摘　　要：轮南油田注水开发多年,地层压力偏低,注水井压降试井资料受油压落零、液面下降影响,80%压降试井曲线形态发生“异变”,导致储层特征识别不清、资料解释困难,采用井下关井工艺可以从根本上消除这些影响。钢丝投捞式井下关井工艺在轮南油田首次推广应用两口井,均获得了高质量试井资料,与前期所测资料对比,双对数曲线井储时间短,早期特征全,径向流明显,可供解释的地层信息丰富。After years of water injection development in Lunnan Oilfield,the formation pressure is relatively low,which results in zero oil pressure drop and liquid level drop of the water injection well.80%of the pressure drop well test data is“abnormal”,the reservoir characteristics are not clearly identified,and the data interpretation is difficult.Downhole shut-in technology can fundamentally eliminate those bad effects.The wire transfer downhole shut-in technique has applied to two wells for the first time in Lunnan Oilfield,and high quality well test data has obtained.Compared with the data measured in the early stage,the log curve well has shorter storage time,more comprehensive early characteristics,obvious radial flow,and abundant formation information for interpretation.
