| titleOfInvention | The electric control system of sleeve pipe toe-end intelligence sliding sleeve |
| abstract | The utility model discloses the electric control system of sleeve pipe toe-end intelligence sliding sleeve, including pressure sensor, sensor signal transmitting circuit, microprocessor, detonation chain, explosive cord, the lined-cavity charge being sequentially connected, in addition to power supply；Pressure sensor is used to detect wellbore fluid pressure change and pressure change is transformed into physical arrangement variable quantity；Sensor signal transmitting circuit is used to the physical arrangement variable quantity of pressure sensor is converted into data signal and is sent to microprocessor；Microprocessor is used to interpret effective control command to deliver to detonation chain；Detonation chain detonation of shaped charges；Lined-cavity charge is used to trigger sliding sleeve unlatching.The utility model, which avoids, uses larger sliding sleeve Opening pressure value, pressure change in sleeve pipe is detected by pressure sensor, so as to open sliding sleeve by the lined-cavity charge that detonates, reduces the cost for opening sliding sleeve, danger is reduced, improves the chance of success that sliding sleeve is accurately opened. |
