巴拉那盆地是一个巨大的椭圆形盆地，覆盖巴西南部和阿根廷，巴拉圭和乌拉圭的部分地区，面积超过1，700，000平方公里（图1）。巴拉那盆地的油气勘探一直是一个挑战，因为世界上第二大的近岸泛滥玄武岩复合体覆盖在古生代沉积岩上（图1），而古生代沉积岩又被成群的闪长岩脉和岩床广泛侵入，使地震成像成为一项艰巨的任务。该盆地本身约占巴西陆上盆地沉积岩体积的一半，但仍未得到充分勘探。到目前为止，还没有发现石油或天然气的重大发现。
Parana Basin is a huge oval-shaped basin covering the southern portion of Brazil and parts of Argentina, Paraguay, and Uruguay, with an area of more than 1,700,000 km2 (Figure 1). Hydrocarbon exploration in Parana Basin has been a challenge due to the world's second-most-extensive inshore flood basalt complex overlying the Paleozoic sedimentary rocks (Figure 1), which in turn are extensively intruded by swarms of diabase dikes and sills, making seismic imaging a difficult task. The basin itself represents approximately one-half of the sedimentary rock volume of onshore Brazilian basins and is still underexplored. No major discovery for oil or gas has been made to date.
