In the field of oilfield exploitation, the problem of erosion and wear of screw pumps caused by sand containing crude oil is prominent. When expanding, supplement the working principle and wear hazards of screw pumps, details of Daokedao equipment processes, and specific oilfield data generation processes to enhance the richness and persuasiveness of the content.
In oil field exploitation, screw pumps have become one of the core equipment for oil extraction operations due to their high efficiency and stability. Its working principle is to form a sealed chamber through the mutual meshing of the screw rotor and stator, and continuously move it to transport crude oil from the bottom of the well to the surface. However, when extracting crude oil containing sand, the screw of the screw pump rubs against the crude oil carrying sand and gravel at high speed for a long time. The sand and gravel act like countless small "sandpapers", continuously eroding and wearing the surface of the screw, resulting in material peeling and decreased dimensional accuracy, which in turn affects oil extraction efficiency and increases equipment maintenance costs.
Daokedao's automated laser cladding equipment has customized a tungsten based alloy coating solution for screws to address this challenge. This technology utilizes a high-energy density laser beam to instantly melt and fuse tungsten based alloy powder with the surface of the screw substrate, forming a dense and firmly bonded alloy coating. Tungsten based alloys have high hardness, strong wear resistance, and good corrosion resistance, which can effectively resist the erosion of sand containing crude oil. After testing by a professional testing agency, the screw treated with Daokedao laser cladding technology has three times the erosion resistance of ordinary screws, greatly improving the service life of the screw under harsh working conditions.
In the practical application of a large oil field, three representative oil wells were selected for testing. These three oil wells were previously plagued by frequent screw wear issues, resulting in low oil recovery efficiency. After using the Daokedao laser cladding treatment on the screw, the effect is immediately apparent. The single well oil production cycle has been significantly extended from the original 45 days to 130 days, effectively reducing downtime caused by equipment failures; The number of well repairs has decreased by 67%, significantly reducing manual maintenance costs and operational risks. What is even more surprising is that after a year of operation statistics, the annual increase in crude oil production of a single well is about 80 tons, and the cumulative increase in production of three oil wells is 240 tons, bringing considerable economic benefits to the oilfield and fully demonstrating the strong application value of Daokedao's automated laser cladding equipment in the oilfield field.
