摘　　要：物质平衡法通过测试环空中的气体排量折算出真实的环空液面 ,可以克服双频道回声仪所遇到的困难 ,为分析泵效、折算地层压力及区块注水补充地层能量提供依据。中原油田采油二厂研制的拟液面测试仪既能用于有泡沫段的油井 ,又可用于无泡沫段的油井 ,对于井深超过 2 5 0In this paper,the real annulus liquid level can be obtained by the material balance method used to reduce the gas displacement in the annulus.Meanwhile difficulties of the double channel acoustic well sounder encountered are overcame.The foundation for analyzing pump efficiency,reducing formation pressure and injecting water in blocks to supplement the formation energy can also be offered.The pseudo liquid level survey instrument,manufactured by the second oil production factory of Zhongyuan oilfield,used to pump wells with or without foam slugs.It is more suitable for the well with depth exceed 2000 meters.
