王家岗东部地区位于济阳坳陷东营凹陷南斜坡的东段,该区构造、沉积特征复杂。目前钻探井位相对较少,地质认识不够深入。近期利用波形分类、频谱分解等方法,对王家岗东部地区沙四段滩坝砂岩储层展布特征和成藏主控因素进行研究,取得了新的认识,在此基础上进行的勘探工作取得了良好的效果。 The eastern part of Wangjiagang is located in the eastern slope of the southern slope of the Dongying Sag in the Jiyang Depression, where the structural and sedimentary characteristics are complex. At present, there are relatively few drilling wells and the geological understanding is not deep enough. Recently, by using the methods of waveform classification and spectral decomposition, the distribution characteristics of sandstone reservoirs and the main controlling factors of hydrocarbon accumulation in the sandbodies of Es4 in the east of Wangjiagang have been studied and new understandings have been obtained. The exploration work based on this Good effect.
