摘　　要：低孔、低渗油藏在开发后期油井含水上升,导致单井产能下降,甚至造成部分井水淹,严重影响了油田开发。以往常规酸化及压裂措施,针对此类油藏实施效果欠佳,无法起到控水增油的作用,因此推动了针对此类油藏中高含水油井控水增油工艺技术的研究。分析了研究区不同类型单井的见水类型,识别了不同见水类型的储层地质特征。在试验室进行了控水增油改进剂的堵水效果试验,验证了该药剂的可靠性和稳定性。通过优化堵水措施工艺,如改变相渗的压裂技术手段,采用定向射孔压裂堵水和裂缝型见水堵水措施工艺,进行了现场试验。室内试验及现场试验研究结果表明:所选用的措施工艺,对于中高含水井能有效的起到控水增油的作用,为研究区今后的堵水措施提供良好的指导,也为类似低渗油田开发提供参考。In the later stage of the development of low porosity and low permeability reservoirs,the water cut of oil wells increases,which leads to the decline of single well productivity,even the partial well flooding,which seriously affects the development of oilfield.In the past,conventional acidizing and fracturing measures cannot play the role of controlling water and increasing oil for the implementation of this kind of reservoir.Therefore,the technology of controlling water and oil in the high water cut wells is promoted.The types of water in different types of wells in the study area are analyzed,and the geological characteristics of different types of reservoirs are identified.In the laboratory,the water plugging effect of water control oil additives was tested.The field test is carried through by optimization of water plugging technology,for example,changing the relative permeability of fracturing technology,and applying oriented perforation fracturing water plugging and fractured water breakthrough and water plugging technology.The results of laboratory and field tests show that the selected process measures play effective role of controlling water and increasing oil for medium high water〖FL(K2〗cut stage wells.The laboratory and field tests provide a good guide for the future water plugging measures in the study area,and provide reference for the development of similar low permeability oil fields.
