3D Strata Overpressure Quantitative Study

Abstract

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 "Strata Pressure Integrative Evaluation System" 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.

Key words: overpressure, quantitative, seismic, logging, seismic attribute
