    Characteristics of Ordovician carbonate reservoirs in the western plunge of Guchengxu uplift, Tarim basin

    • 摘要: 提要:塔里木盆地古城墟隆起西端发现了多层奥陶系碳酸盐岩储层,深入分析其储层特征及形成机理,对油气勘探开发具有重要意义。为此利用该研究区内岩心和测井资料,对该区的奥陶系碳酸盐岩储层类型和特征进行了研究,发现该区存在多种储层类型。结合研究区的构造演化特征和岩溶系统的分析,并通过与塔河地区的储层进行对比认为储层的原生孔隙、裂缝是次生孔隙和形成的基础条件,而构造运动产生的裂缝是促进岩溶发育、控制储集体发育的关键因素,而古城墟隆起西端内幕岩溶型储层主要发育在6300 m以下。进一步应用振幅变化率、相干体分析等技术,有效预测了古城墟隆起西端的岩溶型碳酸盐岩储层发育区。
      Abstract: Abstract:Multiple-layer Ordovician carbonate reservoirs have been discovered in the western plunge of Guchengxu uplift, Tarim basin, and it is important for the petroleum exploration workers to analyze characteristics and controlling factors of the reservoirs. Based on well core data and logging curves, the authors identified many kinds of reservoirs in the study area. Combined with structural evolution and karst system in the study area and compared with reservoirs in Tahe area, it is believed that the original porosity and fractures constituted the fundamental prerequisites for the formation of secondary pores, and the fractures caused by structural movement seemed to be crucial to the accelerated growth and development of karst and reservoirs. The karst reservoir grew under the depth of 6300 m in the western plunge of Gechengxu uplift. To effectively predict the karst carbonate zones, the authors also employed such technologies as amplitude variation and coherent cube analysis, which yield satisfactory results.
