摘　　要：近年来,潜江凹陷蚌湖向斜深洼区陆续钻探的g79等一批井连续获得高产,通过研究,提出生烃(TSR)作用对油气高产富集具有显著控制作用:对砂岩储层物性具有明显改善;生烃超压形成的微裂缝形成油气的高效运移通道,二者耦合控制了深洼带岩性油藏的高产富集。A bunch of wells such as G79 drilled in the deep sag area of the Banghu syncline in Qianjiang depression have achieved high production in the consecutive years.Based on the study,it was suggested that hydrocarbon generation(TSR)has a significant control effect on oil and gas production and enrichment:it has significantly improved sandstone reservoir physical properties.The micro-fractures formed by hydrocarbon generation and over-pressure create efficient migration channels for oil and gas,and the coupling of both controls the high production and enrichment of lithologic reservoirs in deep sag zones.
