不同运移方向下断裂附近油气聚集的差异性
|
摘要
油气的运聚特征往往与断裂紧密相关。为了研究含油气盆地断裂发育区油气分布规律,在油气分布与对油气起输导或封闭作用断裂之间关系研究的基础上,利用不同油气藏之间类比、同油藏不同油层不同部位对比的方法,从油气运移方向的角度出发,研究断裂附近油气聚集的差异性。结果表明不同运移方向下断裂附近油气聚集的差异性主要表现为3个方面:油气运移方向受控于油气在断裂附近聚集的条件,油气侧向运移时油气聚集所需的条件是遮挡断裂侧向封闭,而垂向运移时油气聚集所需条件是受盖层阻挡;油气运移方向不同,油气在断裂附近聚集的层位不同,侧向运移时油气主要在盖层之下储层中聚集,而垂向运移时油气主要在盖层之下高砂地比储层中聚集;油气运移方向不同,油气在断裂附近聚集部位不同,侧向运移时油气主要在反向断裂下盘砂体中聚集,而垂向运移时油气主要在断裂上盘砂体中聚集。
There are close relationships between the petroleum migration-accumulation characteristics and faults.In order to study the hydrocarbon distribution laws in well-developed fault zones of the oil-gas basin,on the basis of the researches on the relationships between the hydrocarbon distribution and faults which transporting the oil and gas or playing the closure role,with the help of the methods of contrasting among the different hydrocarbon reservoirs and comparing among the different parts in the different oil layers in the same reservoir,from the viewpoint of the oil-gas migration direction,the differences are studied for the petroleum accumulation near the faults.The achievements indicate that the three main differences for different migration directions are shown as follows:the directions are controlled by the accumulation conditions for the oil and gas near the faults,the accumulation required condition for the lateral migration is the lateral closure of the barrel faults,on the contrary,for the vertical migration,the condition is the caprock barrel;for different migration directions,the accumulated layers near the faults are not same:for the lateral migration,the hydrocarbon is mainly accumulated beneath or below the caprocks,while for the vertical migration,the oil and gas are principally enriched the reservoirs with high sandstone-formationratio above and below the caprocks;for different migration directions,the accumulated parts of the petroleum are also different near the faults:for the lateral one,the oil and gas are generally accumulated in the sandbodies of the reverse-fault lower side;while for the vertical,the petroleum is mainly enriched in the upper-wall sandbodies of the faults.
