Maximum pressure of injection wells over faults in specific well patterns——by taking the well pattern of one injection and three production in Bohai S oilfield as an example

  • 摘要: 注水压力是海上注水开发的关键参数,根据断层特点确定合理的压力,对海上油田安全高效开发意义重大。为了分析渤海S油田断层附近注水井的安全性,基于势的叠加原理和边界的镜像反映原理,对封闭断层附近的一注三采注采井网,推导出注水井作用在断层处的压力分布式。通过渤海S油田的实际注水井压力计算,得到作用在断层处的最大压力为15.89 MPa,低于断层失稳压力,表明注水井目前是安全的。压力分布公式对研究断层附近注水井的安全性具有一定的推广价值。

     

    Abstract: Water injection pressure is one of the key parameters of offshore water injection development. It is of great significance for the safe and efficient development of offshore oilfields to determine the reasonable pressure according to the characteristics of faults. In order to analyze the safety of water injection wells near faults in Bohai S oilfield, based on the superposition principle of potential and the mirror reflection principle of boundary, the pressure distribution of water injection wells acting on faults is deduced for the injection-production well pattern of one injection and three production near the closed faults. Through the calculation of the actual water injection well pressure in Bohai S oilfield, it is proved that the well is safe at present, and the pressure distribution system has a certain popularization value for the study of the safety of water injection wells near faults.
