Abstract
The invention discloses an inhibiting and anti-sloughing agent for drilling fluid and aims to provide the inhibiting and anti-sloughing agent for the drilling fluid having good use effects in various fluid environments. The technical scheme of the invention is that the inhibiting and anti-sloughing agent for the drilling fluid comprises the following components in part by weight: 450 to 650 parts of acrylamide monomer, 50 to 250 parts of acrylic acid, 100 parts of potassium carbonate or potassium hydroxide, 50 parts of sodium hydroxide, 50 parts of ammonia, 100 parts of dimethyl diallyl ammonium chloride, 0.2 part of ammonium persulfate and 0.2 part of sodium bisulfite. The inhibiting and anti-sloughing agent is prepared by the following steps of: uniformly mixing the raw materials and introducing nitrogen into the mixture to make the liquid in a container form colloid; pelletizing the colloid to form pellets by using a pelletizer; drying the pellets by using a boiling fluidized bed and pulverizing the dried pellets by using a pulverizer. The agent has the functions of improving penetration rate of machinery and reducing filtrate loss and high salt and calcium resistance, can effectively improve contamination resistance of the drilling fluid, and is particularly suitable for fresh water and salt water liquid systems.
Description
Technical field:
The present invention relates to drilling fluid additive, particularly a kind of inhibiting and anti-sloughing agent for drilling fluid.
Background technology:
Anti-collapse dose of the inhibition of disposing in the present drilling fluid; For the hydration swelling and the dispersion that suppress well body crag, effect is relatively poor, and the various geological conditions that pierce after underground are comparatively complicated; Sometimes need under multiple complex geological condition, use; Especially in the drilling environment that the water yield of down-hole is bigger, existing inhibiting and anti-sloughing agent for drilling fluid effect is undesirable, can not satisfy the actual user demand of drilling well.
Summary of the invention:
The objective of the invention is to design a kind of can be under multiple water pendular ring border the good inhibiting and anti-sloughing agent for drilling fluid of result of use.
Technical scheme of the present invention is that a kind of inhibiting and anti-sloughing agent for drilling fluid is characterized in that: it comprises the acrylamide monomer of 450-650 weight part; The 50-250 parts by weight of acrylic, the salt of wormwood of 100 weight parts or Pottasium Hydroxide, the sodium hydroxide of 50 weight parts; The ammoniacal liquor of 50 weight parts; The dimethyl diallyl ammonium chloride of 100 weight parts, the ammonium persulfate of 0.2 weight part, the sodium sulfite anhy 96 of 0.2 weight part; After above-mentioned raw materials mixed, feed nitrogen, make the liquid in the container become colloid; Colloid is processed particle through tablets press; Again particle is dried through boiling sulfuration bed; Get into kibbler again and pulverize, promptly process the present invention.
The present invention has the raising ROP, falls the effect of leak-off, and anti-salt, anticalcium ability are strong, can effectively improve the drilling fluid contamination resistance, are specially adapted to fresh water, salt water liquid system.
Embodiment:
Be described with reference to the accompanying drawings embodiment,
