Problems solved by technology

The technology of this method is relatively complicated, the drilling time is not easy to grasp, the operability is poor, and the drilling accuracy is not high, which will adversely affect the test results
[0004] In addition, in the current living and other projects, it is also necessary to drill horizontal boreholes in vertical boreholes, but there is no suitable device for drilling

Abstract

The invention discloses a perforation drilling device and method in a vertical borehole. The device includes a hollow cylinder that can be placed in the vertical borehole. A supporting part is provided at the bottom of the hollow cylinder. There is a slideway hingedly connected with the bottom of the hollow cylinder in the opening, the drill with the drill bit is arranged on the slideway and the driller can slide along the slideway; one end of the drill bit of the driller is connected with the first wire rope on the first winch, and the first The winch drives the drilling rig forward on the slideway through the first wire rope to drill, the other end of the drill is connected to the second wire rope on the second winch, and the second winch drives the drill back on the slideway through the second wire rope; The drilling device is installed in the hole to avoid the complexity of the drilling method in the prior art. The whole device can realize drilling and perforation in the vertical drilling hole, which is easy to operate and has high precision. Pick.

Description

technical field [0001] The invention relates to a drilling mechanism, in particular to a perforation drilling device and method for vertical drilling. Background technique [0002] With the development of my country's economy and society, more and more underground vertical boreholes are being built, and related experiments on simulating vertical borehole mining are becoming more and more common. Among them, the core hydraulic fracturing test is a relatively common test method for simulating on-site oil and gas production. [0003] In this test, a cube rock block of 500mm×500mm×500mm is usually used to simulate the infinite formation in the actual project, and a vertical hole with a diameter of about 100mm or even larger is drilled from the geometric center of the outer surface of the rock block toward the core. Or a smaller diameter of 50-80mm, and put it into the casing to simulate the oil well in the actual project, drill the diameter of about 10-20mm into the rock format...
