The application of shale shaker in non oilfield drilling is different with oil and gas drilling

The application of shale shaker develops fastest in the field of non excavation drilling. Many of the above types of vibrating screens together with hydrocyclones constitute drilling fluid cleaning equipment. The micro tunnel project of tunnel is widely used in Europe and is also increasingly used in the United States. Micro tunnel drilling is a kind of horizontal drilling with large borehole (from 27 to 10 feet), in which pipes are laid while drilling. This practice is most typical when laying or replacing water pipes and sewage pipes under urban buildings and traffic arteries.

In order to prepare for construction, large-diameter vertical boreholes or caissons shall be dug first, so that drilling equipment and hydraulic press can be installed at a certain depth. The open caisson is slightly lower than the equipment level, so a sedimentation tank can be formed when the drilling fluid returns, which is conducive to removing the solid phase. The drilling fluid pumped back to the surface is pumped into a simple solid phase removal system through a submersible pump, which is mainly composed of a vibrating screen and a drilling fluid cleaner installed on a small storage tank.



In order to lay pipelines on the river bottom for river crossing, it is necessary to drill a small-sized borehole on the riverbed. When the borehole with a larger diameter for laying the pipeline is used for back reaming, the pipeline is connected to the drilling tool and dragged back under the river. When laying large-sized pipes, a solid solid control system must be established with composite vibrating screen, desander, desilter, centrifuge, etc. The drilling fluid cleaning equipment reduces the waste of drilling fluid.
When laying pipes and cables across the road, it is often required to pass under the road. When drilling at the roadside, the traffic shall not be affected and the road surface shall not be damaged. This drilling size is usually small to avoid the use of solid phase removal equipment. If the drilling fluid accumulation causes impact, the drilling size is too large, a shale shaker or a drilling fluid cleaner will be used.
Fiber optic cable fiber optic cable laying does not need to drill a large borehole. However, since the construction is often carried out in residential and commercial areas, the drilling fluid and drilling solid phase must be loaded into special devices. At this time, the solid control system only includes a small storage tank, a pump box and a small shale shaker.
