城区地震勘探井炮安全距离探讨
|
摘要
在HSE要求日益提高的形势下,城区地震勘探所面临的问题已成为油气勘探不可回避的问题之一。城区炮点布设既要保证周围建筑物的安全,又要合理地布设炮点,尽量避免因浅层地震资料的大面积缺失而造成资料品质下降。目前施工人员获得的安全距离缺乏区域针对性,施工中无法有效平衡安全和质量的关系。从建筑物允许的振动安全速度入手,结合工区的实际资料探讨了对不同建筑物作业的安全距离及用药量,在实际应用中获得了较好的勘探效果。
Along with an increasing requirement to HSE, the problems faced by seismic exploration in urban areas become unavoidable. The shot-point layout in urban areas must not only ensure the safety of the surrounding buildings but also avoid data qualitydecrease due to shallow seismic data missing in large area. At present, the safe distance obtained by operators is short of regional pertiaence, which cannot effectively strike a balance between safety and quality. Starting with safe vibration velocity allowed for buildings,the safe distance and explosive amount for different buildings are discussed. Good exploration effects are achieved..
