theoretical and practical significance of the theoretical and practical significance of the development of oil in the analysis of the load characteristics of the suspension point of beam pumping unit to determine the factors affecting the load of the suspension point through various kinds of rules. Calculation and comparison of parameters of conventional solid sucker rod string with thin-walled hollow sucker rod string structure and principle study on load reduction effect and load capacity of thin-walled hollow sucker rod string. Establishment of the mathematical model of load reducer, composite rod string and small straight pump for rational installation design the compound of the load reducer used for the theoretical shape of the sucker rod string is used to modify the calculation formula of the suspended point load and the minimum objective function of the maximum load of the suspension point for the theoretical shape of the sucker rod string. The Rod column Design method meets the pump depth of 4000m with Visual. Optimal Design Simulation Program for soft Phase of Basic Visual Program based on Theory comparison and calculation of Thin-walled Hollow sucker Rod string at 1000m pump the maximum load of suspension point can be reduced by 19.67% to 30.58% of crank. Net moment peak drop 11.3m / 21.95% balance peak moment drop 28.577.03% optimum design method for deep sucker rod column shows that pump 3000m with 蠁 28 蠁 38 pump suspended. The maximum point load is only 49.897 KN. 60.013 KN range loss 0.635m 1.283m pump 4000m with 蠁 28 蠁 38 pump the maximum load at suspension point is only 70.231kN. 82.162 KN process loss 1.191 m. The experimental data of 2.273m field and the theoretical calculation results of 6 oil show that the accuracy of the design method of deep sucker rod string combination for thin-walled hollow sucker rod string is verified by the coincidence of the theoretical calculation results of the theoretical load reduction of thin-walled hollow sucker rod string.
