Multi-well micro-metering well investigation method for ultra-thick loess highland

The invention provides a multi-well micro-metering well investigation method for the ultra-thick loess highland. The method comprises the steps that 1, motivating factors of a motivation well are designed in a sub-order mode in combination with the motivation depths and conventional micro-metering wells; 2, multiple receiving wells are distributed around the motivation well; 3, channel drawing, wavelet and amplitude analysis are carried out on investigation records of multi-well micro-metering wells to obtain the investigation records and amplitude data information of the different depths; 4, investigation results of the motivation well and the receiving wells are explained in a unified mode to obtain a near-surface structure speed and depth relation model, and amplitude change conditions of the different depths are combined to obtain a near-surface absorptive attenuator tendency chart. According to the multi-well micro-metering well investigation method for the ultra-thick loess highland, the near-surface structure and an absorptive attenuator law can be checked out, the defect of near-surface understanding of similar areas is made up, and the method is an effective method for investigating the near-surface absorptive attenuator law, and has high application and popularization value in the whole loess highland.
