Brine mining well structure for slattern geology containing multiple drift sand layers

Abstract

The invention relates to the technical field of brine mining in salterns and discloses a brine mining well structure for slattern geology containing multiple drift sand layers. The brine mining well structure comprises a well body. A filter steel cylinder is arranged in the well body, and the height of the filter steel cylinder is the same as the depth of the well body; the bottom of the well bodysupports the filter steel cylinder; and filter holes are formed in the cylinder wall of the filter steel cylinder. The structure is simple and reasonable, the construction problems such as well collapse and pump burying can be prevented effectively, drift sand of the drift sand layers is filtered effectively, the well washing efficiency is promoted, and thus the well-forming process is rapid andsmooth.

Description

technical field [0001] The invention relates to the technical field of brine mining from salt fields, in particular to a brine mining well structure used for the geology of salt fields containing multi-layer quicksand layers, especially suitable for areas containing multiple layers of thick quicksand layers in the geological structure. Background technique [0002] Brine mining is one of the commonly used techniques for deep brine mining in salt fields. The traditional method is to use rotary drilling to drill wells, and then lower the brine pump to the bottom of the well to start pumping water to wash the well. After cleaning the impurities such as quicksand in the brine, the salt field brine is extracted. However, in the case of multi-layer thick quicksand layers in the geological structure of the salt field, the quicksand in the quicksand layer is continuously extracted with the brine after the well is completed, and the quicksand flows back continuously, resulting in a lo...

AI Technical Summary

Problems solved by technology

However, in the case of multiple layers of thick quicksand layers in the geological structure of the salt field, the quicksand in the quicksand layer will continue to flow back with the continuous extraction of brine after the well is completed, resulting in a long cleaning process and difficult to clean. , the well cannot be completed in time, and at the same time, when the quicksand layer is too thick, it is easy to cause construction problems such as well collapse and buried pump, resulting in difficulty in well completion
