【摘要】 松辽盆地北部西坡地区勘探程度较低,地震资料以二维为主.为有效认识西坡地区的构造特点,满足勘探部署的要求,开展了二维地震资料连片的骨干线处理.借鉴大庆油田徐家围子地区的连片处理经验,形成了以模型约束静校正、两步法反褶积、子波整形、速度拼接为关键技术的连片处理流程,应用该流程完成了西坡地区十条骨干线的连片处理,成像效果明显,断点清晰,波组特征清楚,层间信息丰富.成像数据为西坡地区地质构造和资源潜力的认识提供了资料基础,所形成的连片处理方法可在同类地震地质条件的研究区推广应用.更多还原

【Abstract】 Exploration degree of the Western slope area of north in Songliao basin is low,and seismic data is primarily two-dimensional.In order to effectively understand the structural characteristics of western slope area,to meet the requriements of exploration deployment.we have launched a two-dimensional seismic data merging survey processing of backbone line.Learning from Daqing Oilfield Xujiawei area merging survey processing experience,we have summarized a model constraint statics,two-step deconvolution, wavelet shaping,velocity data merging as the key technology of merging survey processing. With this processing we have completed the western slope region merging survey processing of eight backbone line, obvious image result, clear breakpoints,wave group features clear,inter-layer information rich.Imaging data provide us data base for the western slope area of geological formation and resource potential.更多还原
