准噶尔盆地南缘山前带地震采集技术及成效

新疆准噶尔盆地南缘高探1井于白垩系清水河组测试获日产原油1213 m³/d、天然气32.17×10⁴m³,创整个盆地单井日产量最高纪录,充分证实了南缘油气勘探潜力巨大1]。为此,2019年,新疆油田在南缘共部署了875 km²三维地震采集项目,采用了井震联合采集技术、井炮源驱动技术、有线仪器+无线节点+有线连续采集技术、宽频单点接收技术、光纤表层调查技术等,高效、高质量完成了野外地震采集,地震资料品质得到了较好的提高,初步形成了适合南缘山前带的地震采集技术,为南缘山前带油气勘探和和下一步增储建产储备了相关的配套技术,该技术也可为国内其它探区山前带地震采集提供借鉴。

THE TECHNOLOGY AND DEVELOPMENT OF SEISMIC ACQUISITION IN SOUTHERN MAR?GIN OF JUNGGAR BASIN

Gaotan Well 1 has obtained 1213m³of oil and 321700m³of gas a day at the Cretaceous Qingshuihe Foration in the the southern margin of Junggar Basin.Gaotan Well 1 is the highest daily production of single well in the whole basin,which fully proves that the oil and gas exploration potential in the southern margin is huge.Therefore,a total of 875 square ki?lometers of three-dimensional seismic acquisition project was carried out in 2019.The field seismic acquisition has been com?pleted with high efficiency and high quality by adopting explosives and vibroseis,explosives source driving technology,wired instrument+wireless node+wired continuous acquisition technology,broadband single point receiving technology,optical fi?ber surface survey technology,etc.The quality of seismic data has been improved.The seismic acquisition technologies which are suitable for the piedmont of the southern margin have been preliminarily formed,and will promote the process of oil and gas exploration and increase reserves.These will provide reference for similar seismic acquisition in other piedmont areas.
