作为岩性油气藏的主要类型之一,滩坝砂岩储层是发育广泛、勘探潜力巨大的一种储集体,是济阳坳陷勘探的重要方向。针对滩坝砂岩储层隐蔽性强、横向变化大、单层厚度薄的特点,开发了高精度古地貌恢复技术、学习型地震波形预测技术以及相控属性降维预测技术等系列特色预测技术,完成对不同类型滩坝砂岩的预测描述,形成了一套较为有效的滩坝砂岩储层描述技术序列,在东营南坡西段的勘探实践中发挥了重要作用,取得了显著的经济效益,推动了济阳坳陷其它地区滩坝砂岩油藏的勘探。

As one of main lithologic reservoir style, the beach bar sandstone is widely developed, with great exploration potential, being the most important exploration targets in Jiyang sag. In view of the sandstone reservoir characteristics of thin single interval, rapid lateral changing and subtle feature, a series of effective special beach bar sandstone prediction technology has been developed, such as high accuracy palaeogeomorphology buildup technology, learning type seismic wave form predicting technology ,and facies controlling attributes dimensionality reduction predicting technology, which play important roles in the exploration practices in west section of Dongying sag, acquiring obvious economic benefit, promoting the beach bar sandstone reservoir exploration in other areas of Jiyang depression.
