叠前反演坐标转换技术在惠州凹陷地层岩性圈闭评价中的应用
The application of pre-stack inversion coordinate transformation technology to lithological traps evaluation of Huizhou depression
摘要
Abstract
The exploration in Huizhou depression of the Pearl River Mouth Basin has reached a high level.As structural traps are almost drilled in the area,the study of lithological traps in the shallow and middle formation has gradually been the focus of the exploration.Three major conundrums encountered in the study of lithological traps:Firstly,whether the trap effectiveness of a single sand body could match the closed relationship between the stratigraphic overlap lines and the fault? Secondly,it is difficult to determine the trap size when the position of stratigraphic overlap lines is uncertainty.Thirdly,it is difficult to confirm the trap effectiveness when multiple sets of sand bodies are in serious superposition.Based on the twice 3D seismic exploration and processed data,problems encountered in the exploration of lithological traps in shallow and middle formations are successfully solved by applying the pre-stack inversion coordinate conversion technology.The proposed methods and techniques have been developed for oil field verification,and proven experience can be extended to applications.关键词
