特低渗透油藏注CO2驱油井网优化设计
摘要
Abstract
In terms of Daqing ultra-low permeability FY layers, which is difficult to develop effectively by water driving, combined with ShiilOl actual CO2-driving design, based on the parameter of miscible volume factor, sweep efficiency and oil draining rate, this paper applied gas-driven numerical simulation technology and oil reservoir method, researched intensively ultra-low permeability reservoir CO2-driven well patterns optimization design schedule and methods including well distance, well array spacing and well distribution plan. The result shows that in order to prevent gas breakthrough, the direction of well array should be consistent with the fracture direction; compared with the water injection, effective driving system can be built easily and the array distance can be increased; and single well production, sweep efficiency and oil draining rate of five point pattern are higher than the results of seven point pattern and nine point pattern, and the five point injection-production well pattern was used in the ShulOl block.关键词
