缅甸Shwebo盆地西部隆起的形成与演化及对油气勘探的意义——以缅甸某勘探区块为例

摘要

中国海洋石油公司在缅甸Shwebo盆地拥有X2区块的勘探权益.意在分析Shwebo盆地隆起区的构造演化过程,从而在隆起区寻找有利的勘探目标.从区域地质研究入手,分析了板块运动对Shwebo盆地演化的影响,并结合构造解释成果阐述了西部隆起区的形成与演化过程;通过对钻井数据的综合分析,描述了Shwebo盆地内的有效生储盖组合;综合评价隆起区的有效圈闭,为中国海洋石油公司在该区块的下一步油气勘探提供了方向.%China National Offshore Oil Corporation has the exploration rights of X2 block in Shwebo basin,Myanmar.In order to better understand the favorable exploration target in the uplift area,the tectonic evolution of uplift zone in Shwebo basin is analyzed.Specifically,this paper analyzes the influence of plate motion on Shwebo basin development as the regional scale and illustrates the formation and evolution of west uplift region by combining with the structural interpretation results;the results present the effective source reservoir cap assemblage on the basis of a comprehensive analysis of drilled well data;and further provide the direction of the next oil and gas exploration for China National Offshore Oil Corporation.
