摘要： A method of actuating at least one of a plurality of downhole tools connected to at least one hydraulic fluid line is disclosed. The method includes the steps of:— a) providing each of the downhole tools with a control unit comprising a timer which permits fluid communication between the at least one hydraulic fluid line and the downhole tool during a window of time; and b) controlling the pressure in the at least one hydraulic fluid line for at least a sufficient period of time required to at least actuate the said downhole tool, wherein the said sufficient period of time coincides at least partially with the said window of time. A control unit for operating one or more than one of a plurality of downhole tools connected to at least one hydraulic fluid line is also disclosed as including a timer associated with each of the one or more downhole tools, the timer permitting hydraulic fluid to communicate with the respective downhole tool if supplied via the at least one hydraulic fluid line during a window of time.A timer apparatus for use in downhole wellbore for permitting controlled activation of a downhole tool at a point in time is also disclosed as including a valve associated with an energy storage mechanism and which is arranged to move the valve when the energy is released to actuate the downhole tool.A system of downhole tools is also disclosed as including two or more downhole tools, at least one hydraulic fluid line, wherein each of the two or more downhole tools is connected to the at least one hydraulic fluid line and at least one control unit comprising at least one timer, wherein each of the one or more downhole tools is connected to a timer, said timer permitting hydraulic fluid to communicate with the respective downhole tool.A method of controlling flow downhole in a wellbore is also disclosed.

摘要： A method of actuating at least one of a plurality of downhole tools (10) connected to at least one hydraulic fluid line (L1, L2) is disclosed. The method includes the steps of: a) providing each of the downhole tools with a control unit (20) comprising a timer which permits fluid communication between the at least one hydraulic fluid line and the downhole tool during a window of time; and b) controlling the pressure in the at least one hydraulic fluid line for at least a sufficient period of time required to at least actuate the said downhole tool, wherein the said sufficient period of time coincides at least partially with the said window of time. A control unit for operating one or more than one of a plurality of downhole tools connected to at least one hydraulic fluid line is also disclosed as including a timer associated with each of the one or more downhole tools, the timer permitting hydraulic fluid to communicate with the respective downhole tool if supplied via the at least one hydraulic fluid line during a window of time. A timer apparatus for use in downhole wellbore for permitting controlled activation of a downhole tool at a point in time is also disclosed as including a valve associated with an energy storage mechanism and which is arranged to move the valve when the energy is released to actuate the downhole tool. A system of downhole tools is also disclosed as including two or more downhole tools, at least one hydraulic fluid line, wherein each of the two or more downhole tools is connected to the at least one hydraulic fluid line and at least one control unit comprising at least one timer, wherein each of the one or more downhole tools is connected to a timer, said timer permitting hydraulic fluid to communicate with the respective downhole tool. A method of controlling flow downhole in a wellbore is also disclosed.

摘要： A downhole actuator (30) comprises a tubular housing (34) which includes an indexing profile (42) on an inner surface thereof, and an indexing sleeve (46) mounted within the housing (34). The indexing sleeve (46) comprises an engaging arrangement including first and second axially spaced engagement members (52, 54) which cooperate with the indexing profile (42) of the housing (34) to be sequentially engaged by an actuation object (48) passing through a central bore (50) of the indexing sleeve (46) to drive the indexing sleeve (46) one discrete step of movement through the housing (34) towards an actuation site.

摘要： A system or apparatus for use in downhole communication or detection comprises a downhole arrangement defining a throughbore and primary and secondary elements. One of the primary and secondary elements is provided on the downhole arrangement and the other of the primary and secondary elements is provided in the throughbore. The primary and secondary elements are configurable for coupling of an electromagnetic field therebetween. The primary or secondary element which is provided in the throughbore may be provided on a tool such as a shifting tool which is deployable through the throughbore. The secondary element may be configured to provide the electromagnetic field coupled between the first and second elements with one or more characteristic features. The system may be configured for use, in particular though not exclusively, for communicating information to and/or from a downhole tool in an oil or gas well.
