Abstract

A preparation method for a heatproof salt-resistant well-drilling slurry processing agent is characterized in that: the agent is composed of in parts by weight: 15-30 parts of clay, 30-50 parts of sodium chloride, 2-10 parts of calcium chloride, 2-10 parts of magnesium chloride, 2-5 parts of starch, 2-10 parts of carboxymethylcellulose sodium, 1-5 parts of phenol, 1-5 parts of sulfur, 3-9 parts of borax and 50-80 parts of water; and the product is prepared by mixing all of the raw materials , stirring uniformly and reacting at 180-190 DEG C for 60-120 min. The product has the advantages of being easily available in raw material, low in cost, green, environment-friendly, convenient to use and good in effect.

Description

technical field [0001] The invention belongs to an oilfield chemical. Background technique [0002] Oilfield chemicals, in a broad sense, refer to various light chemicals used in all processes such as oil exploration, drilling, gathering and transportation, mainly including mineral products (such as soil removal, etc.), general chemicals (such as various Acids and alkalis, etc.), natural products (such as starch), inorganic products (such as zinc carbonate) and special (fine chemical) products (such as polymers and surfactants, etc.). Oilfield chemicals refer to a class of additives used in the drilling, production and transportation of oil and natural gas, water quality treatment and enhanced recovery. It has a wide variety, most of which are water-soluble polymers (such as vegetable gum, polypropylene amides, cellulose and biopolymers) and surfactants (petroleum sulfonates, alcohol or alkylphenol ethoxylates). The content of oilfield chemistry research is mainly the prep...
