桥口油田翼部发育低丰度复杂断块群,受构造、火成岩等因素影响,地震资料品质不高,且未进行过精细构造解释,存在断层空间展布规律不清、小断块刻画不精细等问题。通过综合分析测井、地质、生产动态资料,应用人机联作地震解释技术精细制作合成地震记录,并进行准确的层位标定,应用地层对比成果及高精度三维地震资料,利用过井任意线、相干体及水平切片相结合的立体解释方法,整体构造再认识。研究明确了桥口构造Ⅰ期断裂为黄河Ⅰ、Ⅱ号断层,Ⅱ期断裂为李屯及原黄河Ⅲ、Ⅳ断层,Ⅲ期断裂为玉皇庙断层,其中Ⅰ、Ⅱ号断层对构造和油气起重要控制作用;黄河Ⅲ号断层为桥口油田东翼北部的西边界控制断层,黄河Ⅳ号断层由北往东偏移;桥口油田西翼内部发育的次级断层由南向北存在构造转换,由北部西倾变为南部东倾;构造断层仍是桥口油田翼部油气富集的主控因素。 Due to the influence of tectonics and igneous rocks, the quality of seismic data is not high, and the interpretation of fine structure has not been carried out. There is an unclear distribution of the fault space and small fault blocks are not depicted Fine and other issues. By synthetically analyzing the well logging, geology and production dynamic data, the synthetic seismogram is finely produced by the man-machine cooperative seismic interpretation technology, and the accurate horizon calibration is carried out. By using the stratigraphic contrast and high-precision 3D seismic data, , Coherent and horizontal slice combination of three-dimensional interpretation of the overall structure re-understanding. It is clear that the first-stage faults in Qiaokou structure are faults Ⅰ and Ⅱ of the Yellow River, the second-stage fault is Li Tun and the former Huanghe Ⅲ and Ⅳ faults, and the third-stage fault is the Yuhuangmiao fault. The faults Nos. Ⅰ and Ⅱ of the fault structure and hydrocarbon Which plays an important controlling role. The fault of the Yellow River III is the western border control fault in the northern part of the east wing of Qiaokou oilfield, and the fault of the Yellow River Ⅳ migrates from north to east. The secondary fault developed in the west wing of Qiaokou oilfield extends from south to north. Conversion, from the north west dump into the southern east tilt; tectonic fault is still the main controlling factor of oil and gas accumulation in the wing of Qiaokou oilfield.
