苏丹马鲁特(Melut)盆地位于苏丹3/7区勘探开发合同区内。该盆地具有典型的陆源碎屑断陷盆地的地质特征。2000年,中国石油公司获得该区块的勘探开发权,于2001-2003年间连续发现了Palogue、Moleeta、Gumry等构造油气田。但是随后几年,由于构造油气藏的勘探程度已经相当高,很难再发现有利的构造圈闭,导致勘探陷入了僵局。如何利用现代沉积学以及层序地层学理论来寻找岩性油气藏是下一步该区勘探的主要方向。
The Melut Basin in Sudan is located in the exploration and development contract area, Block 3/7, Sudan. The basin has the typical geological features of continental debris rift basins. In 2000, CNPC obtained exploration and development rights in the block and continuously discovered structural oil and gas fields such as Palogue, Moleeta and Gumry in 2001-2003. However, in the following years, due to the already high degree of exploration for structural reservoirs, favorable structural traps could hardly be found again, leading to a stalemate in exploration. How to use modern sedimentology and sequence stratigraphy theory to find lithologic reservoirs is the main direction of exploration in the next step.
