利用最新三维地震解释成果,结合钻井和区域地质资料,运用断裂生长指数、平衡地质剖面、趋势厚度恢复等多种方法对马北地区断裂组合、断裂发育期次、断裂演化、构造高点发育及迁移规律进行了精细解剖。依据断层组合关系、安德森断层模式及Harding1974年关于走滑断裂系应力、应变的相关论述,对该地区新生代以来各地质历史时期的应力状态进行了探讨,并以油气动态成藏的方式系统地研究了断裂-构造高点演化与油气藏之间的耦合关系,认为马北地区多期断裂是以马仙断裂为主导的走滑断裂体系,其断裂演化与马仙断裂活动息息相关,且与古今构造之间具有明显的耦合关系,两者共同控制了新生代油气藏的形成、改造及分布。
利用最新三維地震解釋成果,結閤鑽井和區域地質資料,運用斷裂生長指數、平衡地質剖麵、趨勢厚度恢複等多種方法對馬北地區斷裂組閤、斷裂髮育期次、斷裂縯化、構造高點髮育及遷移規律進行瞭精細解剖。依據斷層組閤關繫、安德森斷層模式及Harding1974年關于走滑斷裂繫應力、應變的相關論述,對該地區新生代以來各地質歷史時期的應力狀態進行瞭探討,併以油氣動態成藏的方式繫統地研究瞭斷裂-構造高點縯化與油氣藏之間的耦閤關繫,認為馬北地區多期斷裂是以馬仙斷裂為主導的走滑斷裂體繫,其斷裂縯化與馬仙斷裂活動息息相關,且與古今構造之間具有明顯的耦閤關繫,兩者共同控製瞭新生代油氣藏的形成、改造及分佈。

Based on the new interpretation on seismic data,integrated with drilling and regional geology,the paper dissected the fault assemblage,fault forming phases,fault evolution and the rule of structural high devel-opment by means of fault growth index,balanced section,and trend thickness method.According to fault as-semblage,Anderson fault mode and Harding's statements on stress and strain of strike-slip fault,stress condition since Cenozoic in Mabei area was discussed.Meanwhile,by adopting the dynamic approach,the coupling be-tween inchoate-nowadays geological structures and hydrocarbon reservoirs is studied.Multi-stage faults in Mabei area is the strike-slip fault system dominated by Maxian fault.The fault evolution in the study area is closely linked with Maxian fault.There was significant coupling relationship between the fracture and inchoate-nowa-days geological structures,and it is the fault and the inchoate-nowadays geological structures that jointly con-trolled the formation,reconstruction and distribution of Cenozoic hydrocarbon reservoirs.
