摘　　要：为了搞清齐家地区高台子油层油气成藏机理、油气分布规律及富集控藏因素,文章应用"相-势"耦合控藏理论,对齐家地区高三、高四油层组开展研究。研究结果表明:本区高三、高四油层组受相-势耦合控藏明显,根据计算得到的相势耦合指数与实际已勘探发现的油层井对比发现,高台子油层油层井分布在相势耦合指数FPI指数大于0.5的概率为88.4%,高三、高四油层组的相势耦合指数0.5<FPI<0.75分布区为潜在优质储层发育区。预测结果表明本区高三、高四油层组的潜在优势储层分布区为龙24-古932井区、龙124-古922井区,以发育油层为主。In order to analyze the hydrocarbon accumulation mechanism、the oil and gas accumulation and Enrichment control factors of Gaotaizi oil layer in qijia area,the paper applied the theory of"phase-potential"coupling control theory to carry out research on G3 and G4 oil layer.The results proved that The phase-potential coupling controling on hydrocarbon accumulation of G3 and G4 oil layer in this was obvious,According to the calculated phase potential coupling index,comparison with the oil flow well,it was found that the Phase potential coupling index of oil wells of Gaotaizi oil layer was Greater than 0.5,the probability was 88.4%.Distribution area of the Phase potential coupling index(0.5<FPI<0.75) of G3 and G4 oil layer were Potential high-quality reservoir development zone.Prediction results showed that Potential high-quality reservoir development zone of G3 and G4 oil layer were Long24-G932、Long124-G922,these places were mainly developed oil layer.
