塔里木盆地为一多成藏系统盆地 ,同一含油气系统往往存在多个成藏系统。在克拉通区 ,轮南成藏系统实际上包括了 3个成藏子系统 ,即奥陶系常压开放型原生—次生油气藏成藏系统、石炭系超压半封闭型成藏系统以及三叠—侏罗系常压开放型次生油藏成藏系统。塔中成藏系统可分为中央断垒带原生—次生油气藏成藏系统和塔中北斜坡原生油气藏成藏系统 ,后者又包括奥陶系垂向运移成藏系统与石炭系侧向运移成藏系统。库车前陆油气系统可划分为北单斜带近源常压开放型成藏系统、中部前陆逆冲带近源—自源超压—常压封闭—开放型成藏系统以及轮台凸起近源—远源常压开放型成藏系统 3个成藏系统 The Tarim Basin is a multi-reservoir system basin. There are often multiple reservoir-forming systems in the same petroleum system. In the Craton area, the Lunnan reservoir-forming system actually consists of three reservoir-forming subsystems, that is, the Ordovician atmospheric-pressure open primary-secondary reservoir accumulation system, the Carboniferous overpressure semi-closed reservoir system, and Triassic-Jurassic open-pressure secondary reservoir formation system. The Tazhong gas accumulation system can be divided into the primary fault zone primary-secondary reservoir accumulation system and the Tazhong north slope primary reservoir accumulation system, which in turn includes the Ordovician vertical migration reservoir system and Carboniferous Lateral transport and accumulation system. The Kuqa foreland oil and gas system can be divided into the North single oblique zone near source and pressure open-type reservoir forming system, the central foreland thrust zone near source-self-source overpressure-normal pressure seal-open type reservoir forming system, From near source - far-source and open-pressure open-type reservoir forming system 3 accumulation system
