[0022] The surfactant is one of amino salt, amine salt or hydroxyl compound.

[0023] The crosslinking agent is silico...

Embodiment 2

[0025] It is processed by the following steps:

[0026] A, ingredients: take the following components according to the weight ratio: ultrafine basalt fiber, water, surfactant, polystyrene, polyhydroxyethyl acrylate, crosslinking agent;

[0027] B. Mixing: put ultra-fine basalt fiber, water, surfactant, polystyrene, and crosslinking agent in a reaction kettle, heat to 300-350°C after mixing, pressure is 1-1.5Mpa, and constant temperature is 8-15 hours ;

[0028] C. Drying: The temperature in the reaction kettle is lowered to 130-150°C, and spray-dried.

Embodiment 3

[0030] Basalt fiber is a new type of inorganic environmentally friendly green high-performance fiber material. It is composed of basalt rock materials composed of oxides such as silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, iron oxide and titanium dioxide. After melting at high temperature, it passes through the bushing plate quickly. drawn. Basalt continuous fiber not only has high strength, but also has various excellent properties such as electrical insulation, corrosion resistance, and high temperature resistance. In addition, the production process of basalt fiber determines that less waste is generated, less environmental pollution, and the product can be directly degraded in the environment after being discarded without any harm, so it is a veritable green and environmentally friendly material. my country has listed basalt fiber as one of the four major fibers (carbon fiber, aramid fiber, ultra-high molecular weight polyethylene, and basalt fiber) tha...

Abstract

The invention discloses a petroleum drilling auxiliary agent and a preparation method thereof, wherein the petroleum drilling auxiliary agent is mainly prepared from the following raw materials by ratio: ultra-fine basalt fibers, water, a surfactant, polystyrene, poly(hydroxyethyl acrylate), a crosslinking agent, and a phoebe zhennan powder. The petroleum drilling auxiliary agent is prepared by batching, mixing, drying and other steps. The petroleum auxiliary agent is prepared by using the basalt fibers, the production cost is reduced, moreover, the processing production is more environmentally friendly, the function effects of the petroleum auxiliary agent are also increased while the processing production is convenient, and the petroleum auxiliary agent has the advantages of good plugging effect on a variety of leakage of stratums, convenience in use, good compatibility, and no influence of slurry performance, and can improve the quality of mud cakes and reduce water loss. The main raw material basalt is volcanic rock, has widely distributed mineral resources in China and is easy to obtain and low in price, and thus the obtained product has high price / performance ratio.

Description

technical field [0001] The invention relates to a petroleum drilling auxiliary agent and a preparation method thereof, in particular to a petroleum drilling auxiliary agent made of basalt fiber and a preparation method thereof. Background technique [0002] In oil drilling operations, people in the industry often use bentonite and water to make drilling mud to facilitate the normal operation of drilling tools. In order to reduce the fluid loss of the drilling mud and the apparent viscosity of the drilling mud, the hydrolyzed polyacrylonitrile ammonium salt formed by the reaction of acrylic fiber and water is usually added as a drilling aid, which can significantly reduce the fluid loss of the drilling mud volume and apparent viscosity of the mud. [0003] At present, there are still some shortcomings in using hydrolyzed polyacrylonitrile ammonium salts as drilling aids. One is that the hydrolyzed polypropylene ammonium salt needs relatively high pressure in the production ...
