What is Geothermal drilling

Geothermal drilling is used for geothermal steam and hot water well drilling. It is a special technology and necessary method for the exploration, exploitation of geothermal fluid.

For the high temperature geothermal drilling, drilling depth is generally 500 meters to 2000 meters, a little more than 2000 meters, mostly in 600 ~ 900 meters. Regariding to the conduction type geothermal field at low temperature, the average depth is 1800 meters, while the geopressured geothermal drilling can reach to 6000 meters depth.

Features of mud recycling system for Geothermal drilling

1) As the temperature of Geothermal drilling is normally higher. There should be mud cooler before mud recycling system and after mud comes out from well head.

2) There should be galvanized grating to cover the tank tops for a better heat-radiation. Checkered plate is not recommended for Geothermal drilling mud recycling system. The heat cannot come out well in this condition.

3) Normally, there is only desander cone in the mud recyclone system. Desilter cone is not used.

4) As the mud temperature is higher, PU hydraocyclone is not suitable for Geothermal drilling mud recycling system, while cast iron cyclones should be used.

5) And in some cases, geothermal drilling rig platform is low, it means the flow height from drilling rig to shale shaker is lower. It gives strict limitation on shaker tank design.

GN Solids Control got an inquire from a European Geothermal drilling company. They are searching for a mud recycling system for their 750hp Geothermal drilling, and they want a 3-tank mud system.

After communication, we know that their flow height is only 2.6m. Per their condition, we offer tech. proposal together with commercial proposal, customer satisfy and give us order soon. And the system will be dispatch to jobsite soon.

Below is the system proposal we offered for the 750hp Geothermal drilling rig.

1) Shaker tank #1: 6012×2200×1600mm

2) Mixing tank 2# and Storage tank 3#: 11500×2200×2350mm

3) Shale shaker linear motion

4) Desander separate

5) Mixing system and mud agitators

As quickly as the drilling site has been chosen, scientists survey the region to figure out its boundaries, and conduct environmental effect studies if essential .Drilling firm may perhaps require lease agreements, titles and right-of way accesses before drilling the land. For off-shore sites, legal jurisdiction has to be determined.

Right after the legal challenges are solved, the crew goes about preparing the land:
1. The land have to be cleared and leveled, and access roads might be constructed.
2. Simply because water is utilized in drilling, there should be a supply of water nearby. If there isn’t any all-natural supply, the crew drills a water properly.

For drilling fluids and cutting disposal .The group digs a reserve pit, which can be applied to dispose of rock cuttings and drilling mud during the Drilling Mud System, and lines it with plastic to shield the environment. If the web page is an ecologically sensitive region, for example a marsh or wilderness, then the cuttings and mud must be disposed of offsite – trucked away instead of placed within a pit.
For that reason, deciding on a appropriate solids handle system is essential for the job web-site to prevent polluting the atmosphere. Firstly, we will need know how several shale shaker might be applied for the job internet site and relative mud cleaner ( for separating the fine particle. Secondly, the solids and cutting from shale shaker and mud cleaner are transferred by GN screw conveyer (auger) to the site for truck to delivery offsite or do additional course of action. Thirdly, GN decanter centrifuge is focused on separating the fine particle beneath 20 microns, which sustain the drilling fluids weight and retain drilling fluids clean. Finally, the drilling cuttings from shaker and drilling mud system still include fluids, which contaminate the soil if they’re directly buried. Consequently, GN-Solids-America vertical USA cutting dryer can dry drilling cutting to reduce the contamination and reclaim the drilling fluids.

All in all, deciding on a fantastic solids control technique is an critical portion for drilling. You could seek advice from with GN for solids handle unit.
