【摘要】：北部湾盆地乌石凹陷为复杂断块油气藏,油气勘探开发过程中,面临钻井工程风险大、测井取资料作业困难等问题,如何精细描述井旁断层及裂缝等地质体的构造特征显得尤为重要。声波井旁地质体成像技术中偶极横波远探测测井技术,有效地提高了井旁地质体的描述精度。文中对井旁断层的成像特征及偶极横波的方位分辨率进行了正演模拟和分析,利用研究区2口井的声波测井资料验证了声波井旁地质体成像技术能够对井旁发育的小断层进行精确识别和描述。在油气勘探和评价阶段,该技术的应用能够优化钻井方案,避免工程风险,提高钻井效率,进而落实可采储量。
[Abstract]:The Wushi sag in Beibu Bay basin is a complex fault-block reservoir. In the process of oil and gas exploration and development, it is faced with many problems, such as the high risk of drilling engineering and the difficulty of logging data acquisition, etc.It is very important to describe the structural characteristics of geological bodies such as well-side faults and fractures.The dipole S-wave remote detection logging technique in the imaging technology of the geological bodies near the acoustic wells has effectively improved the description accuracy of the geological bodies nearby the wells.In this paper, the imaging characteristics and azimuth resolution of dipole shear waves are simulated and analyzed.Using the acoustic logging data of 2 wells in the study area, it is verified that the imaging technique of the geological bodies nearby the acoustic wells can accurately identify and describe the small faults developed by the wells.In the stage of oil and gas exploration and evaluation, the application of this technology can optimize drilling scheme, avoid engineering risk, improve drilling efficiency and realize recoverable reserves.
