摘要： An automatic timed shut-in valve for pressure transient testing of a well and the like includes a body member adapted for connection to a locking device for locating the valve at a predetermined point in a tubing string. The valve includes a clock timer and an actuator which is operable to close the valve at a predetermined time after insertion of the valve in the tubing string. Various operations may be carried out including automatic times shut-in of a well or pressure transient testing by recording at least one of pressure and temperature in the well in timed relationship to actuation of the valve so that wellbore and formation conditions can be measured upon shut-in of the well.

摘要： A downhole tool is supported by coilable tubing extending into the wellbore from a tubing injection and withdrawal apparatus and includes an elongated electrical signal transmitting cable extending through the tube between the tool and the injection apparatus. The tool is connected to one end of the tube by a connector assembly which provides for limited swiveling movement of the tool relative to the end of the tube to preclude excessive lateral loads from being exerted on the tool during positioning of the tool in the wellbore. The connector assembly includes a frangible coupling comprising coupling members which are interconnected by shearable pins whereby separation from the tool will occur at the connector assembly in the event the tool becomes stuck in the wellbore. One of the coupling members includes a fishing neck for engagement with a suitable fishing tool whereby the downhole tool may be retrieved if separated from the tubing. Fluids may be pumped downhole through the tube and the connector assembly to provide improved downhole operating methods.
摘要翻译：井下工具由从注油和取出装置延伸到井眼中的可卷曲管道支撑，并且包括延伸穿过工具和注射装置之间的管的细长电信号传输缆索。该工具通过连接器组件连接到管的一端，该连接器组件提供工具相对于管的端部的有限的旋转运动，以防止在将工具定位在井筒中时过度的横向载荷施加在工具上。连接器组件包括易碎联接器，其包括由可剪切销钉相互连接的联接构件，从而在工具卡在井眼中的情况下，在连接器组件处将发生与工具的分离。联接构件中的一个包括用于与适当的钓鱼工具接合的钓鱼脖子，从而如果与管道分离则可以取出井下工具。流体可以通过管和连接器组件井下泵送，以提供改进的井下操作方法。
