摘要
文章提出了沉积盆地中油气在运移过程中的聚集、散失规律及定量计算油气聚集量的理论模式,包括:①划分了汇聚流、发散流、平行流三种油气侧向运移型式;②确定出聚敛型、发散型和平行型三种供油气单元;③分解离散供油气单元的生油量和排油量,模拟每一离散点的油气运移规律及建立油气聚集量的计算模式,计算出勘探区的油气聚集量;④探讨了准噶尔盆地阜康凹陷和吉木萨尔凹陷的油气聚散规律。
This paper proposes some Theoretieal Models describing the accumulation or loss of oil or gas formed in a basin during their migration. 1)3 types of lateral migration of oil and gas are classified:convergent,para- llel and divergent. 2)3 types of unit of oil and gas supply are identified convergent,divergent and parallel. 3)Amount of oil and gas generated and supplied by a discretized unit of oil and gas supplied is proposed,the migration of oil and gas in each discretized unit and the accumulation of oil and gas is simulated to form a model for the estimation of the amount of oil and gas accumulation,and then the amount of oil and gas accumulated in the explorated region is estimated. The oil and gas accumulated in Fukang and Jimsar sags in Junggar basin are dealt according to the above model.
