摘要： Whipstocks and deflectors comprising a degradable composition, and methods of using same are described. In one embodiment the degradable composition consists essentially of one or more reactive metals in major proportion, and one or more alloying elements in minor proportion, with the provisos that the composition is high-strength, controllably reactive, and degradable under defined conditions. Methods of using degradable whipstocks in oilfield operations are also described. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims. 37 C.F.R. 1.72(b).

摘要： A subsea production system includes a blowout preventer stack that is adapted to seal and contain pressure in a well. The blowout preventer stack has a passageway through which a tubular string may extend into the well. The subsea production system includes a subsea wellhead and a safety shut-in system that has a valve assembly that is adapted to control flow and adapted to allow tools to be lowered therethrough on tubing. The subsea production system includes a cutting module that is adapted to be run into the passageway to allow tools to be lowered therethrough on tubing. The cutting module is further adapted to activate to shear the tubing that is lowered therethrough.
摘要翻译：海底生产系统包括适于在井中密封和容纳压力的防喷器堆。防喷器堆叠具有通道，管状柱可以穿过该通道延伸到井中。海底生产系统包括海底井口和安全关闭系统，其具有适于控制流量并适于允许工具在管道上通过其降低的阀组件。海底生产系统包括切割模块，其适于进入通道以允许工具在管道上通过其降低。切割模块还适于激活以剪切通过其下降的管道。

摘要： A cutting module to sever a tubing in a well includes a piston and shear blade. The piston includes at least two moveable telescoping elements, which are adapted to expand the first piston from a retracted length to an expanded length. The shear blade is connected to the piston to sever the tubing in response to the piston expanding from the retracted length to the expanded length. The cutting module may be located below a safety valve in the well.
