Description

Technical Field

[0001] The utility model relates to the technical field of drilling, in particular to a drilling mud solid-liquid separation device. Background Art

[0002] The work of drilling holes in the ground using mechanical equipment or manpower is called drilling. It usually refers to the engineering of drilling wells and large-diameter water supply wells for the exploration or development of liquid and gaseous minerals such as oil and natural gas. Drilling is widely used in national economic construction. Rotary drilling is widely used in oil (gas) fields in my country. The main equipment includes derricks, operating platforms, diesel engines, drilling rigs, drilling tools, mud pumps, generators and testing equipment, as well as fuel tanks, boilers, etc. The diameter and depth of the drilling depend on the purpose of the drilling and the burial depth of the minerals. The drilling diameter for drilling oil, natural gas and groundwater is relatively large. Drilling mud is a general term for various circulating fluids that meet the needs of drilling work with their multiple functions during the drilling process. Mud is a widely used drilling fluid, mainly suitable for loose, fractured, easy to collapse and fall off, and water-expanded and peeling rock formations with unstable pore walls.

[0003] A Chinese patent with the publication number CN213610103U disclosed a solid-liquid separation device for oilfield drilling mud, including a main shell, legs are fixed at the four corners of the bottom of the main shell, a water outlet pipe is connected to the bottom of the main shell, a lower ring plate is fixed on the top of the main shell, an upper shell is placed on the top of the main shell, an upper ring plate is fixed on the top of the main shell, and the upper ring plate is placed on the top of the lower ring plate, a plurality of limiting holes are opened on the lower ring plate, a plurality of limiting rods are fixed below the upper ring plate, and one end of the limiting rod passes through the limiting hole and extends downward, a frame is installed below the main shell, a filter screen is fixed in the frame, and an inner shell is fixed in the main shell. The solid-liquid separation device can separate the mud into solid and liquid by pouring the mud to be separated into the upper shell and passing through the filter screen.

[0004] This oilfield drilling mud solid-liquid separation device adopts a soft-bristled brush to rotate and clean the mesh of the filter to avoid clogging of the filter. However, this method can only be performed after the filter separates the solid and liquid of the mud. During the process of the filter separating the solid and liquid of the mud, clogging will still occur, which will seriously affect the work efficiency. Utility Model Content
