塔里木盆地巴楚地区相继发现多个古生界油气田(藏)而成为塔里木盆地油气勘探的重要后备基地。本文主要通过较系统地论述区内寒武—奥陶系碳酸盐岩储集体特征和展布规律,指出了研究区寒武—奥陶系碳酸盐岩勘探应以内幕型非浅滩储层和古风化壳再造型储层为主,今后的勘探目标应是上寒武统和盐下白云岩大中型深层内幕圈闭和中—上奥陶统缺失区潜山型和改造型潜山圈闭。
A number of Paleozoic oil and gas fields (reservoirs) have been discovered in the Bachu area of the Tarim Basin in recent years and become important reserve bases for oil and gas exploration in the Tarim Basin. This paper mainly discusses systematically the characteristics and distribution of Cambrian-Ordovician carbonate reservoirs in the area, and points out that the Cambrian-Ordovician carbonate exploration in the study area should be based on the inside- And ancient weathered shell remodeling reservoirs, the future exploration targets should be buried in the Upper Cambrian and salt dolomite large and medium-sized deep inside traps and the Mid-Upper Ordovician missing area buried hill and the transformation of buried hill circle close.
