Abstract: According to the analysis of field geological investigation,reservoir behavior and static state,the reservoir structure model of buried hill was built in Renqiu.Based on these,applying finite element method,the numerical simulation for paleotectonic stress field and modern tectonic stress field of buried hill has been carried out in Renqiu,the quantitative prediction for fracture distribution of buried hill has been made.Through a lot of analysis of reservoir behavior,the result of fracture prediction was confirmed correctly.Furthermore,the remaining oil distribution controlled by fracture was predicted too,the suggestion for further development oil and gas was put forward.

Key words: Renqiu, buried hill reservoir, fracture prediction, numerical simulation, stress field

摘要： 根据野外地质模拟调查和油藏动态、静态资料分析,建立了任丘中元古界潜山油藏构造模型.在此基础上,应用有限元法,对任丘潜山古构造应力场和现今构造应力场进行了数值模拟,对潜山裂缝分布作了定量预测,并通过大量的动态资料分析,证实了裂缝预测结果是较为可靠的.此外还预测了受裂缝控制的有利剩余油分布区,对进一步的油气开发提出了井位部署建议.
