摘要
番禺-流花天然气区已经发现了一些工业气田和含气构造,但随着勘探的不断深入,易发现的构造圈闭越来越少,不得不把目标区转向了地层岩性圈闭油气藏。为了解决该问题,在该区采用了地震地质综合解释技术。以P35目标区为例,从精细解释及尖灭点确定、"亮点"含气性判别、速度研究及深度域成图、三维可视化及地质分析等方面对P35目标区进行了综合评价,取得了较好的效果。
A number of industrial gas fields and gas-bearing structures were found in Panyu-Liuhua natural gas area,but with the deepening of oil exploration,there were less and less easy-to-be-found structural traps.Therefore,the target had to be turned to the subtle traps.In order to solve the problem,a comprehensive seismic and geologic interpretation technique was used in the area.By taking Target P35 for example,a comprehensive evaluation of the target combined with 3D visualization and comprehensive analysis of multiple attributes is used.On the basis of that,the reservoir is analyzed and the depositional system is classified.And the reservoir formation is determined.The geological model of the target layer and its causes are also analyzed,good results are achieved.
