摘　　要：“十五”以来,塔里木盆地石油地质攻关研究取得了多项新进展,主要表现在: 1)发现库车前陆盆地既富气也富油; 2)克拉通区下古生界碳酸盐岩油气富集受储层控制,斜坡带富油; 3)哈得逊周缘东河砂岩具有形成大型地层油气藏的地质条件; 4 )塔中地区志留系发育岩性油气藏; 5)下白垩统克孜勒苏群是塔西南喀什凹陷北缘的主要目的层; 6 )塔东地区原油裂解气勘探潜力颇大。近期的勘探思路是:以温宿凸起及周缘为重点,加强预探;积极评价轮南奥陶系潜山、塔中多目的层和哈得逊周缘石炭系3个有利区;准备塔西南西部、塔北西部英买力和塔东及塔东南地区3个新领域。Recently, the study on petroleum geology in the Tarim Basin made a good progress, and some important contributions were as follows. 1) The Kuqa foreland basin was rich in both natural gas and oil. 2) The oil and gas in the Lower Paleozoic carbonate rocks in the cratonic areas were controlled by reservoirs, with oil enriching in clinoform belts. 3) The Donghe sandstones surrounding Hadeson possessed the geological conditions to form a large-scale stratigraphic oil-gas pool. 4) The lithologic oil-gas pool developed in the Silurian in central Tarim area. 5) The Kezilesu Group in age of Early Cretaceous was a main target layer in northern marginal area of the Kashi Depression, SW Tarim. 6) There was a large potential of the crude oil cracking gas in eastern Tarim. In the recent future, the oil-gas exploration should focus our attention on the following three aspects. 1) The predicted exploration in the Wensu Rise and its surrounding regions should carry out. 2) Three economic regions, namely, the Ordovician buried hills in Lunnan, the multiple target layers in central Tarim and the Carboniferous strata near Hadeson, should be evaluated actively. 3) The further geological survey in the west part of SW Tarim, the Yingmaili area in west part of northern Tarim and east-southeast Tarim should come to the agenda.
