摘要： The present disclosure addressed apparatus and methods for forming an annular isolator in a borehole after installation of production tubing. Annular seal means are carried in or on production tubing as it is run into a borehole. In conjunction with expansion of the tubing, the seal is deployed to form an annular isolator. An inflatable element carried on the tubing may be inflated with a fluid carried in the tubing and forced into the inflatable element during expansion of the tubing. Reactive chemicals may be carried in the tubing and injected into the annulus to react with each other and ambient fluids to increase in volume and harden into an annular seal. An elastomeric sleeve, ring or band carried on the tubing may be expanded into contact with a borehole wall and may have its radial dimension increased in conjunction with tubing expansion to form an annular isolator.

摘要： The current invention provides methods for determining the sand production rate from unconsolidated and poorly consolidated subterranean formations under varying drawdown pressures. The current invention also allows for immediate production of fluid from the subterranean formation upon determination of the sand production rate. Additionally, the current invention provides a method for determining the detrimental sand production rate and/or the maximum sand free production rate for a subterranean formation. Finally, the current invention is applicable in vertical, horizontal, deviated and multi-lateral boreholes.

摘要： Improved methods and apparatus for completing a subterranean zone penetrated by a wellbore are provided. The improved methods basically comprise the steps of placing a sand control screen (e.g., screens, screened pipes, perforated liners, prepacked screens, etc.) and an outer shroud assembly mounted over the sand screen in the wellbore adjacent the zone to be completed, the shroud having perforated and blank (non-perforated) segments with the blank segments corresponding to selected intervals of the wellbore, for example problem zones such as shale streaks or isolated zones where flows are restricted by mechanical seals or packers, and injecting particulate material into the wellbore, whereby gravel packing takes place in the remaining length of the wellbore/shroud annulus without voids. The inner annulus between the shroud and screen provides an alternate flow path for the slurry to bypass the blocked intervals and continue with its placement. Mechanical seals or packers may be used in combination with the shroud and associated sand screen. The method is also applicable to placing gravel packs in a cased and perforated well drilled in the zone.
摘要翻译： 提供了用于完成由井眼穿透的地下区域的改进的方法和装置。 改进的方法基本上包括以下步骤：在邻近待完成区域的井眼中放置防砂筛（例如筛网，筛管，穿孔衬垫，预包装筛网等）和安装在井筒上的砂筛上的外护罩组件， 具有穿孔和空白（非穿孔）段的护罩具有对应于井眼的选定间隔的空白区段，例如诸如页岩条纹或隔离区域的问题区域，其中流被机械密封件或封隔器限制，并且将颗粒材料注入 井眼，因此在没有空隙的井筒/护罩环的剩余长度内进行砾石填充。 护罩和屏幕之间的内环提供了一种替代的流动路径，用于使浆料绕过堵塞的间隔并继续其放置。 机械密封或封隔器可以与护罩和相关的砂筛组合使用。 该方法也适用于将砾石填充物放置在在该区域钻出的套管和穿孔井中。
