| 摘 要： | 泌阳凹陷梨树凹地区成藏条件复杂,主要的油藏类型为岩性油气藏和构造-岩性油气藏。岩性油气藏与微幅度构造油气藏规模小,识别和预测难度大。针对隐蔽小断层和微幅度构造,利用高精度三维地震资料,并结合测井资料,通过精细层位标定,采用综合解释技术,对古近系核桃园组目的层进行了精细解释;在此基础上,通过建立精细速度场,采用变速成图方法落实了微幅度构造。对比分析了由变速成图方法得到的结果和钻井结果,表明变速成图方法的绝对误差小,精度高。根据预测结果部署钻探的井在目的层段获得了一定的石油产量。

| Abstract: | The pooling conditions are complex in Lishuao area of Biyang Depression.There are lithologic reservoir and structural-lithologic reservoir at the area.Lithologic reservoir and micro-relief structural reservoir are small scale,which are difficult for identification.By using high-precision 3-D seismic data,combined with log data,aiming at subtle small faults and micro-relief structures,the target intervals of Paleogene Hetaoyuan formation were fine interpreted. On this basis,by building detailed velocity fiel... |
