断盖配置垂向封油气所需的最小断距预测方法及其应用
|
摘要
为方便地判断断盖配置是否垂向封闭油气,在断裂破坏泥岩盖层封闭机理及其与断距关系研究的基础上,通过确定断裂停止活动时期、泥岩盖层厚度、压实成岩时间和下伏储层岩石泥质体积分数,建立了断盖配置垂向封油气所需最小断距预测方法。以渤海湾盆地南堡凹陷南堡5号构造F3断裂为例,利用钻井和地震等资料得到F3断裂在9条测线处断距,结果表明:南堡5号构造F3断裂与东二段泥岩盖层配置垂向封油气所需最小断距在不同测线处存在差别,在测线L1、L4、L6、L8和L9处F3断裂断距小于其与东二段泥岩盖层配置垂向封油气所需最小断距,断盖配置垂向封闭,有利于油气在其下聚集与保存;而在测线L2、L3、L5和L7处F3断裂断距大于其与东二段泥岩盖层配置垂向封油气所需最小断距,断盖配置垂向不封闭,不利于油气在其下聚集与保存。研究结果与南堡5号构造F3断裂附近东二段泥岩盖层之下油气分布相吻合,证明该方法用于预测断盖配置垂向封油气所需最小断距可行。
In order to conveniently judge whether the fault-caprock configuration can vertically seal the oil and gas or not,on the bases of the sealing mechanism of the mudstone cap damaged by the fracture and its relationship study with the fault throw, the predicting method of the minimal fault throw required for the vertical sealing of the oil and gas by the fault-caprock configuration was established by determining the stop period of the fault activities, thickness of the mudstone caprock, compaction diagenesis time and shale mass fraction of the underlying reservoir rock. Taking Fault F3 in Nanpu Structure-5 of Bohai Bay Basin as an example, with the help of the drilling, seismic and the other data, the fault throws in nine measuring lines were obtained in Fault F3. The results show that there exits difference between Fault F3 in Nanpu Structure-5 and the minimal fault throw required for the vertical oil-gas sealing by Member Ed2 mudstone caprock configuration in different measured lines. The fault throws of Fault F3 in L1, L4, L6, L8 and L9 are less than the minimal fault throws required for the vertical sealing of oil and gas by Member Ed2 mudstone caprock configuration, and the vertical sealing by the fault-caprock configuration is favorable for the accumulation and preservation of the oil and gas. However, in L2, L3, L5 and L7, Fault F3 throws are on the contrary and moreover are not favorable for the accumulation and preservation of the underlying oil and gas. The study results are coincident with the oil and gas distribution under the Member Ed2 mudstone caprock near Fault F3 in Nanpu Structure-5, and furthermore the method is feasible to be applied in predicting the minimal fault throw required for the vertical sealing of the oil and gas by the fault-caprock configuration.
