【摘要】 肯尼亚安札裂谷盆地与苏丹穆格莱德裂谷盆地具有相似的地质条件,中石油已在穆格莱德裂谷盆地油气勘探中获得突破。地质条件类比之下,安札裂谷盆地也应有所发现。通过对肯尼亚曼德拉台盆和安札裂谷盆地形成演化和构造特征的分析,结合重、磁、地震及钻井资料进行综合评价,重点应用老地震资料重新寻找突破点。安札裂谷盆地下白垩统上段地震相与中国渤海湾盆地古近系沙河街组三段生油层地震相具有相似性,而古生界曼德拉台盆与塔里木台盆也具有近似的地震相,推测这2个盆地具有较好的烃源岩条件。因此,通过对老资料的综合分析与评价,可能在肯尼亚取得油气勘探的新突破。更多还原

【Abstract】 Anza rift basin in Kenya has similar geological character to Muglad rift basin in Sudan.CNPC has found larger oil field in Muglad rift basin,and China National Offshore Oil Corporation (CNOOC) wants to find larger field in Anza rift basin which is of similar ge-ological texture to Muglad basin,the purpose of this research herein.The data of gravity,magnetic,seismic,and drilling are used to evaluate the hydrocarbon potential of the basin,and the reprocessed existing seismic data are used to map and find out the break-through point of exploration.It is thought that Anza basin has hydrocarbon generation potential referred from the seismic facies of K12 in the basin that is similar to that of source rocks developed in 3rd member of Shahejie formation in Bohai Bay basin,and Men-dela interior basin is similar in Paleozoic seismic facies to that in Tarim basin,China.Therefore,new exploration breakthrough may be achieved based on the comprehensive evaluation on the reprocessed existing seismic data.更多还原
