Abstract
The invention relates to a granular graphite treating agent for drilling fluid, a preparation method and application thereof. The granular drilling fluid treating agent is prepared with graphite or graphite powder, and optionally chemical assistant and forming agent as material. The preparation method comprises the following steps: the raw materials are mixed, and are granulated by a manual granulating or a granulating machine, and are dried to prepare the granular treating agent. The application is as follows: the granular treating agent is prepared with water soluble forming agent or oil soluble forming agent to form water aqua treating agent or oil treating agent for graphite. The invention makes graphite powder into particles or colloid suspension with dispersibility by granulating or preparing the graphite powder, so as to adjust the physical and chemical properties of graphite, reduce dust and eliminate precipitation.
Description
The present invention relates to materials such as a kind of employing Graphite Powder 99,, form product and be used for additive for drilling fluid, the preparation method and its usage of drilling fluid as treatment agent by preparation processing or granulation processing.
Graphite has excellent lubrication and chemical stability.But because the easy dirty person of its dust and environment, and its physicochemical property is difficult in and suspends in the solution, often just occurs deposited phenomenon when static, and this prong material fails to obtain extensive studies and utilization at home and abroad the field of oil drilling so far for this reason.
The object of the present invention is to provide additive for drilling fluid, preparation method and the goods thereof of the preparation of a kind of using mineral carbon powder, make it not have the dirty person of dust, preparation does not have sedimentation phenomenon to take place.
The present invention is achieved in that
A kind of granular graphite processing agent that is used for drilling fluid, it is to use graphite or Graphite Powder 99, add or do not add chemical assistant, forming agent is a raw material, makes the particulate state additive for drilling fluid.
Above-mentioned chemical assistant is meant polyoxyethylene glycol, molybdenumdisulphide, tetrafluoroethylene or other drilling fluid materials, and its proportioning accounts for 20～70% (by weight percentage) of whole granulated material.
Above-mentioned forming agent is meant materials such as carboxymethyl starch, carboxymethyl cellulose, polysaccharide, and its proportioning accounts for 2～5% (by weight percentage) of whole granulated material.
A kind of preparation method who is used for the granular graphite processing agent of drilling fluid is characterized in the raw material process is mixed, and adopts manual granulation or tablets press granulation, and the particulate state treatment agent is made in oven dry.
A kind of purposes that is used for the granular graphite processing agent of drilling fluid is characterized in:
A, the particulate state treatment agent made from water-soluble forming agent, the aqua treatment agent of graphite;
B, the particulate state treatment agent made from the oil soluble binder, the finish treatment agent of graphite.
The carboxymethyl starch glue that above-mentioned water-soluble binder is 2～5% concentration or other colloidal solutions.
Oil solutions such as white oil that above-mentioned oil soluble binder is 2～3% organophilic clays or oil-soluble resin or diesel oil.
Compared with prior art, the present invention becomes it and has dispersed particle or soliquid by with Graphite Powder 99 granulation or preparation; with physico-chemical property and the minimizing dust of regulating graphite; eliminate sedimentation phenomenon, make it can be adapted at using in the drilling fluid field, the Application Areas of developing Graphite Powder 99.The proposition of present method will provide an operating environment of eliminating dust for the work of treatment of drilling fluid, also will change the prior art of drilling fluid, from an application of the physicochemical property of attention research additive for drilling fluid material self, free, utilize comprehensive preparation and agglomeration technique, simple host utilisation technology of past is become the Application of composite technology of host and assistant agent, the additive for drilling fluid of Development of New Generation improves and handles quality and treatment technology.
The current producible product of this invention is:
(1) mud solid phase treatment agent: with Graphite Powder 99 is major ingredient; polyoxyethylene glycol, molybdenumdisulphide and tetrafluoroethylene are auxiliary material; tensio-active agent (alkyl sodium sulfonate, clean-out system Magco-D.D) is an auxiliary agent, and activation is two hours under 80 ℃ of conditions; then with carboxymethyl starch or other macromolecular compounds as forming agent; adopt manual granulation or tablets press granulation, make the particulate state treatment agent, its proportioning is (weight ratio): major ingredient 60, auxiliary material 40; auxiliary agent 5～8, forming agent 2～3.Particle diameter can be processed adjusting as required, and general diameter is 1～10mm.
(2) drilling fluid is with graphite colloid treatment agent: this agent divides aqua and finish two classes, it all is major ingredient with the Graphite Powder 99, make the FEOL of suspension and the technology identical (promptly adding host, assistant agent and auxiliary agent postactivated two hours) of granulation by proportioning, the activatory material is put in the carboxymethyl starch glue or other colloidal solutions of 3% concentration, the aqua treatment agent of graphite; Put in the oil solutions such as white oil or diesel oil, become the finish treatment agent, in oil product, must add 2～3% organophilic clay or oil-soluble resin, can keep the suspension stability of graphite in oil product.
