肯基亚克油田石炭纪孤立碳酸盐台地边缘的储层特征及分类评价

THE CHARACTERISTICS,CLASSIFICATION AND APPRAISAL OF THE RESERVOIRS AT CARBONIFEROUS ISOLATED CARBONATE PLATFORM MARGIN IN KENJIYAK OIL FIELD

  • 摘要: 碳酸盐岩台地是海相碳酸盐岩储层发育的主要环境之一。通过对滨里海盆地东缘肯基亚克油田石炭纪孤立碳酸盐台地储层的沉积和成岩特征分析以及储层预测研究,指出孤立碳酸盐岩台地边缘相带窄,相变快,储层质量明显受沉积和成岩作用共同控制;其中台地边缘礁滩相属浅水高能沉积,成岩作用过程中又经历了较强烈的白云岩化、溶蚀等有利成岩作用的改造,是优质储层发育的最主要相带。总之,肯基亚克油田石炭纪孤立碳酸盐台地独具特色的沉积和成岩作用特征,为类似储层的预测提供了极好的范例。

     

    Abstract: The isolated carbonate platform is one of the major types of environment where marine carbonate reservoir formed.Based on the study of sedimentation and diagenetic characteristics and the prediction of Carboniferous isolated carbonate platform reservoirs of Kenjiyak oil field in the eastern margin of Pre-Caspian basin,this study demonstrates that sedimentary facies are rather narrow there and change fast laterally. The quality of reservoirs is significantly controlled by sedimentation and diagenesis.The shoal facies formed in a shallow high-energy environment along the platform margin is prone to diagenetic alteration such as dolomitization and dissolution,and is therefore the main facies containing high-quality reservoir. The unique depositional and diagenetic characteristics of the Kenjiyak isolated Carboniferous carbonate platform reservoir could provide a clue for reservoir prediction in the oil fields under similar conditions.
