“滚动构造”是在正断层的“逆牵引”作用下形成的一种特殊的褶皱构造。这种褶皱构造的形态与主断层的形态密切相关,并有一定的数学关系。通过物理或数学模拟可以得到它们之间的数学关系式。利用这些关系式可以近似计算出主断层或褶皱的形态。滚动褶皱构造内的次级构造,例如次级断层、褶皱轴面的产状等,可以反映褶皱所在地区的构造发育史、沉积史。重力滑动构造往往也伴有滚动褶皱构造,重力滑动面一般位于超压泥岩或盐岩、膏岩地层内,它们往往是良好的生油层或盖层。同生断层往往也与滚动褶皱构造相伴生。由于断层面上不同的地层受压实的程度不同,可以通过断面产状的变化预测地层孔隙的变化和岩性组合特征,进而帮助寻找有利的生、储油层系,因此通过滚动构造的这些特征,可以进一步研究许多地质问题,为油气勘探服务。
“Rolling structure ” is a special fold structure formed under the action of normal “reverse traction ”. This fold structure is closely related to the morphology of the main fault and has some mathematical relationship. Through the physical or mathematical simulation can get the mathematical relationship between them. Using these relationships, the shape of the main faults or folds can be approximated. The secondary structures in the rolling fold structure, such as the secondary fault and the appearance of the folded axial surface, can reflect the tectonic history and sedimentary history of the area where the fold is located. Gravitational sliding structures are often accompanied by rolling fold structures. Gravity sliding surfaces are generally located in overpressured mudstone or salt rock and gypsum strata, and they are often good oil or cap rocks. Synchronous faults are also often associated with rolling fold structures. Due to the different degrees of compaction of different strata on the fault plane, changes in formation porosity and lithologic assemblage characteristics can be predicted by the change of profile occurrences, which in turn helps to find favorable facies and reservoir systems. Therefore, by rolling these features , To further study many geological issues for oil and gas exploration services.
