在研究影响石油中天然气溶解能力各种因素的基础上 ,分析了造成油溶相天然气释放的地质条件 ,讨论了油溶释放气成藏的特点。根据付晓泰等建立的油溶气量计算公式 ① ,建立了一套油溶释放气量的研究方法 ,并将其应用于松辽盆地北部喇麻甸气田的油溶释放气量研究。据此 ,齐家和三肇凹陷嫩一段油溶释放气量为 3.35× 10 8m3 ,约占该气田天然气地质储量的 6 .13% ,表明油溶释放气对该气藏的形成起到了重要作用
Based on the study of various factors that affect the dissolving ability of natural gas in petroleum, the geological conditions that cause the release of natural gas in oil-dissolved phase are analyzed, and the characteristics of hydrocarbon-dissolved release gas accumulation are discussed. According to the calculation formula of oil dissolved gas quantity established by Fu Xiaotai et al., A set of research methods of oil release gas release amount was established and applied to the study of oil released gas in Lamaadian gas field in northern Songliao Basin. Accordingly, the amount of gas released from the first phase of Qijia and Sanzhao Depression is 3.35 × 10 8 m 3, accounting for about 6.13% of the natural gas reserves of the gas field, indicating that oil-dissolved gas release plays an important role in the formation of the gas reservoir
