Technical method adopting ultrasonic wave ceramic filter separating device for filtering drilling mud

Abstract

The invention provides a technical method adopting an ultrasonic wave ceramic filter separating device for filtering drilling mud. According to the technical method adopting the ultrasonic wave ceramic filter separating device for filtering the drilling mud, filtering equipment comprises a rack, a mud tank, a conveying table and a mud separating mechanism, wherein the mud separating mechanism is installed on the rack and communicated with the mud tank, the mud separating mechanism comprises a filtering chamber, a ceramic filtering plate, a vacuum mud collecting tank and a discharging mechanism, the ceramic filtering plate is located in the filtering chamber, the filtering chamber is installed on the rack through a rotor, in addition, the filtering chamber is communicated with the vacuum mud collecting tank through a flow guide pipe, and the vacuum mud collecting tank comprises a mud collecting tank body and a vacuum pump, the discharging mechanism is installed on the rack and abuts against the filtering chamber. The filtering technological method comprises the six steps including drilling mud collecting, first time filtration, second time filtration, filter cake stripping, filtering chamber cleaning and circulating filtration. The technical method adopting the ultrasonic wave ceramic filter separating device for filtering the drilling mud has the advantages that the structural design of the technical equipment is reasonable, the automation degree of the cleaning technology is high, and effective cleaning work can be conducted on the filtering equipment when mud filtration is conducted.

Description

technical field [0001] The invention relates to a process method for filtering drilling mud by using an ultrasonic ceramic filter separation device, which belongs to the technical field of drilling equipment. Background technique [0002] With the exploration and development of oil and natural gas resources, during the exploration process, the drilling rig removes a large amount of cuttings and waste liquid. These waste liquids not only contain a large amount of water and cuttings, but also contain a large amount of heavy metals and various inorganic salts. and macromolecular organic compounds, etc., leading to groundwater pollution, dust carrying sand and making the surrounding ecology vulnerable. Therefore, the drilling fluid must undergo necessary mud separation and other treatments to achieve harmless treatment before it can be discharged into the natural environment to avoid Cause serious environmental pollution around. In order to effectively separate the solid-liquid...

[0002] With the exploration and development of oil and natural gas resources, during the exploration process, the drilling rig removes a large amount of cuttings and waste liquid. These waste liquids not only contain a large amount of water and cuttings, but also contain a large amount of heavy metals and various inorganic salts. and macromolecular organic compounds, etc., leading to groundwater pollution, dust carrying sand and making the surrounding ecology vulnerable. Therefore, the drilling fluid must undergo necessary mud separation and other treatments to achieve harmless treatment before it can be discharged into the natural environment to avoid cause serious environmental pollution

In order to effectively separate the solid-liquid of the drilling fluid, the drilling fluid is mainly processed by using a large-scale slab ore filter press, which has the functions of screening and filtering at the same time. However, it is found in actual use that the current This type of equipment has a large volume and self-weight, and the intermittent working conditions lead to insufficient adaptability to the site, which cannot effectively meet the needs of various complex outdoor sites. At the same time, the degree of automation is low during operation, and the labor intensity of operators is extremely high. And the filtration quality is poor, and the operation energy consumption is relatively large. At the same time, it is necessary to frequently shut down the screening and filter components for maintenance or replacement, which also leads to poor operation stability of the equipment and high operation and maintenance costs. It is difficult to effectively meet the needs of drilling fluid cleaning operations, so in view of this situation, it is urgent to develop a new type of drilling mud separation device to meet the needs of actual use
