Embodiment Construction

[0024] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0025] Such as figure 1 , figure 2 and image 3 As shown, the mine monitoring equipment according to the embodiment of the present invention includes: a pump 20 for driving drilling fluid or fracturing fluid containing fluorescent powder into the underground of the mine, and the pump 20 is connected to the mine, such as being set at the wellhead; detecting fluorescence Powder spectrophotometer 30, connected with the mine. The spectrophotometer 30 is set outside the mine, for example, at the head of the well, so as to detect in time. When drilling or fracturing, the fluorescent powder is driven into the underground. During production, the mine is drained and depressurized, and the water discharged from the mine to the ground i...

Abstract

The invention provides a mine monitoring method and mine monitoring equipment. The mine monitoring equipment comprises: a pump for injecting a drilling fluid or a fracturing fluid containing fluorescent powder into the mine, and a spectrophotometer for detecting the fluorescent powder, wherein the pump is connected with the mine; and the spectrophotometer is connected with the mine. The mine monitoring method comprises at least the following steps of: injecting the drilling fluid or the fracturing fluid containing the fluorescent powder into the mine; draining off water of the mine to reduce the pressure; detecting the fluorescent powder of the water discharged from the mine to the ground; and judging the effectiveness of the drilling and fracturing processes according to a detection result. According to the mine monitoring equipment and the mine monitoring method, the effectiveness of the drilling and fracturing processes can be judged.

Description

technical field [0001] The invention relates to the field of drilling, in particular to a mine monitoring method and equipment, in particular to a monitoring method and equipment for coalbed methane multi-branch horizontal well drilling and vertical well fracturing. Background technique [0002] As my country's coalbed methane enters the commercial development stage, in order to pursue high efficiency, developers begin to drill more and more lateral wells. The total footage of a single well has reached more than 4,000 meters, and some even reached more than 8,000 meters. There are also various types of branches, including double branches and multi-branches. There are as many as 10 branches in one well. After the drilling project is completed, the well is usually completed with open holes, and there are also examples of well completion with plastic pipes. At present, horizontal staged fracturing is still being tested, and then the production process of drainage and gas recov...
