摘　　要：自20世纪80年代中期以来,石油工业广泛使用地质、测井、地震数据多学科综合方法对储层进行描述,取得重大进展。近年来,利用地震勘探技术解决开发问题成为研究的热点,但许多正在使用的方法未经严格论证,因此,开展开发地震技术基础研究十分必要。提出了几个重要课题:①介质不均质尺度;②地质地球物理模型;③地震数据对层序体的分辨能力;④储层目标地震信号的频率选择;⑤开发地震高分辨率技术;⑥高分辨率地震解释思路;⑦储层表征与描述的局限性。探讨了开发地震技术研究尺度与分辨率的关系。讨论了储层目标的检测与拾取方法的基础。The industry of petroleum have got along with using comprehensive methods of geologic, log, seismic data todescribe reservoirs since the mid of the 1980's. In recent years, it has become a topic of general interest that using seis-mic exploration techniques to solve the problems in development. The methods being used have been strict-ly demonstrated, so it is very necessary to develop the basic research of production seismic techniques. Several impor-tant topics are presented in this paper: ①heterogeneous scale of medium, ②geologic-geophysical model, ③resolutionof seismic data to sequence bodies, ④selecting the frequency of seismic signal to target, ⑤high resolution of exploita-tion seismic, ⑥The train of thought of high resolution seismic interpretation, ⑦limitation of reservoir characterizationand description. The relations between resolution and research scale of exploitation seismic techniques are discussed.The basic methods of detection and pick to target are also discussed.
