应用保真地震处理技术和层序地层学方法预测非构造圈闭

本文针对预测非构造圈闭这一油气勘探焦点问题,选择松辽盆地南部有利探区梨树断陷为研究区,采用保真地震处理技术对部分地震资料进行处理,首次应用层序地层学方法,综合地震、地质以及钻井资料,对区域沉积特征进行了剖析,将目的层划分为4个超层序和16个层序,确定了区域隐伏的湖底扇成因非构造圈闭,证明了保真地震处理技术与层序地层学方法的优越性和有效性。

APPLYING THE HIGH-FIDELITY TECHNIQUE AND SEQUENCE STRATIGRAPHY TO PREDICT NON-STRUCTURAL TRAP

In order to deal with the principal problem about prediction of non-structural traps in oil exploration, selecting Lishu fault-depression, a favorable exploration area in the south of Songliao Basin, as the studied area, where a part of the seismic data obtained in the area is processed using the highfidelity technique. Utilizing the sequence stratigraphy together with seismic, geologic and drilling data, the author analyzes the regional depositional features, divides the target bed into four super sequences and sixteen sequences, determines the non-structural traps formed by the regional hidden lake-floor fan. The result of the application mentioned above demonstrates the advantages and validity of the high-fidelity seismic processing technique and the sequence stratigraphy.
