Drilling rock harmless treatment and resource utilization technology and device

Abstract

The invention discloses a drilling rock harmless treatment and resource utilization technology and device. The drilling rock harmless treatment and resource utilization technology includes the steps: a taking step: extracting preset-volume to-be-treated rock debris in a rock debris storage pool, and taking the volume of the preset-volume to-be-treated rock debris extracted at each time as a volume unit; a crushing step: crushing the to-be-treated rock debris taken in the taking step into powder particles; a curing step: respectively adding the preset volume parts of a curing agent, cement and stones into the powder to-be-treated rock debris, and blending evenly into a mixture; and a forming step: pressing the mixture formed in the curing step into preset-volume building blocks. In the way, a solid component after solid-liquid separation forms the mixture through the technology and through the action of the preset-proportion curing agent and other raw materials, the mixture is pressed into the building blocks, and the transformation of solid slurry into a building material is achieved; the technology has strong curing treatment ability, and the resource utilization degree and the environmental protection performance are improved.

Description

technical field [0001] The invention relates to the technical field of drilling assistance, in particular to a process for harmless treatment and resource utilization of drilling rock. The invention also relates to a device based on the above process. Background technique [0002] Drilling fluid is a circulating fluid used for drilling, and it is a circulating flushing medium used in the hole during the drilling process. Drilling fluid has the functions of carrying and suspending cuttings in the wellbore, balancing formation pressure, cooling and lubricating drill bits and drilling tools, protecting well walls and oil and gas layers, and increasing drilling speed. It plays a very important role in the drilling process. [0003] Drilling waste fluid (mud) is a multiphase stable colloidal suspension system, containing various inorganic salts, organic treatment agents, polymers, surfactants and other substances, which contain oils, salts, drilling fluid additives and some solu...

AI Technical Summary

Problems solved by technology

[0004] The traditional harmless treatment and resource utilization technology of drilling rock can only realize simple filtration and solid-liquid separation of mud above the drilling platform, and the processing capacity is low, and the solid phase components produced by the treatment are piled up in the well site, occupying the well Field space, and the reuse of solid phase components cannot be realized
