摘　　要：长庆油田地势起伏不平,注水站和所辖注水井之间存在较大的海拔高度差,为了分析海拔高度差对油田注水地面系统效率的影响,首先提出了折算压力的计算方法;并根据注水站和注水井的相对位置,提出了几种类型注水系统,分别计算考虑海拔高度差和不考虑海拔高度差两种情况下的系统效率,分析由于海拔高度差导致的误差大小,同时为了简化测试、计算工作量,给出了忽略海拔高度差的条件。The terrain of Changqing Oilfield is undulating,and there is a large difference in altitude between the water injection station and the injection well under its jurisdiction.In order to analyze the effect of the altitude difference on the efficiency of the oilfield water injection surface system,the calculation method of converted pressure is first proposed;and according to the water injection Based on the relative position of the station and the water injection well,several types of water injection systems are proposed.The system efficiency is calculated under the two conditions of considering the altitude difference and not considering the altitude difference,and the error caused by the altitude difference is analyzed.At the same time,in order to simplify the test and calculate the workload,give the conditions to ignore the altitude difference.
