塔里木盆地玉北地区构造特征及对奥陶系成藏输导体系的控制
|
摘要
玉北地区经历了加里东期-喜山期多旋回构造叠加影响,多期构造特征使得玉北地区断裂差异活动。除玉北1断裂后期叠加基底卷入断裂外,其余均以盖层滑脱断裂为主,中西部则以高角度基底卷入断裂为主,具有东早西晚、由东向西迁移的演化特征。多旋回演化导致寒武系盐下烃源岩多期生烃,玉北奥陶系油气赋存沥青、中-重质油及轻质油-天然气,中-重质油区含烃盐水包裹体PVTX的模拟等容线方程模拟出捕获时的温度、压力更为贴近实际,主成藏期为海西晚期、喜山期。主成藏期断裂控制油气输导体系较为复杂,主要为断裂型、不整合面、输导层型及其组合。区域盖层巴楚泥岩之下,NE、EW向基底卷入"穿盐"断裂及其控制输导层和不整合面叠置是油气垂向、侧向运移的关键,其构造脊线决定了油气优势运移的方向和路径,中西部NE、EW向"穿盐"断裂控制输导层及NE向构造脊等是晚期油气主要成藏单元。
The Yubei area, located in the Maigaiti slope, has undergone the Caledonian-Himalayan multi cycle structural superimposed influence, where the multi-stage tectonic features have led to the differential fault activities.The fault-fold zone in its east is mainly composed of cap detachment faults, except the Yubei 1 fault which has late basement involvement overlay. The middle west is mainly composed of high angle basement involved faults, which has the characteristics of east being earlier than west, and the characteristic of the westward migration.Multicycle evolution leads to multi-stage hydrocarbon generation of source rocks below layers of salt. The Ordovician oil and gas in Yubei area contains asphalt middle-heavy oil, light oil and natural gas.The simulation equation of PVTX of hydrocarbon bearing brine inclusions in medium heavy oil field is closer to reality, and simulates the temperature and pressure when it is trapped. The main reservoir forming period is Hercynian and Himalayan era. During the main accumulation stage, the fault control oil and gas transportation system is very complex, mainly composed of faults, unconformities, transporting layers and their combination. Under the regional Bachu mudstone cover,NE and EW trending faults basically involved in "salt pierced",superimposed the carrier beds under its control and unconformities are the key to vertical and lateral migration of oil and gas.The crestal line determines the direction and path of hydrocarbon migration,while the carrier beds are controlled by NE and EW "salt pierced" faults,and the NE trending tectonic ridges are the main reservoir forming units of late oil and gas.
