The application value of double-layer vibrating screen and three-layer vibrating screen in solid control of drilling mud: help to reduce equipment input and save equipment cost, realize energy saving; Further optimize drilling mud solid control layout, and improve drilling technology.
Double-layer vibrating screens and three-layer vibrating screens in the drilling mud solid control system have appeared for several years, but the popularity rate is still not high, because the cost of double-layer and three-layer vibrating screens is not as high as the single-layer vibrating screen, so most users will not choose multi-layer vibrating screen. That double-layer vibrating screen and three-layer vibrating screen in the drilling mud solid control is there any value? In fact, the application of double – and triple-layer vibrating screens is a more economical option than single-layer screens.
Double-deck vibrating screen
The traditional drilling rig mud solid control system is generally by mud vibrating screen mud cleaner
Centrifuge and other solid control equipment, and as a solid control equipment, the mud vibrating screen is generally composed of 2 or more single-layer specifications of the vibrating screen. The application of double-layer and three-layer mud vibrating screens is not simply to add several layers of screen mesh, but to fundamentally improve and upgrade the drilling mud solid control process. It is manifested in:
Compared with the traditional single-layer vibrating screen, the multi-layer vibrating screen has the characteristics of larger volume, larger exciting force, more screen mesh, larger screening area, larger processing capacity, etc., and these characteristics are reflected in the processing results, the accuracy of the multi-layer vibrating screen can reach the degree of integrated machine. In other words, the multi-layer vibrating screen can in some cases replace the traditional mud solid control system in the first solid control vibrating screen and two sand and mud removal machines.
Multilayer vibrating screen
Application value of double-layer vibrating screen and three-layer vibrating screen in solid control of drilling mud
First, the drilling mud solid control technology has been upgraded. The use of multi-layer vibrating screen means that the whole rig solid control system should be fully optimized and redesigned, and the traditional drilling solid control system layout and equipment arrangement must be changed, for example, the use of multi-layer screen, remove the traditional vibrating screen and sand descaler sand pump, etc., the volume and scale of the solid control system will be smaller, and the system will be redesigned to optimize the layout.
Second, reduce equipment investment to save equipment costs, less equipment less energy consumption, which achieved energy saving. The sand pump of the traditional solid control system mud and sand removal integrated machine has a power of 55KW/75KW each, and 2 sets work normally. The power consumption is 110 KWH per hour, 2200 KWH per day, 66,000 KWH per month, and 132,000 KWH per year. The vibrating screen power of the mud and sand removal machine is 3.88KW,
It consumes 3.88 KWH per hour, 77.6 KWH per day, 2328 KWH per month, and 4556 KWH per year. If the multi-layer shaker is used, about 136,656 KWH of electricity can be saved every year, which is equivalent to saving 21.45 tons of diesel and reducing emissions of 66.5 tons of carbon dioxide.
Therefore, the use of multi-layer vibrating screen is far lower than the use of traditional single-layer screen and multi-screen. In the future, with the improvement of the drilling process, the use value of double-layer and three-layer vibrating screens will be recognized by the industry and be applied and popularized in a wider range.
