Abstract
The invention discloses seawater proportioning powder, which belongs to the field of chemical engineering. The seawater proportioning powder disclosed by the invention comprises the following compositions: 40-66% of soil powder, 10-15% of attapulgite, 5-10% of polyanionic cellulose, 3-5% of biopolymers, 3-5% of hydroxyethyl cellulose, 3-5% of sodium carbonate, and 10-20% of sepiolite. According to the invention, the water utilization problem for proportioning on the sea can be fundamentally solved, thereby reducing the transportation cost of fresh water proportioning, reducing the labor intensity of workers, and reducing the technical difficulty of proportioning.
Description
Technical field
The present invention relates to seawater prepared bentonite drilling fluid powder, belong to chemical field.
Background technology
At present, along with the exploitation in ocean and sea, beach, the difficulty of preparation drilling fluid strengthens, the salinity of seawater is high, use the common native powder can not be with slurry, but, outstanding that fresh water On Computation for Drawing Water becomes used, construction area does not have fresh water to use around, draw the cost of water too high with tank car, once weather changes, leakage occurs, if fresh water is not supplied, consequence can be very serious.
Summary of the invention
For above-mentioned deficiency, the invention provides seawater prepared bentonite drilling fluid powder.
The present invention is achieved by the following technical solutions: seawater prepared bentonite drilling fluid powder, and composition of the present invention is by as follows than reshuffling:
Soil powder: 40%～66%, attapulgite: 10%～15%, Polyanionic Cellulose: 5%～10%, biological polymer: 3%～5%, Natvosol: 3%～5%, sodium carbonate: 3%～5%, sepiolite: 10%～20%.
Preparation method of the present invention is as follows:
Under normal temperature and pressure, according to the important interpolation component of asking of ratio of component of invention, various components are mixed, stirred.
Using method of the present invention is as follows:
Powder with slurry is joined in seawater.
The usefulness of this invention is: can fundamentally solve marine problem of water consumption with slurry, reduce fresh water transportation cost with slurry, reduce workman's labour intensity, meanwhile, reduce technical difficulty with slurry.
