Optimization Of Developing Patterns And Test Scheme Design For Fuyu Oil Layer In Xingbei Oilfield

With increasing in exploration and demanding for petroleum resources, low-permeability reservoirs has become an important target of exploration and development in the future in China.Due to fracture developed and poor property in low-permeability oilfield, with the rapid rising of water cut of oil wells and presurre of injection wells, water channeling is serious and effective response for water fooding is uneven, the ratio of low production and effective wells is large, EOR is low.Effect of water flooding in low permeability oilfield is sensitive to development well patern.As a result, research on reasonable well pattern for low permeability oilfield can make oil reserves in low permeability oilfield develop faster, which is very important to sustain and stable development of the field.In this paper,for reservoir charcteristics of Fuyu layer,we complete well pattern,test program design.Firstly,we research on feature of fracture development for Fuyang layers in Daqing region and the course of well pattern evolution for low-permeability oilfield in china. We Analyse the reservoir characteristics of Fuyu oil layer in Xingbei oilfield,and study its non-darcy seepage flow characteristic and forecast production. Based on the recognition of all above,we can research the economic limit and technical limit of well pattern for low permeability oil layers, optimise the well pattern and design nine kinds rectangle well pattern.we use the modeling technology and numerical stimulation for the predicting effect of the designed well pattern and optimise a best well pattern by using the economic assessment technology.Finaly,select the optimal test area for program design.
