Study Of Production Stabilization Technology Of Jurassic Reservoir In Panguliang Area Of Jing’an Oil Field

At present, there are many problems on the development of yan9Jurassic reservoir in Panguliang ZJ4area of Jing’an Oil Field, such as the water cut continued to increase, the production rate has gone into a rapid decline phase, the development sitituation there is becoming progressively worse,in the meantime,the difficulty of relying on the whole adjustment of ild oilfield and enhancing oil recovery through conventional methods is greater and greater.Under these circumstances,it is highly necessary to aim at maintaining the sustainable stabilization of oil production, set up reasonable development technology policy and put forward corresponding control measures with pertinence simultaneity.In this paper, on the basis of application of regional geologic, conventional logging, test data, reservoir monitoring data and a large amount of production material, we have made a detailed study on reservoir development characteristics and production decline regularity.During this process, this paper investigates reasons of rising water cut production and predicted ultimate recovery of the reservoir.Then, Reservior engineering is used to study the limits of reasonable development technology policy which is suitable for current development and analyzed distribution characters of remaining oil.At last, on basis of reservoir research, development regular rule and the limits of reasonable development technology policy reaserch, this paper rests on reservoir fluid mechanics, development geology and reservoir engineering theories with making an analogy to development experience of the same kind of reservoir at home,the effective and feasible adjustment plan and scheme for dynamic surveying could be maded.The investigation results in this paper have practical guiding significance to yan9Jurassic reservoir in Panguliang ZJ4area of Jing’an Oil Field. All this is manifested in these aspects:improving the reservior development performance, maintaining the sustainable efficient development of reservior and aming at stabilizing oil production and water control.
