【摘要】 近年来先后在普光、龙岗地区礁、滩体油气勘探中获得的重大发现,揭示开江—梁平海槽区礁、滩体具有良好的油气勘探前景。本文基于叠前偏移地震资料,结合钻、测井勘探成果数据,在沉积、构造分析的基础上,应用层拉平、体曲率、层序地层学解释及叠前反演等技术,在龙岗西区开展二叠系长兴组生物礁和三叠系飞仙关组鲕滩储层的预测和描述,取得了较好成效,并初步形成一套礁、滩体识别的系列技术及配套流程。更多还原

【Abstract】 The discoveries of reef-shoal reservoirs in the regions of Puguang and Longgang in recent years have shown a promising exploration future in the Kaijiang-Liangping trough area.Using prestack migration seismic data combined with drilling and logging information,identifications of bioherm in the Changxing formation and oolitic reservoir of the Feixianguan formation in western Longgang region have been successfully achieved by a series of technologies such as horizon-flattening,volume-curvature,sequence stratigraphy,and prestack inversion.An assorted preliminary workflow for reef-shoal body identification is developed and may contribute an important reference for similar areas.更多还原
