广西田林地区构造演化及其对油气藏影响评价

广西南盘江坳陷发育有较成熟的烃源岩,显示出较好的成藏条件。田林地区位于南盘江坳陷的中部,依托页岩气基础地质调查井“田地1井”研究显示,田林地区有机碳含量、烃源岩干酪根均显示具有一定的生烃能力;田林地区断裂构造活动复杂、多期多阶段,自烃源岩开始生烃后,断裂活动异常频繁,对油气的运移、聚集及油气分布起到了非常严重的破坏作用,这是田林地区“田地1井”未见明显油气藏显示的重要因素。

Structural evolution and its impact assessment on oil and gas reservoirs in Guangxi tian Lin area

Abstract:The development of Nanpanjiang depression have mature source rocks, showing good reservoir conditions in Guangxi. The central area is located intermediate section in the Nanpan jiang depression, Relying on shale gas basic geological well "Tiandi 1#" research shows that, Organic carbon content and kerogen of source rocks all showed some hydrocarbon generation ability in Tianlin area. The fault structure in the Tianlin area is complex and multi-stage and multi-stage. After the hydrocarbon generation started from the hydrocarbon source rocks, the fault activities are extremely frequent and have a very serious disruptive effect on the migration and accumulation of oil and gas and the distribution of oil and gas, This is an important factor in the "Tiandi 1#" in the Tianlin area where no obvious oil and gas reservoir has been shown.
