Description

Technical Field

[0001] The utility model relates to the technical field of bridge plug detection, in particular to a bridge plug detection device. Background Technique

[0002] The bridge plug mainly uses the special opening shape and size of the bridge plug body to form an insurmountable barrier in the wellbore, so as to realize layer isolation. When the bridge plug is lowered into the wellbore and reaches the predetermined position, the release mechanism is activated under preset conditions, so that the bridge plug body is separated from the release mechanism. The bridge plug body unfolds and anchors in the wellbore. At this time, the bridge plug body forms an insurmountable bridge, dividing the wellbore into upper and lower parts to achieve the purpose of isolating layers. Before the bridge plug is put into use, it is necessary to detect the bridge plug to prevent inferior bridge plugs from being put into use.

[0003] After the applicant's search for existing bridge plug detection devices, the bridge plug pressure test device disclosed in Chinese Patent No. CN215726551U includes a pressure test pipeline, a connector, a pressure test sleeve, a core rod and a pressure cap. One end of the connector is connected to the pressure test sleeve, and the other end is an uneven structure. One end of the core rod can be embedded in the concave part of the uneven structure, and the first included angle between the sealing surface of the concave part at the connection and the horizontal plane is greater than the second included angle between the sealing surface of one end of the core rod and the horizontal plane. Therefore, there is a gap between the sealing surface of the concave part and the sealing surface of one end of the core rod. Through this gap, a certain space can be reserved for the deformation of the core rod and the connector during the sealing process, ensuring the sealing performance between the connector and the core rod, and the connector will not be damaged after long-term use. In this way, it is not necessary to frequently replace the connector, thereby reducing the cost of detecting the sealing performance of the bridge plug.

[0004] However, the applicant found that when using the pressure test device to detect the sealing performance of the bridge plug, the detected is the sealing performance when the bridge plug is set, and the sealing performance inside the bridge plug body cannot be precisely detected. When the sealing performance inside the bridge plug body is not good, the use effect of the bridge plug is poor, and even it cannot be set.

[0005] Therefore, in view of the above problems, it is necessary for the applicant to design a bridge plug detection device to solve the problems. Summary of the Invention
