Definitions
- the invention relates to a system and method for providing drilling fluid for earth boring, and to the use of a drilling fluid condition meter in providing drilling fluid for earth drilling.
- a drilling fluid When creating earth bores, and particularly horizontal bores, it is known to use a drilling fluid to assist in drilling boring.
- the drilling fluid can be used to soften the soil in front of the drill bit of the drilling apparatus and thereby improve the cutting action of the drill bit.
- the drilling fluid may serve to lubricate the drill bit and the drill string rotationally driven in the bore, and thus reduce friction with the soil.
- the soil degraded by the drill head can be flushed out through the annular gap between the drill pipe and the borehole wall or through an annular gap of a double drill pipe, which may have an inner pipe and an outer pipe.
- a drilling fluid is regularly a mixture of water and a mineral, in particular bentonite, and optionally some additives, which may also be mineral used.
- Bentonite is a mixture of different clay minerals, with the largest component being montmorillonite (usually 60% to 80%). Further accompanying minerals can be quartz, mica, feldspar, pyrite and sometimes also calcite. Due to the montmillonite content, bentonite has a strong water absorption and swelling capacity. Water, in which a mineral, in particular bentonite, is stirred, can exhibit a tixotropic behavior, so that this in motion can essentially behave like a liquid, but at rest essentially like a solid structure. Because of this property, a drilling fluid consisting of water and a mineral, especially bentonite, can also be used to support the borehole wall, so that collapse can be prevented.
- the drilling fluid is regularly mixed for storage and shipped to the site in large tanks, with regular use of tanks with a capacity of approximately 10,000 liters. Furthermore, it is known that the drilling fluid flushed out of the borehole is checked manually and processed by means of a separate recycling unit. A designated user must determine the condition of the drilling fluid and make adjustments to the recycling unit to re-drill the drilling fluid from the well.
- the disadvantage here is that due to different drilling conditions during a hole to be drilled, changes in the liquid coming out of the borehole can occur and the user entrusted with it is heavily bound in terms of time, constantly monitoring the condition of the drilling fluid and adjusting the recycling unit accordingly. As a result, the propulsion can be reduced or the time for the hole to be created can be increased.
- the core idea of the invention is to supply the drilling fluid coming from the borehole to a drilling fluid conditioner for determining the condition of the drilling fluid, in particular en route to the recycling device, and to provide a mixing device for mixing drilling fluid treated by the recycling device with liquid and / or mineral or minerals wherein the mixing device is coupled to the drilling fluid conditioner to perform the mixing depending on the condition of the drilling fluid.
- This may provide an automated and / or self-regulating system for providing drilling fluid for drilling, in which at least one measuring station is provided in the form of the drilling fluid condition meter, which is connected in the fluid path for the drilling fluid coming from the borehole in order to determine the condition of the drilling fluid.
- the coupling between the BohrroughkeitsWritsmesser and the mixing device can thus be done in particular without the intervention of a user.
- the coupling can be understood as a communication that can be unidirectional or bidirectional.
- the drilling fluid conditioner may transmit the condition determined by the drilling fluid to the mixing device by means of a signal sent to the mixing device, the mixing device in turn being able to send a signal to the drilling fluid conditioner to adjust the mixing fluid of the prepared drilling fluid with fluid and / or fluid To convey mineral or minerals.
- a user-made balance between the condition of the drilling fluid emerging from the borehole and a mixing device which performs the fluid and / or mineral or mineral drilling fluid used is not necessary.

It is possible to set a desired state for the drilling fluid, as it is to be used for drilling, ie as it enters the soil or the earth drilling device from the earth drilling device. By means of the core idea of the invention, however, not only is automation possible, but the constant monitoring of the drilling fluid can reduce the amount of pre-mixed drilling fluid.
