Collection method of saline bearing brine reservoir brine and solid salts

Abstract

The invention belongs to the technical field of salt lake resource exploitation, and in particular relates to a method for collecting brine and solid salts in a pressurized brine storage layer of a salt lake. The method is to use a non-excavation engineering drilling rig to construct and arrange solvent flower tubes inclined into the pressure-bearing brine storage layer, then input solvent from the upper end of the solvent flower tube into the pressure-bearing brine storage layer, and then incline into the pressure-bearing brine storage layer The construction arranges the suction flower tube, and the brine and dissolved solid salts in the pressurized brine storage layer are transported to the ground through the suction flower tube. According to preliminary estimates, this method can save more than 50% of infrastructure investment, more than 33% of operating and maintenance costs for brine mining and transportation, and increase the amount of brine and solid salt resources by about 1 to 5 times, making the "stupid" Mine" has become a live mine, which has great economic and social benefits.

Description

1. Technical field: [0001] The invention belongs to the technical field of salt lake resource exploitation, and in particular relates to a method for mining brine and solid salts in a pressure brine storage layer of a salt lake. 2. Background technology: [0002] At present, in the exploitation of modern salt lake resources, only rich ore brine and solid salts located in the shallow surface can be mined. The method of mining rich ore brine is direct suction, while solid salts are directly excavated or dissolved in fresh water. The method of pumping brine is used for mining. However, these resources located on the shallow surface are limited, usually only accounting for 1 / 10 to 3 / 10 of the total resources of the salt lake. The mining and utilization of human resources is a technical problem that people urgently need to solve. However, the geological age of the formation of the pressurized brine storage layer is a little longer, and it has experienced geological structure ch...

Problems solved by technology

The traditional mining method is to adopt the mining scheme of drilling-pumping-pipeline transportation. This scheme requires the construction of a large number of brine mining wells to increase the cost of brine mining for mine layers with small porosity and water supply, and there will be The problem of salt accumulation in the well pipe, and because of the high specificity and viscosity of brine, the recovery rate of brine is lower
