【摘要】：为了对南美洲谱图马约—奥连特—马拉农(简称POM)盆地油气资源潜力开展重新评价,基于最新的地震、测井和油气藏储量等数据,在盆地成藏要素综合分析基础上,以储集层为核心划分出9套成藏组合。以成藏组合为核心,采用主观概率法和规模序列法预测9套成藏组合内待发现油气可采资源量11.0×10~8 t,其中Hollin组砂岩、Napo组T段砂岩、Napo组U段砂岩和Napo组M1段砂岩4套成藏组合内待发现可采资源量(10.4×10~8 t)占全盆地待发现可采资源量的94%。在烃源岩、储集层、圈闭、运移、盖层和保存等成藏要素评价的基础上,应用资源-地质风险概率双因素法评价出4个Ⅰ类成藏组合、2个Ⅱ类成藏组合、3个Ⅲ类成藏组合。应用成藏组合范围叠合法优选出盆地中部为最有利勘探区。
[Abstract]:In order to reevaluate the potential of oil and gas resources in the Mayo-Orent-Malanoun Basin (POM) basin, a spectral map of South America, based on the latest data of earthquakes, logging and oil and gas reservoir reserves, and on the basis of comprehensive analysis of the reservoir forming elements in the basin, Taking the reservoir as the core, 9 sets of reservoir forming assemblages are divided. Taking the accumulation assemblage as the core, The subjective probability method and scale sequence method are used to predict the recoverable oil and gas resources in 9 sets of reservoir formation assemblages. The recoverable oil and gas resources are 11.0 脳 10 8 t in 9 sets of reservoir formation assemblages. Among them, 4 sets of oil and gas recoverable resources can be found in 4 sets of reservoir formation assemblages of Hollin sandstones, T member sandstones and Napo M1 member sandstones. The amount of resources mined is 10.4 脳 10 ~ (8 t), which accounts for 94% of the recoverable resources to be discovered in the whole basin. Based on the evaluation of hydrocarbon source rock, reservoir, trap, migration, caprock and preservation, four types 鈪，
