中文摘要:    四川盆地西北部双鱼石地区二叠系栖霞组气藏为构造—岩性复合型气藏,气藏埋深7 500 m 左右,储层平面分布具有一定非均质性,单井测试产量存在较大差异。为实现少井高产效益开发目的,尽快摸清栖霞组气藏高产主控因素尤为重要。通过对储层特征、单井产能控制因素的详细分析。结果表明:①栖霞组储层主要发育于颗粒滩经一系列成岩改造形成的白云岩中,根据储层特征分为孔洞型储层和溶洞型储层;②高产井多为孔洞型储层,而溶洞型储层产能较低;③高产井储层在成像测井上表现为较多暗色斑点,而溶洞型储层则表现为暗、亮斑状混杂的特征。
英文摘要:    Most gas reservoirs of Permian Qixia Formation, Shuangyushi area, northwestern Sichuan Basin, are structural-lithologic complex ones with burial depth of 7 500 m. Their areal distribution is heterogeneous, and single-well test production is quite different. In order to achieve one goal of benefit development with a few wells and high yield, it is particularly important to find out the main factors affecting high yield as soon as possible. So, reservoir characteristics of Qixia Formation and some factors controlling
single-well productivity were analyzed in detail. Results show that (1) the gas reservoirs of Qixia Formation are mainly developed in dolomite formed by a series of diagenetic of grain beach, and they can be subdivided into vuggy and cavern reservoirs according to reservoir characteristics; (2) reservoirs in high-yield wells are chiefly vuggy ones whereas and cavern ones for other wells with lower productivity; and (3) in imaging logging, the vuggy reservoirs represent more dark spots whereas chaotic dark and bright spots for
cavern reservoirs
