Technology Placement of Drilling Waste Storage with the Use of Soil Cement Screens

Abstract

The authors of the article analyze the known technological solutions for the disposal of waste from drilling wells. The authors propose a technological solution for the arrangement of drilling waste storage from soil-cement elements with the installation of soil-cement coating. Filling the storage facility with waste is proposed to be carried out with layers of drilling mud, soil, ash. Used a layer of fly ash to reduce humidity, if it differs from the optimum. The thickness of the layers was chosen based on ensuring optimal humidity. The authors propose to add ash from the Mykolayiv thermal power plant in the amount of 5 wt.% By weight of cement when installing the walls and covering the sludge storage from soil cement. It is established that with increasing the shelf life of samples in water up to 180 days, the average compressive strength of soil cement samples increases. If we compare without additives and with the addition of the appropriate percentage of removal ash, the value of strength increases by 12-15%.
