为了扩大塔河油田主体，在塔河外围建立一个新的建产阵地，对于奇西三维地震资料进行精细解释，应用振幅变化率技术、精细相干体技术、趋势面分析、模型正演等技术，深入研究该区储层发育模式，盖层条件及储盖组合，精确描述油气藏成藏机制。并通过分析塔河主体已发现岩溶圈闭的测井、地震资料的地球物理响应，总结发现地震“串珠状”反射、岩溶“残丘高”为油气成藏有利区带。据此，在塔河于奇西地区识别描述了三级圈闭18个，合计面积298.3km2。
In order to establish a new oilfield in Tahe, we interpreted the 3D seismic data of Yuqixi area. We also applied amplitude change rate technology, fine coherence technology, trend surface analysis, and forward modeling techniques to research the reservoir development model, cover conditions and reservoir-cap combination in the area. As a result, an accurate description of hydrocarbon accumulation mechanism was concluded. By analyzing karst traps logging data and geophysical data, we summarized the favorable condition of the accumulation. Accordingly, we identified 18 traps in this area with the total area of 298.3km2.

受关键构造变革期制约，叠合盆地具有分期差异变形特征。从变形角度分析，塔里木盆地可以追溯出5期主要的构造改造作用，即加里东中期、加里东晚期海西早期、海西晚期、印支燕山期和喜马拉雅期，并影响塔里木盆地的发展演化历史。通过对塔北、塔中和库车已知油气聚集区解剖表明：古生代多期改造形成的断裂、褶皱、隆升、剥蚀和岩溶作用，对台盆区巨型海相碳酸盐岩古岩溶油气藏的形成具有重要的控制作用；中、新生代多期改造过程，对前陆褶皱冲断带大规模油气聚集成藏具有重要的控制作用；这些已知油气聚集区带都是在喜马拉雅晚期最终定型的，总体构成多期改造晚期定型复合构造油气聚集模式。综合分析了塔里木新区分期差异构造变形特征，在此基础上，依据叠合盆地多期改造晚期定型构造模式，对塔里木新区进行了区块评价和油气战略选区，认为巴楚隆起、麦盖提斜坡和西昆仑山前褶皱冲断带是近期油气勘探突破的首选地区，塔东地区、塘古巴斯坳陷和阿瓦提断陷具有良好的油气勘探前景。

基于二维地震剖面的精细地质解释,并结合钻井资料的分析,提出了塔北地区古生代以来草湖凹陷形成演化的新认识,认为塔北草湖凹陷东、西两侧斜坡的形成时间与形成机理存在明显的差异。凹陷西侧中-上奥陶统自东向西超覆沉积特征明显,表明西斜坡主要形成于加里东中期,形成机理是在持续区域挤压背景下,草湖地区相对沉降,阿克库勒地区相对隆升,表现出沉积型凹陷斜坡的特征;而凹陷东侧可见奥陶系、志留系等地层被强烈抬升并遭受剥蚀,角度不整合于上泥盆统-石炭系之下,后者又角度不整合于三叠系之下,表明东斜坡主要形成于加里东晚期和海西早、晚期的强烈构造变形,以海西晚期为主,表现出构造型凹陷斜坡的特征。草湖凹陷西侧有利于发育下奥陶统岩溶型地层圈闭,凹陷东侧有利于发育志留系、石炭系和三叠系超覆型岩性圈闭及中-上奥陶统不整合型地层圈闭、下奥陶统岩溶型地层圈闭,它们是下一步油气勘探的重要方向。
The evolution of Caohu sag in northern Tarim Basin is discussed in this paper based on geological interpretation of two-dimensional seismic profiles and analysis of drilling data .We present new ideas about the evolution of Caohu sag since Paleozoic .The time and mechanism of formation of the eastern and western slopes of Caohu sag are apparently dif-ferent.In the western side of the sag ,the Middle-Upper Ordovician show distinct overlapping characteristics from east to west,indicating that the western slope of Caohu sag was developed mainly in the Middle Caledonian as the result of the subsiding of Caohu area and the uplifting of Akekule Uplift under the continuous regional compression .The western slope has the characteristics of depositional sag slope .While in the eastern side of the sag ,the Silurian-Ordovician were strongly uplifted and eroded and underlie unconformably the Upper Devonian-Carboniferous,which in turn underlie unconformably the Triassic .This demonstrates that the

异常地层压力既是油气运聚的重要动力来源,又是控制油气分布的重要因素。塔里木盆地柯克亚凝析气田新近系西河甫组西八段至古近系卡拉塔尔组油气藏表现出异常高压特征,超高的异常压力为该带油气勘探造成很大制约。从柯克亚凝析气田异常压力特征着手,对异常高压成因进行研究,认为源岩成烃及欠压实作用不是造成该地区超压的主要原因。该地区的超压主要是由侧向构造挤压、构造形变和推覆体加载等构造因素综合作用形成。其中,构造挤压是最主要因素。
Abnormal pressure is not only the major dynamic source of hydrocarbon migration and accumulation, but al-so the important factors for controlling the hydrocarbon distribution.Kekeya condensate gas field,from whose Xi-8 mem-ber of the Neogene Xihefu Formation to the Paleogene Kalatar Formation appears abnormal high pressure. Ultra high ab-normal pressure plays an important role in controlling the oil & gas exploration in this zone. Detailed study on the gene-sis of abnormal pressure has been conducted based on its characteristics. Comprehensive analysis show that:hydrocarbon generation of source rocks and the under-compaction are not the main causes of the overpressure in the region.The over-pressure in this area is mainly formed by combination factors of lateral tectonic compression and structure deformation, loading nappe,of which tectonic compression is the principal factor.
