    摘要
  • 绥中30-3构造区油气勘探的主要目的层是古近系沙河街组二、三段,属近岸湖底扇相,其近岸湖底扇砂岩具有较好的成藏条件。针对断裂系统复杂和沉积相带变化快导致地层对比、储层预测难度大的特点,在精细井震标定、子波提取,构造解释基础上,建立初始波阻抗模型,运用Jason6.2软件进行约束稀疏脉冲拟波阻抗反演。在反演拟波阻抗数据体上,分别提取了沙二段3套砂体波阻抗平面分布图,预测绥中30-3构造中南部为有利目标区,并提出了井位建议,对油田的进一步勘探开发具有一定的指导意义。
    The 2nd and 3rd members of the Shahejie Formation of Paleogene are the major oil and gas exploration targets in the Suizhong 30-3 structure. They were formed in a nearshore subenvironment filled by lacustrine fan facies. The nearshore sublacustrine fan sandstone has good reservoir properties for oil accumulation. Viewing the great difficulties in cross-well stratigraphic correlation and reservoir prediction for a complex fault system with rapid facies changes as such, we established an initial wave impedance model, and carried out constrained sparse pulse quasi-wave impedance inversion, based on fine calibration of well-seismic, wavelet extraction and structural interpretation using the commercial software Jason6.2. Based on the inversion quasi-wave impedance data volume, plane distribution maps for the three sets of sand bodies in the 2nd member of the Shahejie Formation were extracted, one favorable target area in south-central of Suizhong 30-3 structure was predicted and well locations were recommend.
