Abstract：The Dengying carbonate reservoirs, as one of the primary producing units of ultra-deep hydrocarbon resources in the Sichuan Basin,is required for further studies on their characteristics and controlling factors. This paper focuses on the ultra-deep dolomite of the fourth member of the Dengying Formation in the recently explored Penglai area of the Sichuan Basin. The study examines the reservoir's petrological characteristics,pore spaces,classification of reservoir types,physical properties,diagenetic evolution,and the main controlling factors of the reservoirs. The analysis is based on field outcrop profiles,drilling cores,microsections,cathodoluminescence(CL)imaging,scanning electron microscopy (SEM) data,and physical property test results. The findings are as follows: (1)The primary lithologies of the fourth member of the Dengying Formation in the Penglai area include dolo-thrombolite,dolo-stromatolite,dolo-spongiomicrobialite,and sand-debris dolomite. The main reservoir spaces consist of primary framework pores and secondary dissolution pores formed by subsequent dissolution processes. (2)Fractured reservoirs, primarily composed of dolo-thrombolite and dolo-stromatolite reservoirs with partial bedding pore development, typically exhibit favorable physical properties. The average porosity can exceed 4%,with the average permeability of the former reaching 2.43×10-3 μm2,while the average permeability of the latter is only 0.35×10-3 μm2. (3)A comprehensive analysis of diagenetic evolution reveals that the microbial carbonate reservoirs of the fourth member of the Dengying Formation have undergone a sequence of stages: sedimentary-quasi-symbiotic,supergene,shallow-to-medium burial,and deep-to-ultra-deep burial stages. (4)Analysis of reservoir distribution patterns in the study area indicates that the reservoir distribution weakens from the platform interior to the platform edge. Overall,the ultra-deep dolomite in the fourth member of the Dengying Formation in the Penglai area follows a ternary reservoir model characterized by “sedimentary facies-fault-dissolution.” This study provides key insights into the characteristics and controlling factors of the ultra-deep dolomite reservoirs in the Penglai area of the Sichuan Basin,offering significant guidance for future ultra-deep oil and gas exploration in the region.
