          摘要:
          塔里木油田大北克深地区由于超深井高温高压,在测试过程中地层出砂,严重影响了试油试采以及储层的评价。介绍了油气井产层出砂机理,认为深储层压实作用较强,岩石致密且稳定性较好,只有生产压差过大或采出速度较快时才会导致岩石发生剪切破坏或张性破坏而引起地层出砂。基于测井计算的岩石力学参数和地层压力及地层应力数据,建立了裸眼完井的临界生产压差计算模型、射孔完井的临界生产压差计算模型和基于岩石单轴抗压强度的临界生产压差计算模型。采用出砂指数法、临界生产压差法及灰色关联统计分析法等综合预测产层出砂情况。实现了利用测井资料快速准确地计算生产压差,用于出砂定量分析与确定最优完井方案,为采油防砂提供决策依据。
          Abstract:
          Dabeikeshen of Tarim oilfield is characterized with ultra deep wells, high temperature and high pressure. The sand production in the process of well testing in this area seriously influences the process of formation testing, pilot production and reservoir evaluation. Introduced is sand production mechanism in the pay zones. It is believed that the main reason for formation sand production in compact and stabilized deep reservoir should be overloaded differential pressure and faster production speed, which can lead to rock shear fractures or tension fractures. On the basis of rock mechanical parameters, reservoir pressure and ground stress calculated by well logging data, established are the critical production differential pressure computation models for barefoot well completion, perforation well completion and for that based on rock’s uniaxial compressive strength. Pay zone sand production condition is predicted by combining following methods: the sand index method, the critical production differential pressure method and the grey correlation statistical analysis method, and so on. The production differential pressure is calculated rapidly and accurately withlogging data. The study is helpful in quantitatively analyzing sand production and determining optimum well completion scheme, and provides foundation for reservoir sand control decision making.
