摘要:
为保障注水井合理安全注水，单井注水管理过程中需要对实际破裂压力进行预测，以确定注水井口限压。根据海上油田单井注水储层特征及控制条件，建立一种阶梯式流量测试评价方法，并确定其选井原则及施工注意事项。通过在井口注水过程中的记录，获取连续稳定的多级流量和压力数据，分析注入速率与井底压力两者曲线的变化关系，推算出不同目标井的地层破裂压力值。现场应用表明，该测试方法所预测的破裂压力与目标井理论剪切破裂压力值较为吻合，能简便快速实现单井实际注水破裂压力的推算，并针对性地设计小于破裂压力的合理注水压力。阶梯式流量测试评价方法对现场调整单井提压注水具有良好的指导作用。
Abstract:
To ensure the reasonable and safe injection of water injection wells, it is necessary to predict the actual fracture pressure in the process of single well water injection management, so as to determine the wellhead pressure limit of injectors. According to the reservoir characteristics and control conditions of single well injection in offshore oilfield, a stepped flow rate test evaluation method is established, and the well selection principle and construction precautions are determined. The continuous and stable multistage flow rate and pressure data are obtained by recording the process of water injection at the wellhead. The relationship between the curves of injection rate and bottom hole pressure is analyzed, and the formation fracture pressure values of different target wells are calculated. The field application shows that the fracture pressure predicted by the test method is in good agreement with the theoretical shear fracture pressure of the target well, which can easily and quickly calculate the actual injection fracture pressure of a single well, and design a reasonable water injection pressure less than the fracture pressure. The stepped flow test and evaluation method has a good guiding role in adjusting pressure and water injection of the single well.
