摘要：

以塔中古隆起下古生界碳酸盐岩典型油气藏解剖为基础,充分利用地球化学分析方法,明确寒武系是塔中海相碳酸盐岩成藏的主力烃源,塔中下古生界天然气主要为古油藏裂解气。塔中古隆起海相碳酸盐岩具有下生上储、多个储盖组合、多期成藏的复式油气成藏特征。并建立了塔中古隆起海相碳酸盐岩油气复式成藏模式,明确了礁滩复合体、岩溶不整合、内幕白云岩是塔中古隆起下古生界油气勘探的三大领域。

关键词: 碳酸盐岩, 复式成藏, 成藏模式, 塔中古隆起, 塔里木盆地

Abstract:

Based on the analysis of the typical oil and gas pools in the Lower Paleozoic carbonate rocks of the Tazhong Palaeouplift and by using geochemical analytical methods,that the Cambrian was the major source rock contributing to the marine carbonate reservoirs in Tazhong area and the natural gas in the Lower Paleozoic reservoirs was mainly cracked gases from fossil oil reservoirs were clarified.The marine carbonate reservoirs in the Tazhong palaeouplift was characterized by complex hydrocarbon accumulation features as generated in lower zones and preserved in upper zones,multiple reservoir-cap rock assemblages and multi-stage hydrocarbon accumulation.The complex hydrocarbon accumulation pattern was also established for the marine carbonate reservoirs in the Tazhong Palaeouplift,and three potential exploration targets,namely reef-bank complex,karst unconformity and inner dolomite,were nailed down in the Lower Paleozoic of the Tazhong palaeouplift.

Key words: carbonate rock, complex accumulation, hydrocarbon accumulation pattern, Tazhong Palaeouplift, Tarim Basin
