摘要： The present generally relates to apparatus and methods for instrumentation associated with a downhole deployment valve or a separate instrumentation sub. In one aspect, a DDV in a casing string is closed in order to isolate an upper section of a wellbore from a lower section. Thereafter, a pressure differential above and below the closed valve is measured by downhole instrumentation to facilitate the opening of the valve. In another aspect, the instrumentation in the DDV includes sensors placed above and below a flapper portion of the valve. The pressure differential is communicated to the surface of the well for use in determining what amount of pressurization is needed in the upper portion to safely and effectively open the valve. Additionally, instrumentation associated with the DDV can include pressure, temperature, seismic, acoustic, and proximity sensors to facilitate the use of not only the DDV but also telemetry tools.

摘要： The valve operator of the present invention provides an apparatus and method for reducing torque necessary for opening and closing a valve, such as a quarter-turn rotary valve. In the preferred embodiment, an outer handle adaptor has inner curved tracks that drive balls positioned in straight slots of a middle cylinder. As the balls move in the straight slots, they transfer torque energy to a valve shaft adaptor mounted within the middle cylinder and having outer curved threads that mesh with the balls. The pitch of the curved tracks of the outer handle differ from the pitch the curved tracks of the valve shaft adaptor to thereby effect a desired torque reduction ratio. The valve operator has relatively few components, at least three or more relatively rotatable components, preferably arranged in meshing configuration so as to effect a small size operator without the use of a gear box. The size of the operator is so small that it is comparable or the effectively the same as that of a valve having a simple straight-shaft valve operator.

摘要： Apparatus and methods for a deployment valve used with an underbalanced drilling system to enhance the advantages of underbalanced drilling. The underbalanced drilling system may typically comprise elements such as a rotating blow out preventer and drilling recovery system. The deployment valve is positioned in a tubular string, such as casing, at a well bore depth at or preferably substantially below the string light point of the drilling string. When the drilling string is above the string light point then the upwardly acting forces on the drilling string become greater than downwardly acting forces such that the drilling string begins to accelerate upwardly. The deployment valve has a bore sufficiently large to allow passage of the drill bit therethrough in the open position. The deployment valve may be closed when the drill string is pulled within the casing as may be necessary to service the drill string after drilling into a reservoir having a reservoir pressure. To allow the drill string to be removed from the casing, the pressure produced by the formation can be bled off and the drill string removed for servicing. The drill string can then be reinserted, the pressure in the casing above the deployment valve applied to preferably equalize pressure above and below the valve and the drill string run into the hole for further drilling.
摘要翻译： 用于与欠平衡钻井系统一起使用的展开阀的装置和方法，以增强欠平衡钻井的优点。 欠平衡钻井系统通常可以包括诸如旋转防喷器和钻井恢复系统的元件。 展开阀定位在诸如壳体的管状柱中，在钻井深度处的井眼深度处或优选地基本上低于钻柱的弦光点。 当钻柱高于弦灯点时，钻杆上的向上作用的力将大于向下作用的力，使得钻柱开始向上加速。 展开阀具有足够大的孔，以允许钻头在打开位置通过其中。 当钻柱在壳体内被拉动时可以关闭展开阀，这可能是在钻进具有储层压力的储存器中之后维护钻柱所需要的。 为了允许将钻柱从壳体中移除，由地层产生的压力可以被排出并且钻柱被移除用于维修。 然后可以重新插入钻柱，施加在展开阀上方的壳体中的压力以优选地使阀上方和下方的压力平衡，并且钻柱进入孔以用于进一步钻孔。
