General introduction of Geothermal well
Geothermal wells are wells which tap into the natural geothermal energy found beneath the Earth’s crust. There are a number of different types which can be utilized in various ways, ranging from wells which connect to sources of steam which can be used to power turbines to wells utilized in geothermal heat pumps, which maintain stable indoor temperatures with the use of a recirculating water system. Most of the world’s geothermal wells are found in areas of increased geological activity.
Features of Geothermal well
Like other types of wells, geothermal wells are created by drilling into the Earth’s surface and then sinking in well rings to keep the hole from collapsing. Production wells are geothermal wells which connect to sources of geothermal energy, while injection wells are designed to force water underground for the purpose of maintaining a steady supply of water in the geothermal system.
Some geothermal drillers use AIR drilling for Geothermal but they will have to use drilling mud when we encounter water and the air won’t lift the water anymore. Then drillers will have requirement for mud recycling and solids control.
Geothermal well drilling mud system
Usually geothermal well drilling depth is not so deep as oil/gas drilling well, so they do not need very large treating capacity, but there is strict requirement to separate fine particles from the drilling mud, just like workover drilling rig mud system. For example, clients will need a decanter centrifuge in a workover mud system to keep the balance of the drilling mud.
Similar with oil/gas drilling mud solids control system, geothermal well drilling also need a vacuum degasser to process the invade mud. So usually you need to adopt the following equipments:
1 two sets of shale shaker
3 decanting centrifuge( middle speed or high speed, depends on client’s requirement)
4 Mud mixing unit ( hopper and pump)
6 Mud gun
7 Mud tank
