纯梁地区沙四段为典型的特低渗透薄互层油藏,需经压裂后投产。为了更好的指导压裂施工设计,根据纯梁地区的已知地应力大小和方向角,应用有限元方法,对整个区域进行二维有限元数值模拟,得到了该地区的地应力特征。
The Sha-4 Member in Chunliang area is a typical ultra-low permeability and thin interbed reservoir that needs to be put into operation after fracturing. In order to better guide the design of fracturing construction, the finite element method is used to simulate the whole area by two-dimensional finite element method based on the known geostress and azimuth of the beam. The geostress characteristics of the area are obtained.
