Problems solved by technology

[0002] The double-ended water stopper is the main equipment for segmented water injection observation in downhole upholes. At present, the double-ended water stopper used for observing the borehole only has the function of detecting the borehole, and does not have the function of peeping or photography. And when people use the double-ended water stopper to detect whether there is water seepage in the borehole, the double-ended water stopper needs to provide a relatively sealed environment. However, the contact area between the existing double-ended water stopper and the borehole is small , and the plugging capsule is only a single layer, it may be cut by drilling, and the safety is low

Embodiment Construction

[0028] Such as figure 1 As shown, in this embodiment, a double-ended water stopper device with integrated borehole peeping function includes a first housing 1, a second housing 28, a water injection assembly, an inflatable assembly, a peeking assembly and a blocking assembly. The first housing 1 and the second shell 28 are movably connected, the water injection assembly is set in the first shell 1 and the second shell 28, and the inflatable assembly is set in the first shell 1 and the second shell 28, by setting the water injection assembly and the inflation assembly, when people use the device to detect whether there is water seepage in the borehole, the water injection assembly injects water into the second blocking capsule 6 and the fourth blocking capsule 24, and the inflation assembly will press the high pressure Gas is injected into the first plugging capsule 3 and the third plugging capsule 23, so that the first plugging capsule 3 and the third plugging capsule 23 are i...

Abstract

The invention discloses a double-ended water blocking device with integrated drilling and peeping function. The casings are movably connected, the water injection assembly is disposed in the first casing and the second casing, the inflation assembly is disposed in the first casing and the second casing, and the blocking assembly is disposed in the first casing and the second casing. the first housing and the second housing surface, and the peeping assembly is located between the first housing and the second housing. In the invention, the peeping device probe is arranged in the middle of the two capsules of the double-ended water blocking device, so as to realize the omnidirectional observation of the borehole wall, and the display screen of the peeping device probe is connected, and the peeping device probe can help people to check the real situation in the borehole. At the same time, it can also shoot and record the situation in the borehole for people, and it is convenient for people to record and analyze the situation of the borehole.

Description

technical field [0001] The invention relates to the technical field of water stoppers. Specifically, it is a double-ended water stopper device and method with an integrated drilling peeking function. Background technique [0002] The double-ended water stopper is the main equipment for segmented water injection observation in downhole upholes. At present, the double-ended water stopper used for observing the borehole only has the function of detecting the borehole, and does not have the function of peeping or photography. And when people use the double-ended water stopper to detect whether there is water seepage in the borehole, the double-ended water stopper needs to provide a relatively sealed environment. However, the contact area between the existing double-ended water stopper and the borehole is small , and the plugging capsule is only a single layer, it may be cut by drilling, and the safety is low. Contents of the invention [0003] Therefore, the technical proble...
