塔里木北部沙参2井钻获古生界高产油气流,具有重要的石油地质意义。首先,它打开了塔北台缘隆起带古生界海相碳酸盐岩含油气领域,指明了近期油气勘探战役会战的目标;第二是油气藏于中新生界不整合面之下,岩溶和裂缝发育的古侵蚀淋滤带之中,与古隆起轴部断裂系统相关,这对开阔该区找油找气的战术思路很有意义;此外,该井油气藏于5363米以下,产能十分雄厚,也有力地证明在塔里木这个低地温的“冷盆”深部,古生界 Archean 2 wells in Tarim Basin have high oil and gas flow in the Paleozoic and have important petroleum geological significance. First of all, it opened up the Paleozoic marine carbonate rocks in the uplift zone of Tabei, Tarim, indicating the objective of the recent battle of hydrocarbon exploration. The second is that under the unconformity of Mesozoic and Cenozoic reservoirs, karstification and In the ancient eroded leaching zone with fractures, which is related to the fracture system of the paleo-uplift shaft, which is of great significance to the tactics of finding oil and looking for gas in the open area; besides, the oil and gas well below 5363 meters has strong capacity , Also strongly proved that in Tarim, the low temperature of the “cold basin” deep, Paleozoic
