First, the use of products
Well leakage is a common well in drilling engineering, and most of the drilling processes have different degrees of leakage. Serious leakage can cause the pressure drop in the well, affect the normal drilling, wellbore instability, induced formation fluid into the wellbore and blowout.
After the product is added in the drilling, under the pressure difference function, the formation can be well sealed, the use is convenient, the compatibility is good, and the performance of the slurry is not affected.

Two, technical requirements

 

Project		Index
		一 level	二 level	三 level
Appearance		White powder
Shale moisture，%		≤15
Granularity	0.45mm residue	≥80	≥70	≥60
	3.0 mm residue			<10
	5 mm residue		<5
	7 mm residue	<5

Three, the use of methods
According to the actual situation of the site.

Four, storage and transportation
1 products are stored in a dry and ventilated place, avoid direct sunlight and rain.
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 masks, 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.
