Problems solved by technology

[0004] This method requires the antenna, reader, battery, motor, locking device, etc. to be built into the sliding sleeve in advance. These electrical components need to be placed underground for a long time following the sliding sleeve, and the high temperature resistance performance of each electrical component is required. The longer the time the components are placed downhole, the lower the reliability of identification, and the lower reliability of identification has occurred in actual operation

Embodiment 1

[0031] Such as Figure 1-Figure 6 As shown, a multi-stage fracturing intelligent control system includes a casing joint 1 , a sliding sleeve 2 and an intelligent delivery device 3 .

[0032] The sliding sleeve 2 is connected between two adjacent sleeve pipe joints 1, and each of the sliding sleeves 2 includes a sliding sleeve outer tube 24 and a sliding sleeve inner tube 25 connected by socket connection. The outer tube 24 is provided with a liquid outlet hole 23, and the inner tube 25 of the sliding sleeve is connected with the outer tube 24 of the sliding sleeve through a locking device 22 (such as a pin, etc.), and the inner tube 25 of the sliding sleeve is opposite to the outer tube 24 of the sliding sleeve. The liquid outlet hole 23 is blocked.

[0033] The rear portion of the inner tube 25 of the sliding sleeve is also provided with a limiting part 26, the limiting part 26 and the outer tube of the sliding sleeve 24 are integrally formed structural parts, and the inner ...

Abstract

The invention discloses an intelligent putting device. The intelligent putting device comprises an antenna, a reader, a battery, a driving mechanism, an executing mechanism and a limiting mechanism, wherein the antenna is used for receiving an electromagnetic signal of an electronic tag on a sliding sleeve, the reader is connected with the antenna and is used for identifying the received electromagnetic signal, the driving mechanism is connected with the reader, the reader is used for controlling the driving mechanism to act after identifying the electromagnetic signal, the executing mechanism is connected with the driving mechanism, the limiting mechanism is connected with the executing mechanism, the driving mechanism is used for driving the executing mechanism to act and enabling the limiting mechanism to extend out of the intelligent putting device, the limiting mechanism can be abutted with an inner pipe of the sliding sleeve and is used for pushing the inner pipe of the sliding sleeve to slide relative to an outer pipe of the sliding sleeve, so that a liquid outlet in the sliding sleeve is exposed, and the battery is connected with the antenna, the reader and the driving mechanism and is used for supplying power to the intelligent putting device.

Description

technical field [0001] The invention relates to the technical field of oil and gas development, in particular to an intelligent delivery device. Background technique [0002] The existing casing sliding sleeve opening procedure needs to destroy or unlock the sliding sleeve locking device first, and then open the sliding sleeve, thereby exposing the holes of the liquid flow path, the liquid enters the formation through the holes, and creates cracks in the formation through high-pressure hydraulic force, thereby effectively Exploitation of oil and gas resources in the formation. In order to maximize the exploitation of oil and gas resources in the formation, there are usually multiple casing sliding sleeves in a well, and each casing sliding sleeve corresponds to its corresponding formation. If during the casing pressure test, a certain level of sliding sleeve is opened in advance, the formation below this level will not be able to carry out hydraulic fracturing normally. ...
