从百色“残留型”盆地的石油地质特征看我国南方小盆地找油前景

本文对百色“残留型”盆地的石油地质特征进行了系统的论述。百色“残留型”盆地具有原始沉积盆地大、残留盆地小,生油岩成熟度高、门限深度小。油层埋藏浅和具高产地质条件等特点。盆地虽小但勘探领域广阔。在勘探程度较高的田东凹陷的五个构造区带。有多种油藏类型。含油面积叠合连片程度高。对百色残留盆地的剖析,对我国南方中新生代小盆地的油气勘探有一定的指导意义。

PROSPECTS FOR OIL IN SMALL BASIN IN SOUTHERNCHINA FROM PETRO-GEOLOGICAL FEATURES OF BAISE RESIDUAL BASIN

The Baise residual basin is characterized by the fact that it is an originally big sedimentary basin,and a small residual ones it's with high maturity source bcds,low thresheld depths shallowly buried reservoirs and prolific production in geological conditions,etc.Although the basin is small,it's exploration category is wide.There are various types of reservoirs in the five structural zones of the relatively explorated Tiandong Sag,and oil bearing areas are highly overlapped and connected.The study and analysis of the Baise residual basin gives a certain guids important to the oil and gas exploration in the small Mesozoic and Cenozoic basin in southern China.
