摘要: 明确塔里木盆地肖尔布拉克组储层的品质、规模及分布规律对指导寒武系盐下领域的勘探具有重要意义。通过对柯坪地区苏盖特布拉克剖面的解剖，阐明了肖尔布拉克组主要发育与藻（蓝细菌）有关的微生物白云岩（层纹石白云岩、凝块石白云岩、叠层石白云岩和藻格架白云岩）、黏结藻屑白云岩、藻砂屑白云岩、泥-粉晶白云岩和含砂屑泥-粉晶白云岩，自下而上的岩相组合指示缓坡型台地沉积特征；孔隙类型主要为溶蚀孔洞，粒（晶）间溶孔和藻格架溶孔，总体具有中高孔-中低渗的特征，孔隙的发育与岩相具有明显的相关性，其中藻砂屑白云岩和具有格架结构的微生物白云岩储层物性最好；通过二维地质建模及基于数字露头的三维地质建模，揭示了肖尔布拉克组储层具有较好的层位性、相控性和规模性，古隆起围斜部位的中缓坡丘滩体是储层发育的有利相带。

Abstract: Studying the quality and distribution law of the Xiaoerblak Formation (Fm.) is significant for guiding the exploration of Cambrian sub-salt area. The quality and scale of the reservoir are the main factors causing the restriction of further exploration in the Xiaoerblak Fm. of the Lower Cambrian, Tarim Basin. This study takes the Sugaiteblak Section in the Keping area as an example. Based on the detailed description, physical properties analysis, and three-dimensional (3D) reservoir geological modeling in the Xiaoerblak Fm., we found that microbial dolomite (including laminate, thrombolite, stromatolite, and microbial framework dolomite), dolarenite, and muddy to micritic dolomite are the main rock types indicating the sedimentary characteristics of the ramp. Vugs, intergranular dissolved pores (or intercrystalline pores), and framework pores are the main reservoir spaces, which have an obvious correlation with lithofacies. Among them, dolarenite and microbial framework dolomite are the most favorable reservoir rocks. Generally speaking, the reservoir has characteristics of middle-high porosity and middle-low permeability. The scale development of the reservoir was controlled by a high frequency sequence and sedimentary microfacies, and microbial mounds and shoals in the middle ramp around the ancient uplift are the favorable facies zones.
