综合地震解释技术在松辽盆地南部大面积薄层岩性油藏预测中的应用

松辽盆地南部是我国主要的油气生产基地之一，属于典型的大面积、低丰度油气田类型，具有圈闭幅度低、断裂发育、储层薄的特点，在油气藏类型上以构造圈闭及大量的构造岩性复合油气藏为主，油藏复杂、多变。经过多年的科研攻关，在技术上积累了一套有针对性的处理、解释方法。生产实践证明，这套建立在三维地震基础上的以真三维解释、小断裂检测和地震相控制下的高精度地震反演为代表的技术系列是实用有效的，具有推广价值。

Application of comprehensive seismic data interpretation in reservoir prediction in the south part of Songliao basin

The south part of Songliao basin is one of main producing bases in China. It is characterized by low-amplitude traps, rich fractures, and thin reservoirs, and is an oilfield typical of large area and low abundance. The reservoirs in this area are mainly structural traps and structure-lithological ones. They are varied and complicated. A suite of data processing and interpretation methods has been developed after intensive researches on key technical problems over years. These methods have a feature of 3-D seismic based true 3-D interpretation and minor fracture detection, as well as seismic fades constrained high-resolution inversion. The effectiveness of the methods has been verified in practice.
