Based on three-dimensional seismic interpretation, structural and sedimentary feature analysis, and examination of fluid properties and production dynamics, the regularity and main controlling factors of hydrocarbon accumulation in the Tazhong uplift, Tarim Basin are investigated. The results show that the oil and gas in the Tazhong uplift has the characteristics of complex accumulation mainly controlled by faults, and more than 80% of the oil and gas reserves are enriched along fault zones. There are large thrust and strike-slip faults in the Tazhong uplift, and the coupling relationship between the formation and evolution of the faults and accumulation determine the difference in complex oil and gas accumulations. The active scale and stage of faults determine the fullness of the traps and the balance of the phase, that is, the blocking of the transport system, the insufficient filling of oil and gas, and the unsteady state of fluid accumulation are dependent on the faults. The multi-period tectonic sedimentary evolution controls the differences of trap conditions in the fault zones, and the multi-phase hydrocarbon migration and accumulation causes the differences of fluid distribution in the fault zones. The theory of differential oil and gas accumulation controlled by fault is the key to the overall evaluation, three-dimensional development and discovery of new reserves in the Tazhong uplift.

基于三维地震解释，构造和沉积特征分析，以及流体性质和生产动力学的研究，研究了塔里木盆地塔中隆起地区油气成藏的规律和主要控制因素。结果表明，塔中隆起油气具有复杂的成藏特征，主要受断裂控制，沿断裂带富集了80％以上的油气。塔中隆起存在较大的逆冲断层和走滑断层，断层的形成与演化与成藏之间的耦合关系决定了复杂油气成藏的差异。故障的活动规模和阶段决定了陷阱的充满度和相位的平衡，即 运输系统的阻塞，油气的充填不足以及流体积聚的不稳定状态都取决于故障。多期构造沉积演化控制了断层带圈闭条件的差异，多相油气运聚引起了断层带流体分布的差异。由断层控制的差异油气成藏理论是塔中隆起总体评价，三维开发和发现新储量的关键。油气的多相运移和聚集导致断层带流体分布的差异。由断层控制的差异油气成藏理论是塔中隆起总体评价，三维开发和发现新储量的关键。油气的多相运移和聚集导致断层带流体分布的差异。由断层控制的差异油气成藏理论是塔中隆起总体评价，三维开发和发现新储量的关键。
