Complete oil fracturing sand production line
Oil fracturing sand has high compressive strength and is mainly used for downhole support in oil fields to increase oil and natural gas production, and is an environmentally friendly product. The product has the advantages of high compressive strength, low density, good sphericity, high smoothness and strong flow conductivity.
The specifications of petroleum fracturing sand products are: 20-40 mesh, 40-70 mesh, 70-140 mesh. In the field of petroleum, fracturing refers to a method of using hydraulic action to form cracks in oil and gas layers during the process of oil or gas production, also known as hydraulic fracturing.
The overall fracturing sand production line is divided into five working stages, namely the raw material mining stage, the raw material drying and pre-screening stage, the raw material washing stage, and the concentrate drying stage. It can solve the problems of fracturing sand classification, washing, tail water purification, solid waste dry discharge, etc. The finished product can achieve round sand particle size and higher compression value. The entire production line has large output, high efficiency, stable operation, and equipment can be configured according to customer conditions.
Working principle
The raw sand of fracturing sand enters the silo for storage, and is sent to the vibrating screen or probability screen for preliminary screening through the belt conveyor. <20 meshes are magnetically separated by a magnetic separator, and then enter the scrubbing machine. When the materials pass through, they are fully stirred and washed. After scrubbing off the mud, they enter the sand washing and recycling integrated machine. , which can remove the impurities covering the surface of the material. After cleaning, the coarse-grained material is sent to the dewatering screen by the sand fishing wheel for dehydration. The granular material after sand washing is dried by the dryer, and the material to be dried slips into the cylinder from the feeding box and the feeding material, so as to achieve the purpose of drying. The dried materials are screened by a swing screen, and the screening accuracy can reach 90-95%. The qualified fracturing sand is packaged and shipped out.
The tail water treated by the separator of the integrated sand washing machine enters the sewage transfer tank, and then the tail water is pumped from the sewage tank into the trihydrogen purification body by the pump for mud-water separation operation. The concentrated mud is pumped into the plate and frame filter press through the bottom of the filter tank to achieve dry stacking. After pressure filtration, the clean water enters the clean water tank to realize the recycling of clean water.
