摘要
分析了抽油过程中油层给出能量的变化规律，认为用补偿装置不可能减少油层能量消耗。深入讨论了吸入方式和吸入能量的问题，指出补偿装置的吸入方式和普通抽油泵并无本质差别；普通抽油泵吸入消耗的能量并非由动液面提供，而是由抽油设备本身所提供；动液面提供的只是沉没压力，补偿装置同样需要。最后分析了补偿装置的有关试验资料，认为试验结果并没有说明其原理的正确。
After analyzing the pattern of the variation of the energy supplied by oil reservoir in the course of oil pumping,the author thinks that the energy loss of the reservoir cannot be reduced by using the energy compensating device presented in Reference 1.The author conducts a further investigation in the suction mode and the energy sucked,and indicates that there is no essential difference between the suction modes of the compensating device and the sucker ac pump; the energy consumed on the suction stroke of the pump is not provided by the dynamic fluid surface, but by the pumping equipment itself; the dynamic fluid surface provides only submersible pressure,which the compensating device also needs.Analyzing the test data of the compensating device,the author thinks the test result didn' t prove the principle of the device comet.
