摘　　要：准确预测地层压力是盐间页岩油藏效益开发的关键,常规预测方法存在一定的误差。针对研究区地层异常高压与产油气特征,在盐间页岩油地层压力成因分析的基础上,数据驱动建立综合参数模型,提高了地层压力预测的准确性。通过多口实钻井验证,预测地层压力平均误差小,精度满足工程需求,为高效井位部署和安全钻井提供了依据。Accurate prediction of formation pressure is key to the efficient development of inter-salt shale oil reservoirs,but traditional methods have certain errors.Based on an analysis of abnormal formation pressures and oil-gas characteristics in the study area,a data-driven comprehensive parameter model was developed to improve pressure prediction accuracy.Verified through multiple drilling cases,the average prediction error was small,and the accuracy met engineering requirements,providing a basis for efficient well placement and safe drilling.
