摘要： 阿姆河右岸区块油气资源丰富，东部地区近期发现的单体规模较大的碳酸盐岩“断缝体”气藏，展示了该区碳酸盐岩十分优越的天然气成藏条件。利用地震、岩心薄片及钻测井资料，宏观微观相结合，开展上侏罗统碳酸盐岩“断缝体”天然气成藏富集规律研究。认为研究区在控圈断层、改造断层及微断层3 类不同级别断层和丘滩体、灰泥丘及滩间3 类沉积环境下，受伴生溶蚀流体作用形成储渗结构差异较大的丘滩体—控圈断层、丘滩间—控圈断层、丘滩体+ 改造断层、丘滩间+ 改造断层、丘滩体+ 微断层和丘滩间+ 微断层等不同规模的6 类“断缝体”储层，是阿姆河右岸东部地区一种新的储集体类型天然气藏。结合几类已投产的“断缝体”气藏的开发地质参数，将该类气藏进一步细分为Ⅰ类控圈（构造带）断层强破裂+ 强溶蚀的规模断缝体气藏；Ⅱ类改造断层附近中破裂+中溶蚀的局部断缝气藏和Ⅲ类微断层弱破裂+ 未溶蚀的裂缝—孔隙型或裂缝型气藏，其中Ⅰ类气藏在储量规模和高产稳产方面优势明显，是该地区下一步深挖勘探潜力的主要目标类型。

Abstract: The oil and gas resources in the Amu Darya Right Bank are abundant. Recently, a large-scale carbonate “ fault-fracture “ gas reservoir was discovered in the eastern region, demonstrating the excellent natural gas accumulation conditions of the carbonate rocks in this area. This study integrates seismic, core, thin section, and drilling log data to investigate the gas accumulation and enrichment patterns in the Upper Jurassic carbonate “ fault-fracture reservoir.” The study suggests that in the research area, under three different levels of faults—controlling faults, transformed faults, and micro-faults—and three types of depositional environments—shoal, mud mound, and intershoal environments—the interaction with associated corrosive fluids has led to the formation of fault-fracture with varying reservoir and permeability characteristics. These fault-fracture reservoirs include six types: shoal body-controlling fault, shoal body-intershoal-controlling fault, shoal body + transformed fault, shoal body + micro-fault, intershoal body + transformed fault, and intershoal body + micro-fault. These six types represent a new type of gas reservoir in the eastern part of the Amu Darya Right Bank. Based on the development geological parameters of several already producing “ fault-fracture “ gas reservoirs, these reservoirs can be further classified into three categories: Type I—large-scale fault-fissure bodies with strong fractures and strong corrosion near controlling faults (structural belts); Type II—local fault-fracture bodies with moderate fractures and moderate corrosion near transformed faults; and Type III—fracture-pore or fracture-type gas reservoirs with weak fractures and no corrosion in micro-faults. Among these, Type I reservoirs, with their significant advantages in reserve scale and stable high production, are the main target for further exploration potential in the region.
