摘要： 中国多旋回盆地超深层海相碳酸盐岩储层成因具有多因素联合控制与多阶段复合成因的总体特点。塔里木盆地阿满过渡带北部地区超深层奥陶系鹰山组、一间房组之上存在相对完整的上奥陶统、志留系，几期不整合没有叠加且暴露时间相对较短，储层发育受控于沿断裂发生的深循环岩溶作用，主要沿断裂带分布。阿满过渡带南部地区奥陶系超深层储层发育受控于走滑断裂活动强度、分段性及热液流体改造，分别形成了热液白云岩储层(古城墟隆起鹰山组下段)、热液流体交代形成的硅化岩储层(顺南斜坡区鹰山组上段)、热液流体改造形成的微生物岩储层(顺托顺南地区一间房组)。基于断裂流体主控型碳酸盐岩储层发育地质模式和针对性的地震采集、处理工作，通过叠前各向异性裂缝反演、多参数定量雕刻与叠后储层、裂缝预测技术及与应力场模拟的结合，可预测储层空间分布。

Abstract: The genesis of ultra-deep marine carbonate reservoirs in polycyclic basins in China is characterized by having multiple control factors and multistage hybrid origins. In the northern transitional zone between the Awati and Manjiaer depressions, the ultra-deep carbonate reservoirs of the Ordovician(in the Yingshan and Yijianfang Formations)are overlain by a relatively complete sequence of the Upper Ordovician and Silurian. Since there was no superimposition of multistage unconformities and the exposure period was relatively short, the reservoirs were formed by deep-circulation dissolution and distribute along the fault zones. The development of the ultra-deep Ordovician carbonate reservoirs in the southern transitional zone between the Awati and Manjiaer depressions is controlled by the strength and segmentation of strike-slip fault activity and hydrothermal fluid alteration. Hydrothermal alteration resulted in the formation of hydrothermal dolomite reservoir(in the lower Yingshan Formation in Guchengxu uplift), while hydrothermal metasomasis led to the silicified rock reservoir(in the upper Yingshan Formation in the Shunnan slope area). Hydrothermal alteration also led to the formation of microbial reservoir (in the Yijianfang Formation in the Shunnan to Shuntuo area). Reservoir distribution could be predicted by the geological model of fault-fluid dominated carbonate reservoirs, the specific seismic acquisition and processing, series of forward anisotropy fracture inversion, quantitative volume estimation, poststack seismic characterization, and simulation of tectonic stress field.

Key words: carbonate reservoir, ultra-deep sequence, reservoir genesis, reservoir prediction, transitional zone between the Awati and Manjiaer depressions, Tarim Basin
