Description

Technical Field

[0001] The utility model relates to the field of nitrogen foam density monitoring devices, in particular to a nitrogen foam density monitoring device suitable for continuous oil pipe operations. Background Art

[0002] Nowadays, nitrogen foam is used in oil pipe operations because the density of nitrogen foam directly affects its performance in the oil pipe or oil well, such as its stability, fluidity and permeability. Therefore, by monitoring the density of nitrogen foam, it is possible to ensure that the quality and stability of the foam are controlled during the injection process to achieve the expected operating effect. The nitrogen foam used in oil field operations is usually a mixture of nitrogen and water. By monitoring the density of the foam, it is possible to ensure that the use of nitrogen can be saved while maintaining the best operating effect, reducing operating costs.

[0003] In the prior art, some devices are capable of monitoring the density of nitrogen foam in real time. These devices usually measure the physical properties of the foam, such as density, consistency or other related parameters, through sensors or other measuring equipment. However, some devices are unable to monitor the density of nitrogen foam at different horizontal positions of the nitrogen foam storage barrel, which will affect the injection of nitrogen foam, resulting in the injection of nitrogen foam of different densities.

[0025] like Figure 1-Figure 3As shown: An embodiment provided by the utility model: A nitrogen foam density monitoring device suitable for continuous tubing operation, including a nitrogen foam density monitor 1, which is used to monitor the density of nitrogen foam, the outside of the nitrogen foam density monitor 1 is fixedly connected with a fixed round tube 2, the inner wall of the fixed round tube 2 is fixedly connected with a connecting rod 3, the outside of the fixed round tube 2 is fixedly connected with a fixed round tube 5, in order to connect part of the device, the outside of the connecting rod 3 is fixedly connected with a connecting tube 4 for passing nitrogen foam, the outside of the connecting tube 4 is slidably fixedly connected with a round table locking rod 6, the connecting tube 4 The outer sliding part is fixedly connected with a truncated cone locking rod 7. In order to clamp and unlock some devices, the outer sliding part of the fixed circular tube 5 is connected with a connecting tube 8 for passing nitrogen foam. The inner wall of the connecting tube 8 is fixedly connected with a limiting ring 9. The outer part of the connecting tube 8 is fixedly connected with a gasket 11.

Push the connecting tube 28 into the fixed circular tube 25, so that the truncated cone locking rod 27 passes the telescopic locking rod 13, and because of the spring 12, the telescopic locking rod 13 rebounds and is stuck by the truncated cone locking rod 27. Continue to push the connecting tube 28, so that the telescopic locking rod 13 passes the truncated cone locking rod 16, and the telescopic locking rod 13 rebounds again. Pull back the connecting tube 28 to let the truncated cone locking rod 16 slide close to the truncated cone locking rod 27. The telescopic locking rod 13 can pass the truncated cone locking rod 27, so that the connecting tube 28 and the fixed circular tube 25 can be easily stuck and opened.
