摘　　要：针对已有电火花震源产品地层分辨率和地层穿透深度不能兼顾的问题,提出了一种新的电火花震源技术——智能控制复合相干电火花震源系统.该震源系统包含六个组成部分,由嵌入式智能集成芯片实现智能控制.该系统在双震源模式下可以交替发射两种不同能量的地震信号,在一次探测中同时获得浅层的高分辨率地震资料和较深层的地震资料,提高勘探质量和效率;此外,该震源还可以相干激发,改善震源子波品质,提高震源的地层分辨率.To solve the problem that the existing sparker sources can not give attention to both stratum-detection depth and stratum resolution, this paper puts forward an intelligent controlled multiplex and interferential sparker source system. The system has six sections, and is intelligently controlled by a flushbonding microprocessor control unit. The source can shoot with different levels of energy alternatively. Using the source, the high-resolution seismic data of both shallow layers and deeper layers in one cruise can be achieved. Besides, the source can shoot interferentially to enhance the source wavelet quality.
