First, the use of products
FT-1 is a kind of anionic polymer, it is a kind of anionic polymer, its molecular structure is a C one C, one S C a key, key can be relatively strong, it is high temperature resistance. Because sulfonated asphalt contains sulfonic acid group, hydration is very strong, when the adsorption on the shale interface, can prevent the hydration of shale particles dispersed to play the role of anti collapse. At the same time, it is not soluble in water and can fill the pores and cracks, and can cover the shale interface, improve the quality of mud cake. The role of sulfonated asphalt in drilling fluid to lubricate and reduce the high temperature and high pressure filtration.
1 is a kind of plugging, anti collapse, lubrication, drag reduction, inhibition and other functions of the organic drilling fluid treatment agent;
2 drag reduction, reduce drilling tool lifting capacity and torque increase bit period, to prevent and release the drill;
3 to form a thin and tough mud cake to strengthen the wall. Control high temperature water loss;
4 control the high temperature shear strength of mud.  

Two, technical requirements
Table 1 Physical and chemical properties

 

Project	Index
Appearance	Song color particles or powder
Baking loss，%	≤10.0
Content of water soluble matter，%	≥70.0
Oil soluble matter content，%	≥25.0
Sodium sulfonate group content，%	≥10.0
HTHP Filtration loss，ml	≤25.0

Three, the use of methods
Can be used in combination with other mud treatment agent. Recommended dosage 1 ~ 3%.

Four, storage and transportation
1 products are stored in a dry and ventilated place, avoid direct sunlight and rain, away from fire.
2 transport and handling should be light light unloading, packaging to prevent breakage. Transport should be covered.

Five, matters needing attention
In the use of the process, the staff should wear a dust mask, wear chemical safety glasses, wear anti-static work clothes. Avoid producing dust. Prevent products from entering the eyes or in contact with the skin, once the occurrence of the above situation, with water or saline flush, the situation is serious and timely medical treatment.
