摘要： A device, system, and method for locating collars along a casing string. The device includes a casing collar locator (CCL) and a valve in communication with the CCL connected to a work string. Fluid is pumped down the work string as the device is used to locate collars along a string. Upon detection of a collar, the CCL sends a signal to the valve, which causes the actuation of the valve to decreases a flow area within a work string. The decrease in flow area causes a pressure increase within the work string, which may be detected at the surface to indicate the detection of a collar. The device may include an amplifier and power source to amplify the signal from the CCL to the valve. The CCL may detect collars by a change in magnetic flux or by the detection of a signal emitted by individual collars.

一种用于沿套管柱定位套环的装置，系统和方法。该装置包括套管接箍定位器（CCL）和与连接到工作管柱的CCL连通的阀。由于该装置用于沿着绳子定位套环，因此流体沿着工作管柱泵送。在检测到轴环时，CCL向阀发出信号，这引起阀的致动以减小工作管柱内的流动面积。流动面积的减小导致工作管柱内的压力增加，其可在表面处被检测到以指示检测到套管。该设备可能包括一个放大器和电源来放大从CCL到阀门的信号。 CCL可能会通过磁通量的变化或通过检测单个项圈发出的信号来检测项圈。

摘要： An intelligent dart or ball or other shape is dropped or pumped into a borehole that has multiple valves for access to the formation through which fractures are initiated. The intelligent object engages with the valves as it passes with retractable engagement dogs that are outwardly biased but not to the degree needed to find support unless the valve in question is the one that needs to be operated. In that event the dogs become supported and pressure is applied to the object to shift the valve to the open position. The object can be released at a later time remotely or can be milled out. Subsequent objects can be landed in the same sleeve after the initial object is released to close it or to close the open port by moving a second sleeve against a first sleeve. Fracturing in any order is envisioned.
