Description

Technical Field

[0001] The present invention relates to the technical field of mine water hazard prevention and control, and in particular to a directional drilling layer control method, device and computer program product. Background Art

[0002] In recent years, as coal mining and grouting have moved deeper, the thickness of the coal seam floor aquifer has become thinner and thinner, and the water pressure it bears has become greater and greater, and the probability and danger of floor water inrush have increased year by year. Floor water inrush refers to the phenomenon that the water in the pressure-bearing aquifer of the coal seam floor, under the action of water pressure, mine pressure and other factors, overcomes the resistance of the rock strength, faults, joints and other structural surfaces between the coal seam and the karst aquifer relative to the aquifer, and suddenly flows into the working face or tunnel through the water channel formed by the destruction surface formed in the floor rock mass.

[0003] The commonly used engineering treatment method to prevent floor water inrush is to perform grouting transformation on the water source layer, transforming the aquifer into a relatively impermeable layer, and at the same time, the grouting slurry blocks the water channel to prevent the water from the floor aquifer from entering the coal mine shaft. The conventional application technology of the above grouting transformation method is the floor water hazard directional drilling regional treatment technology, which generally constructs directional branch drilling holes first, and then conducts high-pressure grouting treatment work after the holes are drilled. The key to the success of the grouting treatment work lies in the precise control of the directional drilling construction layer involved. When the aquifer to be treated for coal seam floor release is the Ordovician limestone (abbreviated as "Ordovician limestone") aquifer, its stratigraphic control needs to meet the following conditions: (1) the directional drilling branch should not enter the Ordovician limestone aquifer too deep, too shallow, or even out of the layer; (2) the directional horizontal main branch hole should enter within 10-15m below the top interface of the Ordovician limestone; (3) the undulation of the top interface of the Ordovician limestone should be clear; (4) in the event of displacement or displacement of the top interface of the Ordovician limestone when encountering faults, collapse columns or geological fracture zones, the trajectory of the directional horizontal hole should always be within 10-15m below the top interface of the Ordovician limestone.

[0004] In the prior art, the conventional methods for determining the stratigraphic interface are mainly geophysical exploration and drilling-while-drilling detection technology. However, the geophysical exploration method is an indirect method for exploring the stratigraphic interface, which interprets and infers the stratigraphic boundary and structural development through the difference in stratigraphic properties. However, drilling is still required for verification during the actual drilling process, that is, after the stratigraphic top interface is determined, the trajectory of the directional drill branch borehole is controlled. Therefore, the indirect exploration method has errors or is inconsistent with the stratigraphic sedimentary morphology, and abnormal situations such as layer breakout often occur. Although the drilling-while-drilling detection technology can realize the detection of stratigraphic boundaries, the detection range of this technology is only 3-6m, which cannot meet the detection requirements of 10-15m into the top interface of the Ordovician ash for water hazard area management. In addition, due to inaccurate data on the stratigraphic top interface, local layer breakouts often occur during directional drilling construction due to the fluctuations of the stratigraphic interface.
