9、mine whether or not these wells may or may not be economical.（这些信息将会对这些页岩井起到重要作用， 以及能决定这些井是否能有经济效益） In this study, simulations（仿真品） have been conducted with several wellbore configurations for gas production from the Marcellus shale.（在这个研究中，为了马赛勒斯页岩的气体生产， 仿真品被用在一些井眼装置） Some of the parameters（参数） stu

As of 2000, it became even more profitable and thus the emergence of all new gas plays such as the Marcellus,Haynesville and many others.（这主要由于 天然气价格的不断增长，非常规井变的更有经济效益，许多
13、公司更愿意追求他们。就在 2000 年，它变得越来越有经济效益，因此许多新的气藏出现了，列如马赛勒斯，海尼斯维 尼以及其他很多） The Marcellus shale is contained within the Devonian（泥盆纪的） /Ohio（俄亥俄） shale and has an estimated gas in place at 168 516 TCF or 70 150 (BCF/sq mile) (Armas, 2008) (Chernoff, 2008) (Sumi, 2008).（马赛勒斯页岩被含有在泥盆纪俄亥 俄页岩里面和在 168- 516 校正温度 或者

16、is greater for the Marcellus than for other U.S. shales, they concluded, because of premium（优质的，高效的） natural gas pricing due to location and relatively low royalties（矿区使用费） in Appalachia.（内部收益率对马赛勒斯 页岩来说比对其他美国页岩还要重大，他们得出的结论是由于优质的天然气价格所选位置 以及相对来说在阿巴拉契亚较低的矿区使用费） In addition, the Marcellus is estimated to have the lowest breakeven price ($3.17) when compared to Haynesville, Barnett, Fayetteville, and Woodford shales.（此外，与海尼斯维尼，巴尼特，非特维尼和伍德页岩相比马赛勒斯页岩 在价格的估计上
