【 摘 要 】

As the main seepage channel of carbonate reservoirs, the spatial distribution and the development range of the fractures are crucial for the deployment of the measures wells in the carbonate oil fields. Taking the high water cut fracture reservoir of R oilfield as an example, the advanced fracture prediction technology is used to predict the development and distribution characteristics of medium and large scale fractures, and the space of complex carbonate reservoirs is quantitatively characterized by fracture-porosity dual medium modeling technology. According to the distribution law, the dual medium numerical simulation technology is carried out to study the distribution characteristics of the remaining oil in the oilfield, and the well selection scheme is determined by combining the geological factors and the development factors. Through the implementation of on-site measures, the wells have achieved good oil-increasing effects, which provides a guarantee for the cost reduction and efficiency of the oilfield.
