摘要

松南地区八屋气田的储层有效厚度薄,一般为 2～3m,储层的横向变化大,且被多条断层切割,这种薄砂岩储层是否含气,如何识别,是长期以来地球物理学家们探索的难题。本文把测井资料与地震资料有机地结合起来,建立了“两步分离法”薄砂岩储层预测新技术及ACNL油气水识别新技术,有效地解决了困扰松南油气勘探开发的薄储层预测难题。

Abstract

The reservoirs in Bawu Gas Field in southern Songliao are typical of 2～3 meters thick with large lateral variations and are cut by several faulted.The gas bearing possibilities in such thin sandstonereser voir and its identification has bothered geophysicists for long time.By organically combining logging data and seismic data,this paper developed a two pass splitting method for thin sandstone prediction and a method called A CNL for oil gas water identification.
