摘要
为了更客观、准确地反映地下地质情况 ,在地震资料解释中应做好地震和井资料的结合 ,尤其在已知油气区 ,这种结合显得更为重要。为此 ,本文认为应从以下几个方面做好这种结合 :地震层位精细标定 ,以钻井层位为主调整地震解释方案 ,发现、刻画隐蔽性断层 ,利用油藏关系寻找小断层 ,断层侧向封堵性的定性描述 ,充分利用地层倾角测井资料辅助构造解释 ,解释剖面中的特殊现象等。文中应用若干实例 ,对老区油藏勘探中较常见的几种震一井结合方式加以细述。解释实例表明 ,只有充分利用大量的钻井信息 ,并使其与地震资料最大限度地结合、互补 。
In order to more objectively and accurately reflect the underground geologic scenario,it must use combination of seismic data with drilling data to do seismic data interpretation,that is more important to known oil/gas region.Therefore,the paper considered that it must better make such combination in following aspects:seismic horizons being finely labeled;adjusting seismic interpretation schedule,discovering and describing the concealed faults mainly according to drilling-showed formation;using reservoir relation to find minor faults;qualitatively describing laterally plugging faults,fully using dipmeter synthetic curves to aide structural interpretation and interpret the special scenario on the sections.Some practical cases were listed in the paper in order to detailed description of common combination forms of seismic data with drilling data in reservoir exploration of maturing region.Interpreted cases showed the goal of fine structural interpretation can be achieved only by fully using abundant drilling information and making it maximum combination with seismic data.
