API standard—drilling mud bentonite
SAPI-1
We can supply all kinds of high quality drilling bentonites:
API Bentonite,OCMA Bentonite,Drilling Bentonite
1.Introduction:
Drilling bentonite has the great expansibility under water, has the good colloid properties and can heighten the suspension of liquid viscosity.As a result,in drilling mud,bentonite can increase the drilling tools lubricity, Cleaning produces in the process of drilling cuttings, be widely used to complex geological structure formation drilling construction, to prevent hole accidents.
The products are known for its good performance, strong water hydration expansion,big cation exchange capacity and high made pulp rate
2.Specification:

The mentioned data of analysis just for reference, the actual result depends on physical material loaded.
3.Application:
Bentonite has a big expansion after meets water, has a good colloidal nature, can increase the viscosity of suspension in the drilling mud when used, can increase the lubrication of drilling, cleaning the debris during drilling, as well as for the rig-freeing agent. So which is widely used in complex geological formation drilling
To be suitable for lower solid mud, has clear action on stop falling anything from caving and stop up leak,it has good close water base of interchangeability, thixotropy, lubrication, dilatancy, suspension property and similar to white powder, it is also or be used for oil and gas well drilling and civil-engineering include applied drilling fluid system for horizontal directional drilling , applied fluid solutions for diaphragm walls and piles, lubrication fluids for micro tunneling or pipe jacking, drilling fluids for water well, exploration and mining, fluids solution for shield tunneling.
4.Our advantages:
Our drilling with sodium bentonite strict implementation of the Chinese National Standards and the United States API grade: has a good suspension, thixotropy and filtration a small amount of mud performance is good, the preparation of convenient, easy to adjust the drilling fluid weight and other characteristics, is essential for deep and ocean drilling an ideal base material.
