摘　　要：随着东部老油田油气勘探程度的不断提升,后续复杂地质目标的勘探对地震资料的分辨率和成像精度提出了更高要求,导致地震采集方案日趋强化,野外采集作业投入的设备数量急剧增加,地震勘探面临巨大的成本压力.面对东部老油区人口稠密、地表障碍密集的特点,无线节点具有放样不受地物制约、自主连续接收、采集排列可室内灵活定义的优势;与可控震源高效激发技术相配套,可实现复杂地表区三维地震采集的高效作业,从而缩短地震采集工期,缓解地震勘探成本的压力.2020年东方地球物理公司辽河物探处在辽河坳陷SJP地区的三维勘探表明,无线节点采集技术在复杂地表区适用可行,可以有效提高复杂地质目标的成像精度,是东部老油区地震勘探技术经济一体化的发展方向.With the continuous improvement of oil and gas exploration in the old oilfield in the east, the subsequent exploration of complex geological targets puts forward higher requirements for the resolution and imaging accuracy of seismic data, which leads to the strengthening of seismic acquisition schemes, the sharp increase of the number of equipment invested in field acquisition operations, and the huge cost pressure of seismic exploration. Facing the characteristics of dense population and dense surface obstacles in the old oil region in the east, wireless nodes have the advantages of not being restricted by ground objects, autonomous and continuous reception, and arrangement can be flexibly defined indoors, combined with vibroseis excitation technology, it can realize the efficient operation of 3 D seismic acquisition in complex surface areas, thereby shortening the seismic acquisition period and alleviating the pressure of seismic exploration costs. In 2020, the 3 D exploration in SJP area of Liaohe Depression by the Liaohe Geophysical Department shows that the wireless node acquisition technology is feasible in the complex areas, and improves the imaging accuracy of complex geological targets effectively, which is the development direction of the integration of seismic exploration technology and economy in the old oil in eastern regions.
