最近的一项FPC研究表明，落基山中蕴藏着高达600万亿英尺的天然气。低渗透白垩系和第三系陆相砂岩。在西北皮肯斯盆地地区，对这类储集岩进行了地表和地下的研究。科罗拉多州。对砂岩的几何形状和方向进行了表征。开发了一种随机相交技术，该技术利用地质信息来生成可用于模拟水力压裂井和核压裂井的动态的一系列储层模型。对核压裂井的油藏模型和非压裂井的油藏模型进行了比较。一般而言，点坝砂岩可用径向模型模拟，河道砂岩可用线性模型模拟。(参考文献23)
A recent FPC study indicated up to 600 trillion ft of natural gas in place in the Rocky Mt. in low permeability Cretaceous and Tertiary, nonmarine sandstones. This type of reservoir rock has been studied in the surface and subsurface in the Piceance Basin area of NW. Colorado. The sandstone geometry and orientation are characterized. A random intersection technique is developed that utilizes the geological information to generate a spectrum of reservoir models that may be used to simulate the performance of hydraulically and nuclearly fractured wells. An example reservoir model for a nuclear fractured well is compared with a reservoir model for a nonfractured well. In general, the point-bar sandstones can be simulated by radial models and the channel sandstones by linear models. (23 refs.)
