| Huan jiang Oil Field8reservoir is located in huan county,gansu province.It’s one of themain production horizon. The study area has put into production,with the developingmining,there were many production problems were emerged,such as the water cut continued toincrease, the production rate has gone into a rapid decline phase,the development sitituationthere is becoming progressively worse,in the meantime,the difficulty of relying on the wholeadjustment of ild oilfield and enhancing oil recovery through conventional methods is greaterand greater.Under these circumstances,it is highly necessary to aim at maintaining thesustainable stabilization of oil production, set up reasonable development technology policyand put forward corresponding control measures with pertinence simultaneity.In this paper, on the basis ofapplication of regional geologic, conventional logging, testdata, reservoir monitoring data and a large amount of production material, we have made adetailed study on reservoir development characteristics and production declineregularity.During this process, this paper investigates reasons of rising water cut productionand predicted ultimate recovery of the reservoir.Then, Reservior engineering is used to studythe limits of reasonable development technology policy which is suitable for currentdevelopment. At last, on basis of reservoir research, development regular rule and the limits ofreasonable development technology policy reaserch, this paper rests on reservoir fluidmechanics, development geology and reservoir engineering theories with making an analogyto development experience of the same kind of reservoir at home,the effective and feasibleadjustment plan and scheme for dynamic surveying could be maded.The investigation results in this paper have practical guiding significance to chang8reservoir in xx area of Huan jiang Oil Field. All this is manifested in these aspects: improvingthe reservior development performance, maintaining the sustainable efficient development ofreservior and aming at stabilizing oil production and water control. |
