【摘要】 地层压力预测对油气资源评价、含油气系统模拟、保护油气储层、保证钻井安全、提高钻探效率等都有重要意义。基于地震、测井相结合的方法,并以地震属性为核心,通过地震属性提取、优选和标定等工作流程,以及线性、BP和克里金插值等数学方法,完成了"地层压力综合评价系统",实现地层超压的三维定量计算。通过在华北油田某工区的初步应用,显示了较好的适应性和实用性。更多还原

【Abstract】 Strata pressure prediction is significant for oil and gas resources evaluating,petroleum system modeling,reservoir protecting,ensuring drilling safety,improving drilling efficiency and so on.Based on the seismic-well logging method,especially on seismic attributes,this paper accomplishes òStrata Pressure Integrative Evaluation Systemó by means of the work flow of seismic attribute extracting,refining and demarcating,etc.and mathematical methods of linearity,BP and Kriging interpolation,realizing three-dimensional quantitative calculation of strata overpressure.Its preparatory application at certain area in Huabei Oilfield shows better suitability and practicability.更多还原
