【摘要】 柴达木盆地英雄岭山地恶劣的地震地质条件使得该区地震勘探久攻不克,"五上五下"均未取得成功。2010年砂37井获得高产工业油气流推动了该地区新一轮的地震技术攻关。通过实施"宽线+震检联合压制噪声"的技术,使得地震资料品质获得大幅度提高。2011年在该区域又开展了山地高密度三维地震勘探技术攻关,通过多井组合激发提高有效波能量、多检波器组合压制噪声、高密度三维地震观测系统、综合静校正技术及多域联合信噪分离技术的实施,使三维地震资料品质有了新的突破。根据新资料开展滚动处理和解释,结合地面地质、钻井资料等,有效落实了英东一号构造,发现和落实了多个钻探目标,为该区域进一步的油气勘探开发工作奠定了坚实的资料基础。更多还原

【Abstract】 Seismic exploration has failed due to the extremely poor seismic geological conditions in Yingxiongling mountainous area. In 2010, high-yield industrial oil flow was obtained in Well Sha-37, promoting a new round of technology research in the area. The seismic data obtained using the broadened line and the hole-geophone joint array to suppress noise was improved a lot. In 2011, high-density 3D seismic exploration technology research was conducted in the area. The quality of 3D seismic data was enhanced a lot, based on using multi-well excitation to improve the effective wave energy, multi-detector array to suppress noise, high-density 3D seismic acquisition, integrative static corrections, and noise separation from signal in multi-domain during seismic processing. According to rolling processing and interpretation of high-density 3D seismic data, surface geological data and well data, No.1 Yingdong structure was effectively implemented as well as the multiple drilling targets were discovered and implemented, which laid a solid material foundation for further exploration and development of oil and gas in the area.更多还原
