摘要:
塔里木油田大北克深地區由于超深井高溫高壓,在測試過程中地層出砂,嚴重影響了試油試采以及儲層的評價。介紹了油氣井產層出砂機理,認為深儲層壓實作用較強,巖石致密且穩定性較好,只有生產壓差過大或采出速度較快時才會導致巖石發生剪切破壞或張性破壞而引起地層出砂。基于測井計算的巖石力學參數和地層壓力及地層應力數據,建立了裸眼完井的臨界生產壓差計算模型、射孔完井的臨界生產壓差計算模型和基于巖石單軸抗壓強度的臨界生產壓差計算模型。采用出砂指數法、臨界生產壓差法及灰色關聯統計分析法等綜合預測產層出砂情況。實現了利用測井資料快速準確地計算生產壓差,用于出砂定量分析與確定最優完井方案,為采油防砂提供決策依據。
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.
