摘　　要：川东北宣汉-达县地区以构造圈闭为主要勘探对象,钻探成功率低,为此开展了以储层预测技术为主导的构造-岩性复合圈闭勘探。通过山区地震数据高分辨率采集、处理、储层沉积相研究、储层测井响应特征、储层物性特征及储层层位标定、地震相研究、储层地震预测方法研究,确立了研究区内的三大储层类型及各类储层的研究方法,提出了川东北复杂储层预测以野外地震资料高分辨率采集为基础、多种特殊处理手段相结合,并以沉积相研究为指导的综合性研究思路,为川东北宣汉-达县地区储层预测方法研究提供了指导性意见,为该地区复杂储层勘探的深入与突破打了坚实的基础。Structural trap is the main exploration aim in the Xuanhan--Daxian area of the northeast of Sichuan Province, but the rate of success is very low. So, based on the reservoir prediction technique, the structural-lithologic complex trap exploration is gone into effect. By high resolution seismic collection and processing and reservoir sedimentary facies researching, combined with reservoir welllogging and horizon identification ,seismic facies analysis and reservoir seismic prediction technique in mountainous area, three kinds of reservoir and their relative research ways have been identified. Besides that, the authors have provided guidance opinions for the reservoir prediction technique study and pointed out that the integrated way should be based on high resolution seismic collection and several special processing methods and under the guidance of the sedimentary facies studying in this areas. Finally, aceording to this reservoir prediction technique, a prominence exploration effectiveness has made.
