【摘要】 塔里木盆地桑塔木地区奥陶系潜山为裂缝-溶洞型储集层。2000-2001年采用三维地震采集-处理-解释一体化技术,加强了地表一致性、叠前去噪和保真处理力度,应用现代岩溶学理论、地震属性聚类分析、地震相技术,研究了桑塔木地区奥陶系潜山的构造特征、岩溶的空间展布规律,进而圈定出有利的储集层分布区。通过一系列配套技术的应用,精确描述了桑塔木地区奥陶系潜山顶面形态和特征,划分出了5条大的古水系和12个较大的岩溶高地,较客观地预测了潜山储集层的发育情况,计算了该区的油气探明储量。目前该区已建成年产20×104t的原油生产能力。更多还原

【Abstract】 The Ordovician buried hill in Sangtamu area of Tarim basin is a fractured and vuggy reservoir. In the year 2000-2001, the seismic data processing integrated with interpretation were made, intensifying the surface consistence, prestack noise elimination and Hi-Fi processing. By using modern karst theory, seismic attribute cluster analysis and seismic facies technique to study the structural feature and the karst special distribution in this Ordovician buried hill, the favorable reservoirs, the top configuration are well delineated, with objective prediction of development of the reservoirs and calculation of proved oil-gas reserves. Nowadays, the annual productivity of 200,000 tons has been constructed in this area.更多还原
