【摘要】 当油气管道的穿越工程遇到卵石覆盖区、围堰采砂区,以及裂隙发育带等时,由于地区结构复杂,孔隙大的原因,将造成浅层地震勘探效果不佳。鉴于此,这里根据高密度电法原理,并从正演模拟出发,研究了高密度电法在卵石覆盖区、围堰采砂区及裂隙发育带进行工程勘察的可行性和效果,并将该方法应用于工程实例。结果表明:对于卵石覆盖区、围堰采砂区,以及裂隙发育带的工程地质条件,高密度电法在穿越工程中的勘探效果更好。更多还原

【Abstract】 The effect of shallow seismic exploration method is poor for the complex geological structure such as coverage region of grain,cofferdam sand pit or fracture zone which the oil and gas pipelines construction often encounters.In view of this,this paper studied the feasibility and effectiveness of high-density resistivity method in coverage region of grain,cofferdam sand pit or fracture zone based upon the forward simulation principles and through the forward simulation and engineering investigation application.The results show that the effectiveness of high-density resistivity method is better than shallow seismic exploration in those regions.更多还原
