Organophilic clay composition | For Oil Drilling Mud

Organophilic clay composition: Organic bentonite used in oil-based slurries may be of particular interest to users but need to pay attention to the topic, the following are some summarized:

First, the role and characteristics of organic bentonite

1. viscosity and cut: organic bentonite as a thickener and suspending agent for oil-based mud, can significantly improve the viscosity and cut of the mud, which contributes to the stability of the drilling process and carry, as well as thixotropy.
2. Lubrication and anti-corrosion: It can effectively lubricate the drilling well and reduce the friction resistance, as well as prevent the corrosion of drilling equipments and tubing columns, and moreover avoid the collapse of the oil well.
3. rheology and carry: bentonite can improve the rheology of the mud, making it easier to pump and carry drill cuttings, effectively cleaning the borehole.

Second, the use of organic bentonite in oil-based mud precautions

1. moderate use: we recommend that you use organic bentonite in large quantities to the mud, the first sample test, the amount of use according to the experimental results to determine. Because excessive use may affect the performance of the mud, such as causing the mud is too thick, increase the difficulty of pumping.
2. Stirring and mixing: bentonite should be fully stirred and mixed with the oil-based slurry to ensure uniform dispersion, in order to improve its effectiveness. High-speed mixing time should not be less than the specified time to ensure that the bentonite performance is given full play.
3. Add activator: We recommend that you use the right amount of activator, such as methanol ethanol, propylene carbonate, when using organic bentonite to oil-based slurry.In some experiments, water is also a good activator.
4. When using organobentonite in oil-based slurries, the order in which the different chemical additives and fillers are used is also critical.Because if other chemical additives are added to the formula at the same time, there is a risk of weakening the active ability of the bentonite itself. 5.
5. in the storage of organic bentonite, must also be placed in a dry and ventilated and avoid strong light place, avoid sun and rain or too high temperature environment, the organic bentonite must be sealed after opening to avoid affecting its own quality.
6. In the use of organic bentonite, we recommend that experimental personnel or production personnel, with protective masks and protective gloves, safety operations.Avoid inhaling the dust into the body. 7.
7. Different drilling conditions, organic bentonite in the use of the time, it is ultimately different ability to fake, so we have to drill according to the environment, such as deep sea wells, according to the depth of the well temperature and stratigraphy, etc. Adjustment of the formula, but also includes the adjustment of its use.
8. At present, the dispersion and suspension of sodium bentonite is more suitable for use in oil-based mud, so not all bentonite is suitable for drilling fluids.
9. Not the more you add, organic bentonite can improve the performance of the mud. In some cases, if the amount is too much will cause the difficulty of pumping, because the mud is too thick, so that it can not be properly transported.
10. not all chemical additives & Organophilic clay composition will have compatibility with organic bentonite, so we must carry out sample tests to ensure that it is compatible with the overall formulation.  
11. we must ensure that the organic bentonite in the oil-based mud fully dispersed and dissolved, otherwise it will directly affect the stability of your performance, and ultimately affect the effectiveness of drilling, so we must use high-speed stirring and mixing measures to ensure that the organic bentonite in the mud fluid fully dissolved and dispersed.

Organophilic clay composition:

CP-250A Organophilic Clay is an easy dispersing, self-activating organoclay that exhibits high performance efficiency in diesel, low aromatic mineral oil, modified vegetable oil and synthetic base fluid formulation. CP-250Aunique rheological structure suspends weighting materials and other solids with less increase in viscosity and gel strength than conventional bentonite. It is highly effective in distillate and mineral oil-based invert fluids.
