摘要:
针对安塞王窑区人工裂缝预测难度大、剩余油分布难以描述等问题，以安塞王窑区为研究对象，基于岩石破裂力学及应力模拟恢复理论，通过岩石力学、测井及地应力综合研究，建立该区人工裂缝三维定量预测模型。模拟研究表明，该区人工裂缝受水平最大主应力控制，人工裂缝的不对称分布造成近井地带剩余油动用不均，利用该技术指导单井剖面剩余油措施挖潜12井次，有效率100%，指导平面上部署加密井62口，初期日产能保持在2t以上。
Abstract:
In order to solve the problems in artificial fracture quantitative prediction and remaining oil distribution in Ansai Oilfield，the Wangyao area was taken as an example.On the basis of rock fracture mechanics and stress field recovery simulation theory，through comprehensively studying on rock mechanics，logging，and ground stress research，the three-dimensional artificial fracture prediction model was established.The simulation study showed that the artificial fracture distribution mainly was affected by the level maximum principal stress，and the asymmetric distribution of the artificial fractures was contributed to the uneven production of remaining oil near wellbore.This technique was used in oil wells to exploit the remaining oil for 12 times，with an efficiency of 100%.Sixty-tow infilling wells were drilled，and the initial production capacity was maintained above 2 tons every day.
