摘要 太北开发区河道砂体发育规模小,钻遇率低,井网控制程度低,现井网条件下砂体预测精度低,断层认识精度低,单砂体注采关系不完善,开发效果差,开展井震结合精细油藏描述研究.井震结合构造认识成果表明:断层较以往认识结果相比变化较大,利用各类动静态资料分析断层的描述精度,认为井震结合断层描述精度高;井震结合微幅度构造描述更加精细,通过油水井的生产动态变化,研究微幅度构造对开发效果的影响;应用井震结合成果及多学科油藏研究成果,分析断层变化井区的剩余油,指导断层变化井区的补充井布井、注采系统调整及油田外扩调整,均取得较好效果. The developing scale of channel sand body in the Taibei Development Zone is small.The drilling rate is low.The well pattern control degree,the prediction accuracy of sand body under the condition of current well pattern and the accuracy of fault recognition is low.However the injection-production relationship of single sand body is not perfect,the development effect is poor.So the research of fine reservoir description by well-seismic integration method is carried out.The result of structural understanding by well-seismic integration method indicates: the fault has larger changes than the recognition result in the past,and after the analysis of the description precision of fault by use of various types of dynamic and static data,consider that the description precision of fault by well-seismic integration method is high;the description of micro amplitude structure by well-seismic integration method is becoming more elaborate,through production dynamic change of oil well,study the influence of micro amplitude structure on development effect;using the result of the well-seismic integration and multidisciplinary reservoir study,analyze the remaining oil in area which the fault changed,guide the adjustment of additional well,well spacing and the injection-production system and the adjustment of oil expansion,achieve good result.
