摘要： Determination of the rate penetration (ROP) of drilling has usually been based upon surface measurements and may not be an accurate representation of the actual ROP. This can cause problems in Logging While Drilling (LWD). Because of the lack of a high-speed surface to-downhole communication while drilling, a conventional method of measuring ROP at the surface does not provide a solution to this problem. However, the instantaneous ROP can be derived downhole with a certain degree of accuracy by utilizing an accelerometer placed in (or near) the tool to measure acceleration in the axial direction. When three-component accelerometers are used, the method may be used to determine the true vertical depth of the borehole.
摘要翻译：钻孔的速率穿透（ROP）的确定通常基于表面测量，并且可能不是实际ROP的精确表示。这可能会导致钻井记录（LWD）中的问题。由于在钻孔时缺乏高速的井下通信，传统的测量表面ROP的方法不能解决这个问题。然而，可以通过利用放置在工具（或附近）中的加速度计来测量轴向方向上的加速度，从而在一定程度上精确地导出瞬时ROP。当使用三分量加速度计时，该方法可用于确定钻孔的真实垂直深度。

摘要： A system for reverse circulation in a wellbore include equipment for supplying drilling fluid into the wellbore bit via at least an annulus of the wellbore and returning the drilling fluid to a surface location via at least a bore of a wellbore tubular. The system also includes devices for controlling the annulus pressure associated with this reverse circulation. In one embodiment, an active pressure differential device increases the pressure wellbore annulus to at least partially offset a circulating pressure loss. In other embodiments, the system includes devices for decreasing the pressure in the annulus of the wellbore. For offshore application, annulus pressure is decreased to accommodate the pore and fracture pressures of a subsea formation. In still other embodiments, annulus pressure is decreased to cause an underbalanced condition in the well

摘要： One exemplary APD Device (173) is used with a liner drilling assembly (135) to control wellbore pressure. The APD Device reduces a dynamic pressure loss associated with the drilling fluid (142) returning via a wellbore annulus (154). Another exemplary APD Device is used to control pressure in a wellbore when deploying wellbore equipment, including running, installing and/or operating wellbore tools. The APD Device is set to reduce a dynamic pressure loss associated with a circulating fluid. The APD Device can also be configured to reduce a surge effect associated with the running of the wellbore equipment. Still another APD Device is used to control pressure in a wellbore when completing or working over a well. Exemplary completion activity can include circulating fluid other than a drilling fluid, such as a gravel slurry. The APD Device can reduce the dynamic pressure loss associated with circulation of both drilling fluid and non-drilling fluid.
