鄂尔多斯盆地安塞油田坪桥区属特低渗透油田，自然产能低，需人工压裂后投产，开发好这类油田难度极大。采用国内外先进技术手段，建立了具有人工裂缝和不稳定钙质夹层的三维地质模型，并充分体现于油藏数值模拟模型中，同时考虑了人工裂缝对注气开发的影响和注气的风险性，比较符合实际；油藏数值模拟使用全组分模型，对不同开发方式进行了分析研究和对比，对油田实际开发具有指导作用。
Pingqiao District, Ansai Oilfield, Ordos Basin is a very low permeability oilfield with low natural productivity and need to be put into operation after artificial fracturing. It is extremely difficult to develop such fields. Using advanced technology at home and abroad, a three-dimensional geological model with artificial fractures and unstable calcareous interbeds has been established and fully embodied in the reservoir numerical simulation model. At the same time, the influence of artificial fractures on gas injection development and the risk of gas injection Which is more in line with the actual situation. The reservoir numerical simulation uses the all-component model to analyze and compare different development modes, which can guide the actual development of the oilfield.
