Description

Technical Field

[0001] The invention relates to the technical field of cementing operations and relates to an automated cementing multi-channel integrated control device. Background Art

[0002] At present, domestic cementing construction often uses high-pressure pipelines to directly connect ground cementing construction equipment and wellhead cement heads. If there are many types of working fluids, it is necessary to connect multiple high-pressure pipelines between the cementing construction equipment and the cement head or use three-way joints to connect multiple high-pressure pipelines. This construction plan requires more control accessories, connecting multiple pipelines, and installation is time-consuming and labor-intensive. In addition, the working fluid channels connected to the high-pressure pipelines cannot be closed manually or automatically, and it is impossible to achieve rapid switching of multiple high-pressure pipelines. Especially in automated cementing construction operations, it is difficult to automatically control the opening and closing of multiple pipeline channels. In addition, when multiple cement trucks are used to mix cement slurry at the same time, the density of the mixed cement slurry is inconsistent, which affects the cementing quality.

[0003] A Chinese patent document with the publication number CN 107152257 A discloses a multi-channel valve, characterized in that it includes a distributor with a closed structure and provided with a plurality of first inlet pipes, a distribution plate fixedly connected to the distributor, a metering channel arranged on one side of the distribution plate, and a distribution arm rotatably arranged on the other side of the distribution plate, wherein the distribution plate is provided with tube holes corresponding to and connected to the first inlet pipes, and the distribution arm is provided with a U-shaped channel, one end of the U-shaped channel is dynamically sealed and connected to the metering channel, and the other end is dynamically sealed and connected to one end of the first inlet pipe that is not connected to one of the tube holes. The multi-channel valve is used in the field of metering management technology for oil field production. When used in the field of cementing construction, it has the following problems: (1) The channel structure is complex and cement slurry is easily blocked at the U-shaped channel; (2) It cannot withstand excessive pressure and is prone to sealing failure at the connection of the U-shaped channel.

[0004] A Chinese patent document with the announcement number CN 203082272 U discloses a three-way valve, characterized in that it includes a valve body and a valve core, the valve core is located in the valve body, the valve body is provided with a valve body inlet and two valve body outlets, a valve core fluid channel is provided in the valve core, the valve core is rotated in the valve body by an actuator connected to the valve core, characterized in that the valve core fluid channel is connected to the valve body inlet and any one of the valve body outlets, and after the valve core rotates, the valve core fluid channel is connected to the valve body inlet and the other valve body outlet. The three-way valve is used in the field of material transportation, and the following problems may occur when it is used in cementing operations: (1) The three-way valve can only realize dual-channel switching, which is insufficient in terms of function for multi-channel working fluid transportation in cementing construction; (2) The working status indication function cannot be realized; (3) The end face of the valve core is in sliding contact with the valve body, and the rotation friction resistance is large, and it cannot rotate after long-term use.

After the cement head and the cement truck are ready, the cement slurry injection operation can be started. The cement slurry of the two cement trucks flows into the two branch pipes of the grouting pipe 11 and is mixed in the main pipe. The two cement slurries are fully mixed and evenly mixed through the forward blade 21 and the reverse blade 22.
