中-晚中新世,中卢卡尼亚盆地以发育碳酸盐岩建隆为特征,碳酸盐岩建隆的生长主要受控于构造活动强度、古地貌、海平面变化及陆源碎屑物质的输入:1)中-晚中新世,盆地稳定的构造背景有利于碳酸盐岩建隆的生长;2)渐新世-早中新世,伸展、走滑作用形成的北东-南西向地堑、地垒构造控制了碳酸盐岩建隆的类型和分布;3)海平面周期性升降影响碳酸盐岩建隆生长的旋回性;4)中中新世晚期、晚中新世和上新世,由盆地南缘、东南方向输入的陆源碎屑物质,抑制了碳酸盐岩建隆的生长,并使得其储集物性出现平面上的差异。最后,分析了碳酸盐岩建隆的油气储盖组合特征及其内部油气聚集影响因素。
中-晚中新世,中盧卡尼亞盆地以髮育碳痠鹽巖建隆為特徵,碳痠鹽巖建隆的生長主要受控于構造活動彊度、古地貌、海平麵變化及陸源碎屑物質的輸入:1)中-晚中新世,盆地穩定的構造揹景有利于碳痠鹽巖建隆的生長;2)漸新世-早中新世,伸展、走滑作用形成的北東-南西嚮地塹、地壘構造控製瞭碳痠鹽巖建隆的類型和分佈;3)海平麵週期性升降影響碳痠鹽巖建隆生長的鏇迴性;4)中中新世晚期、晚中新世和上新世,由盆地南緣、東南方嚮輸入的陸源碎屑物質,抑製瞭碳痠鹽巖建隆的生長,併使得其儲集物性齣現平麵上的差異。最後,分析瞭碳痠鹽巖建隆的油氣儲蓋組閤特徵及其內部油氣聚集影響因素。

During the Middle-Late Miocene, the Central Luconia Basin was characterized by the extensive development of carbonate buildups. Tectonic activity strength, palaeogeomorphology, sea level alternation and the influx of terrestrial material dominated the development of carbonate buildups. 1) The basin remained stable throughout the Middle-Late Miocene, thereby facilitating carbonate deposition. 2) From Oligocene to the Early Miocene, due to extensional and strike-slip tectonics, it was formed in this area the NE-SW trending graben and horst which dominated the type and distribution of carbonate buildups. 3) The cycle of carbonate buildup growth was related to the cycle change of sea level. 4) From the late stage of the Middle Miocene to Pliocene, terrestrial materials migrated from the south and southeast of the basin, suppressed the growth of carbonate buildups, resulting in the plane difference of reservoir physical property. Finally, the reservoir-cap combination features and the controlling factors for petroleum accumulation in carbonate buildups were analyzed.
