Application Of Logs And Seismic For Describing Channel Sand Body To Gaotaizi Oil-bearing Reservoirs In Sazhong Area

In Sazhong development area of North East a zone broken Gaotaizi after30years of waterflooding， the block plane high water film distribution，In Sazhongdevelopment area of North East a zone broken Gaotaizi after30years ofwaterflooding， the block plane high water film distribution，Water flooding further"control water，decreasing is more and more difficult to control.".。At the same time，despite the development of long-term， but still there are a large number of remainingoil in this block of sand body， In order to tap the remaining oil， we timelyapplication of combination of well and seismic channel sand body description， finedescription of the narrow channel sand bodies of underwater distributary gaotaizi，We conduct Gaotaizi water fine description of the narrow channel sand bodydistributary， through the perforation， fracturing， increase the intensity ofgovernance inefficient wells， These Gaotaizi reservoir forming fine matchingtechnology， increasing reserves and oil increase， provides a feasible approach.In recent years， block to carry out fine adjustment of district. Through theinjection wells and production wells tapping the potential of the fine adjustment ofgovernance， to achieve the effective control of production decline， water cutincrease. Fine program in reservoir description basis， the study area of Gaotaizireservoir characteristics， reserves distribution， now well producing potential ofremaining oil were analyzed， We conduct fine potential tapping technology based onsubdivision water injection， comprehensive use of various adjustment measures，ensure the development of small injection into the water， pouring enough water，water injection well， Improvement of control degree of water flooding and the sweptvolume， so that more than three times and thickness ratio reached50%， up to70%to80%in three years， the water in the oil and the natural decline significantlycontrol， Three years of containing water rise respectively control in0.23%，0.20%and0.18%，3.48%，3.30%，3.10%in control of natural decline， improve waterflooding development effect.
