摘　　要：为了提高地震资料的分辨率、保真度和成像精度，并增强解释精度，满足岩性油气藏精细勘探需要，通过对海拉尔盆地岩性地震勘探方法研究，形成以宽方位角观测系统设计的“四高（高接收道数，高覆盖次数，高时间采样率，高空间采样率）、四精确（精确测量，精确表层调查，精确吸收衰减分析，精确激发井深设计）、三小（小面元，小组合距，小滚动距）、二中（中频检波器，中药量）、一宽（宽方位角观测）、三措施（震检联合组合，实时现场质量监控，实时动态环境干扰监控）”岩性勘探地震采集方法，保真处理及精确成像、复杂断陷盆地层序地层学解释、精确储层预测、岩性圈闭识别描述等技术为核心的岩性地震勘探配套技术系列，在海拉尔盆地地震勘探中应用取得了突出的地质效果。随着勘探难度加大，需进一步加强基底裂缝储层、南一段砂体地震识别预测、复杂油藏含油气性地震预测方法攻关。The auxiliary technology series of lithologic seismic exploration, presenting an obvious effect in seismic exploration in Hailaer Basin, is formed through the research on lithologic seismic exploration method for Hailaer Basin, in order to improve seismic resolution, fidelity, and imaging and interpretation accuracy to meet the requirement of fine exploration for lithologic hydrocarbon reservoir. The key technologies include lithologic seismic acquisition method following the principles of ＂four high, four accurate, three small, two medium, one wide, three measures＂ based on the wide azimuth observation system, fidelity processing and accurate imaging, sequence stratigraphy interpretation of complex rifted basin, accurate reservoir prediction, lithologic trap identification and description etc. With the increasing difficulty of exploration, the research efforts should be strengthened on the seismic identification and prediction of basement fractured reservoir including sand body in Nan Member Ⅰ , and the seismic prediction method for hydrocarbon in complex reservoir.
