【摘要】 塔里木盆地塔北地区广泛发育碳酸盐岩缝洞型油气藏,但由于该区奥陶系碳酸盐岩储层埋藏深,储集空间以裂缝、孔洞和溶洞为主,因此勘探难度大。在该区实施的高精度三维地震勘探中,针对储层特点,通过波动方程正演,进行了以提高信噪比和分辨率为目的的观测系统量化设计;并根据裂缝、溶洞型储层解释需要,采用了较宽方位观测。通过以上技术的应用,取得了良好的勘探效果。更多还原

【Abstract】 Fracture-vuggy carbonate reservoirs are widely developed in the northern Tarim Basin.However due to their large burial depth,and the main reservoir space being fractures,cavities and caverns,so the exploration is difficult.Regarding the characteristics of this type reservoir,the geometry quantitative design aiming at raising signal to noise ratio and resolution was conducted through wave equation forward modeling,in order to meet the need of interpretation for fracture-vuggy reservoir,wide azimuth observation was used.By application of the technique in north Tarim Basin,excellent exploration results were achieved.更多还原
