摘要:

近年来在塔里木盆地台盆区顺南—古城地区中—下奥陶统(6 000~7 200m)、塔中中深井区中—下寒武统(6 400~7 000m)及麦盖提斜坡罗斯2井奥陶系蓬莱坝组(5 800m)深层相继获得天然气发现,气源对比显示天然气主要来源于寒武系。台盆区深层天然气干燥系数(C1/C1-4)基本>0.95,以干气为主;天然气甲烷碳同位素值(δ13C1)主要分布在-39.0‰~-33.5‰之间,部分<-40.0‰;乙烷碳同位素值(δ13C2)在-39.0‰~-32.0‰之间,与干酪根热模拟实验结果吻合较好,相当于玉尔吐斯组烃源岩在20℃/h升温速率热模拟条件下550~600℃产物。中深1井∈2a及中深5井∈1w受寒武系干酪根裂解气晚期充注影响较小,热演化程度相对较低,以低成熟度原油伴生气为主。台盆区海西期以来寒武系过成熟干酪根裂解气对深层油气藏的持续充注,是造成目前台盆区深层天然气干燥系数偏高及碳同位素组成偏重的主要原因。不同地区深层天然气藏受储层物性、构造断裂活动及寒武系过成熟干酪根裂解气差异充注影响,导致不同层段天然气性质差异较大。

Abstract:

In recent years,many natural gas reservoirs have been discovered in the platform-basin region of the Tarim Basin.For example,Shunnan-Gucheng area in the Middle-Lower Ordovician (6 000-7 200m),Tazhong area in the Middle-Lower Cambrian (6 400-7 000m) and Markit Slope Well LS2 in Ordovician Penglaiba Formation (5  800m),the natural gas is mainly from the Cambrian source rocks by the results of gas-source correlation.In the platform-basin region,the dryness coefficient of natural gas (C1/C1-4) was mainly greater than 0.95 and it is defined as dry gas;the isotopic value of methane (δ13C1) was mainly distributed from -39.0‰ to -33.5‰,partly less than -40.0‰;while the isotopic values of ethane (δ13C2) are distributed from -39.0‰ to -32.0‰,which was in accordance with the results of kerogen thermal simulation experiments at 550℃ to 600℃(at 20℃/h).With little influence from the charging of Cambrian kerogen pyrolysis gas and low degree of thermal evolution,the interval of Well ZS1 ∈2a and Well ZS5 ∈1wcontain low maturity of oil associated gas.The impact of the charging of post-mature kerogen pyrolysis gas from Cambrian source rock,led to the deep natural gas with the characteristics of high dryness coefficient and heavy carbon isotope values.The characteristics of deep natural gas in different areas of Tarim Basin vary greatly,the main reasons include physical properties of reservoirs,tectonic fault activity,and differential filling of Cambrian over-mature kerogen pyrolysis gas.

Key words: Tarim Basin, Deep natural gas, Geochemical characteristics, Thermal simulation, Accumulation process
