| 摘要 |
A downhole tool including a body having one or more openings. A main sleeve is disposed in the body. The main sleeve is configured to move between a first position in which the main sleeve blocks fluid flow through the one or more openings and a second position in which the main sleeve allows fluid flow through the one or more openings. An actuator is disposed in the body. The actuator is configured to actuate from a first state to a second state in response to application of a first level of pressure, and to a third state in response to application of a second level of pressure. Actuating the actuator to the third state causes the main sleeve to move from the first position to the second position, and the second level of pressure is less than or equal to the first level or pressure. |

1. A downhole tool, comprising:
a body having one or more openings; a main sleeve disposed in the body, the main sleeve being configured to move between a first position in which the main sleeve blocks fluid flow through the one or more openings and a second position in which the main sleeve allows fluid flow through the one or more openings; and an actuator disposed in the body, the actuator being configured to actuate from a first state to a second state in response to application of a first level of pressure, and to a third state in response to application of a second level of pressure, wherein actuating the actuator to the third state causes the main sleeve to move from the first position to the second position, and wherein the second level of pressure is less than or equal to the first level or pressure. |
