摘要: 通过钻井岩心描述、薄片鉴定及测井分析等手段,对塔里木盆地顺北地区奥陶系一间房组成岩相进行了综合分析,共划分出溶蚀相、白云石化相、裂缝相、胶结相和热液相,以及8类成岩亚相:大气淡水溶蚀亚相、埋藏溶蚀亚相、断裂溶蚀亚相、准同生云化亚相、埋藏云化亚相、海水胶结亚相、淡水胶结亚相和埋藏胶结亚相;5种复合成岩相:胶结-热液相、裂缝-溶蚀相、裂缝-胶结相、裂缝-热液相和云化-胶结-热液相。该区海侵体系域发育海底胶结成岩亚相;高位域时为构造热液相、胶结相等;台内滩沉积亚相多发育大气淡水溶蚀亚相、大气淡水胶结亚相及少量的构造-热液相;滩间海沉积亚相发育埋藏云化亚相、溶蚀相和胶结相;台内礁沉积亚相发育大气淡水溶蚀和大气淡水胶结亚相。在构造、沉积相和层序的控制下,利用单井、成岩相连井及均方根振幅属性,对成岩相演化进行了点线面识别,顺北地区有利成岩相的分布是从南西方向逐渐向北东方向过渡。Abstract: The diagenetic facies of the Ordovician Yijianfang Formation in the Shunbei area of the Tarim Basin was analyzed using drilling core description, thin section observation, as well as logging trace and seismic data analysis. There are five diagenetic facies types: dissolution, dolomitization, fracture, cementation and hydrothermal facies, which were further divided into eight subfacies: atmospheric freshwater dissolution, burial dissolution, fracture dissolution, penecontemporaneous dolomitization, burial dolomitization, subsea cementation, freshwater cementation, and burial cementation. Five composite diagenetic facies were identified: cementation-hydrothermal, fracture-dissolution, fracture-cementation, fracture-hydrothermal, and dolomitization-cementation-hydrothermal facies. The subsea cementation subfacies was developed in the low system tract, while the tectonic-hydrothermal and cementation subfacies were developed in the high system tract. In intraplatform beach sediments, atmospheric freshwater dissolution and atmospheric freshwater cementation subfacies, and a small amount of tectonic-hydrothermal subfacies developed. In interstitial marine sediments, there developed burial dolomitization, dissolution and cementation subfacies. In intraplatform reef sediments, atmospheric freshwater dissolution and atmospheric freshwater cementation subfacies occur. The diagenetic facies evolution was controlled by tectonics, sedimentary facies and sequence and constrained by point, single well profiles, diagenetic facies connected wells and root mean square amplitude attributes. The distribution of favorable diagenetic facies in the Shunbei area is gradually transitions from the southwest to the northeast.
