Adaptability evaluation of Jiyuan low-permeability oilfield well network spacing

At present,due to unreasonable low-permeability reservoir well network,some wells flood in the process of developing premature,and water injection invalidly cycle severely,it is difficult to establish an effective pressure displacement system. Therefore,the establishment of a reasonable well pattern and well row spacing is important to improve the level of development of low permeability reservoir. In the eighth reservoir of Jiyuan low-permeability oilfield,for example,through the numerical simulation of Luo 1,the suitable block well pattern was determined. According to the reservoir matrix permeability and fracture density,the appropriate well row spacing was determined.
