摘要： 在精细研究准噶尔盆地陆西地区露头、岩心、钻井、测井及三维地震等资料的基础上,对已知油气藏进行解剖,认为石南31井区下白垩统清水河组油气藏为重力流水道成因的岩性油气藏,并根据岩心、测井曲线和地震反射特征把清水河组底部的砾岩划分为底砾岩和滑塌砂砾岩,为该地区的非构造油气藏勘探开辟了一条道路。用实例介绍了利用地震属性确定含砂率拟合技术、三维可视化雕刻技术、储集层反演等技术如何识别非构造油气藏。所提出的寻找非构造油气藏的思路,适用于在“断坡、阶地、重力流”地质体中勘探非构造油气藏。

Abstract: This paper anatomizes the known reservoirs based on the researches on the outcrops, core samples, drilling, well logs and 3D seismic data, etc., proposes for the first time that the reservoir in Wellblock Shinan-31 is lithological reservoir coming from water channel of gravity current and distinguishes the conglomerate of the bottom of Qingshuihe formation (K1q1) into basal conglomerate and slip glutenite. The two kinds of conglomerates have identified from cores, well logs and seismic profile in this area. Also, this paper takes an example to illustrate the recognition of non-structural reservoirs in terms of combination of geological thought with the techniques of sandcontent matching, 3D visualization and reservoir inversion. Finally, this paper generalizes the thoughts for exploration of non-structural reservoirs in this area by ways of fault ramp, terrace land and gravity current.

Key words: gentle slope depression, lake basin, gravity current water channel, bottom glutenite, 3D visualization, reservoir inversion
