【摘要】 新场构造位于四川省德阳市境内,位于该构造范围内的上三叠统须家河组二段气藏目前已有5口井获得了工业气流,其中有3口井还获得了高产工业气流,展示出巨大的勘探开发潜力。为此,结合地震、地质、钻井、测井及测试等资料,研究了该构造须家河组二段气藏的构造、储层、成藏特征。结果认为:新场地区须家河组二段具备规模成藏的圈闭条件,储层砂体发育,裂缝对于改善储层的储渗条件以及获得高产气井发挥着至关重要的作用;"强相位中段,杂乱弱反射特征"为有利储渗体("甜点")的宏观地震响应;今构造对油气调整、富集有着重要的控制作用。更多还原

【Abstract】 Xinchang structure is located within the boundary of Deyang city, Sichuan province. The gas pool in the Upper Triassic Xujiahe Formation of Xinchang structure currently has 5 wells with tested industrial gas flow, 3 of which are highly gas-rate wells, indicating large exploration and development potentials. Seismic, geologic, drilling, logging and testing data are integrated to study the characteristics of the structures, reservoirs, and hydrocarbon accumulation in this gas pool. The second member of Xujiahe Formation in Xinchang area has the trapping conditions for large scale hydrocarbon accumulation and highly-developed sandbodies. In addition, fractures also play a critical role in improving poroperm characteristics of the reservoirs and drilling highly gas-rate wells. The macroscopic seismic responses of favorable reservoir body (sweet point) are "middle part of strong phase and chaotic weak reflectance signatures". Present structures have a strong control on the adjustment and enrichment of oil and gas.更多还原
