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。
針對安塞王窯區人工裂縫預測難度大、剩餘油分佈難以描述等問題,以安塞王窯區為研究對象,基于巖石破裂力學及應力模擬恢複理論,通過巖石力學、測井及地應力綜閤研究,建立該區人工裂縫三維定量預測模型。模擬研究錶明,該區人工裂縫受水平最大主應力控製,人工裂縫的不對稱分佈造成近井地帶剩餘油動用不均,利用該技術指導單井剖麵剩餘油措施挖潛12井次,有效率100%,指導平麵上部署加密井62口,初期日產能保持在2t 以上。

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 - di-mensional artificial fracture prediction model was established. The simulation study showed that the artificial fracture distri-bution 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 ca-pacity was maintained above 2 tons every day.
