【摘要】 塔里木盆地北部三叠系储层为一套低成熟度砂岩,其成岩作用的最大特点是浅埋环境及早期成岩阶段所发生的成岩作用较弱,深埋环境成岩作用占主导地位,而且以改善储集性能的建设性作用为主,最高成岩演化阶段为中成岩期成熟阶段"A"。更多还原

【Abstract】 The Triassic reservoir in the Northern Talimu(Tarim)Basin is a sort of the low ma- ture sandstones,the main characteristic of which is inactive for the diageneses taking place in the shallow-burial realm and on the early diagenetic stage,while the diagenesis in the deep-lying realm occupies the first position and playing a constructive role especially in improving the storage capacity.The highist diagenetic stage is the mature stage"A"in the middle diagenesis.更多还原
