Benefits of technology

The technical effect that this innovation improves how it works effectively for use at different depths within an underground borehole during drilling operations without causing contamination from wastewater produced along its way down through the ground surface. This results in improved production efficiency while also reducing environmental concerns associated therewith.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficiency and reliability of ground thermal resource use during oil exploration or other activities such as mineral extraction from underground sources like sands and coal deposits. Current methods involve either natural recovery through excavations or drilled boreholes with limited lifetimes caused by climate change (temperatures). Therefore, it becomes necessary to develop novel ways to recover these valuable materials without damaging our environments over time.

Abstract

The invention discloses a novel horizontal well terrestrial heat recharging method. The novel horizontal well terrestrial heat recharging method comprises the following steps that 1, selecting a terrestrial heat recharging research area with the proper temperature and flow; 2, establishing geothermal recharge numerical simulation models of two different well types by adopting numerical simulationsoftware; 3, performing comparative analysis, and proposing a proper recharging scheme; 4, implementing a recharge scheme, and comparing and analyzing data; and 5, according to data analysis, drawinga conclusion, in order to keep or improve the reservoir pressure and keep the high recharge rate and reservoir temperature, preferentially adopting a recharge scheme of different-layer horizontal wellrecharge vertical well mining with the well distance being 600 m and then adopting a vertical well different-layer one-recharge one-mining recharge scheme. The novel horizontal well terrestrial heatrecharging method is good in comprehensive utilization effect, pollution of terrestrial heat tail water to the environment is relieved, the reservoir pressure can be kept or increased, and the high recharging rate and the high reservoir temperature are kept.
