Abstract

The invention provides a method and device for finely depicting underground karst structures. Including: divide the water well into two groups of observation wells and pumping wells, establish a time flow rate algorithm, obtain the data to be calculated, calculate according to the time flow rate algorithm, obtain the flow rate value, pump the pumping well according to the flow rate value, and record the water level in all the wells Change data; set the comparison value threshold, determine and obtain the value to be compared according to the water level change value of the observation well and the water level change value of the pumping well, compare the comparison value threshold with the value to be compared, and describe the underground karst structure according to the comparison result. In the present invention, by setting the pumping flow rate of the pumping well as a cosine function with time as an independent variable, the water level change value in the observation well is analyzed, and combined with the water level change value (phase and amplitude) in the pumping well, the underground karst structure can be accurately and quickly described finely .

Description

technical field [0001] The invention relates to the technical field of depicting underground karst structures, in particular to a method and device for finely depicting underground karst structures. Background technique [0002] For many years, scholars at home and abroad have devoted themselves to the research of karst structure depiction technology, which is widely used in water resources development and protection, oil exploitation, geothermal energy development and other fields. The interwell pumping test method is one of the formation parameter characterization techniques. The so-called cross-well pumping test technology refers to the target area, pumping a certain amount of water from the pumping well and measuring the change of the water level in the well at a certain distance from the observation well at different times, and using various groundwater flow theoretical formulas or graphical methods to analyze the pumping test. The method of obtaining formation paramet...
