Research on Full Length Fracture Simulation and Reservoir Reforming in Block Z89
As China's continental oil fields enter the mid to late stages of development,the difficulty of development gradually increases,such as high water content and declining recovery rate.Further developing the remaining oil is a key issue in improving the production capacity of oil reservoirs,and the key measures to solve the problem include refined dissection of development units,layered injection and production,acidification,sealing,fracturing and other reservoir transformation measures.Based on the mechanical parameter model between wells,numerical simulation is conducted on the three-dimensional full fracture length of artificial fractures during fracturing,and optimization research is conducted on the matching between fractures and well network,as well as the three-dimensional spatial morphology of artificial fractures.A more effective driving system is established to maximize the effective swept volume.On the basis of numerical simulation,the well pattern,sand body,artificial fractures,and oil-water well relationship are considered uniformly.Different types of reservoirs are transformed in different scales to achieve the optimal development effect of reservoir transformation technology,achieving effective development of low permeability reservoirs.
