Study On Energy Saving And Consumption Reducing Of Crude Oil Gathering And Transporting System In Dongxin Oil Field

DongXin oil field has entered the especially high watery development period through more than 30 years development. The crude oil moisture content large scale rise, picks the fluid and the sewage process load sharp growth, the production energy consumption of collection and expulsion system also large scale to increase. The original craft, the equipment have not been able to adapt the production request, we must research the new technology, the new craft and so on, make the improvement to the production equipment and the craft, to meets the high watery time production need, reduces the production energy consumption diligently, raises the equipment utilization rate. In this article, Xin one station and Xin three stand for the pilot area, to mainly consumes energy the equipment, like the heating furnace, the oil water pump, the electrical machinery and so on carry on the efficiency test. To crude oil processing system, the oil transfer system as well as outside lose the pipe network and so on of the union station to carry on the energy analysis computation. According to the result of the test and computation, the energy consumption big in the crude oil collection and expulsion system is because of in the oil transfer system efficiency to be low, specially the feeding pump energy consumption and the pipe network pressure energy lost, as well as the heating furnace thermal efficiency was low. The potential to save the energy and reduces the consumption lie in enhances the feeding pump and the heating furnace operating efficiency, reduced the pipe network pressure energy loss. According to the question, it proposed the measure to save the energy and reduce the consumption. Through the improvement oil transfer technical process, uses the highly effective normal temperature to stick high bubbles the crude oil free moisture removing craft, the highly effective feeding pump frequency conversion velocity modulation technology, may enhance the oil transfer system efficiency. The reasonable control excess air coefficients may enhance the heating furnace the thermal efficiency. It may reduce the loss of heat to consume by the heat preservation to the sedimentation tank and the pipeline, so on. Through the contrast analysis discovery that the use energy conservation necessary technology can obtain the remarkable economic efficiency, it can save the energy expense to amount to 8,898,000 Yuan altogether every year.
