济阳断陷盆地隐蔽油气藏勘探技术

The techniques applied for Jiyang fault basin subtle reservoir exploration

胜利探区济阳坳陷是我国陆相断陷盆地的典型代表。近年来,该坳陷勘探目标中复杂隐蔽油气藏所占比重日趋增大,勘探形势向勘探技术不断提出新的挑战。因此,不断发展、推广、应用隐蔽油气藏勘探新技术,进一步完善识别小砂体、小断块、古潜山等复杂隐蔽地质体油藏特征及流体性质已成为油田勘探工作者近期乃至今后相当一段时间致力研究的课题。本文概述了济阳坳陷该类油气藏勘探技术的发展历程,介绍了已初步形成的关键勘探技术系列,列举了典型隐蔽油气藏的成功勘探实例。

Jiyang Depression of Shengli exploration area is a typical continental fault basin of China. In the recent years, the complex subtle reservoir in proportion to the exploration targets in the depression is going up, the exploration situation constantly challenges the exploration techniques. The development, generalization and application of new techniques for the subtle reservoir exploration, and further improving the quality in identifying small sands, fault blocks, buried hills etc are the main task for explorers in the future, even over a long period of time. This paper generalizes the development of this kind of techniques, systematically discussed the key exploration techniques series those were shaping up initially, gave some successful examples in the subtle reservoirs exploration in Jiyang depression.
