Abstract
The present invention discloses petroleum exploration well-drilling liquid used non-blooming anti-collapse and anti-falling filtration agent, which is confected by coal gangue 500Kg, waste orlon thread 270Kg, sodium hudroxide 100Kg, formaldehyde 20Kg, sodium nitrite 30Kg, sodium bisulfate 30Kg, phenol 50Kg, and water 3000Kg. The cost of the processing raw material of the product of the present invention is low, compared with the same kind of the product, the cost of the well-drilling slurry can be lowered by 30 percent, during the well-drilling process, the using volume is less, in the fresh water, 1 percent volume can be added, in the sea water, 3percent volume can be added, the performance is better than the performance of all the lignite resin products, the circumference of the drilling tool can form smooth and hard filtration cake to prevent the well wall from collapsing, to control the mudstone and the clay shale from swelling by absorbing water, to control the water lost volume, so as to improve the well-drilling schedule. The raw material adopted by the present invention is all non-blooming material, which has no interference to geological log, the product petroleum field is large in demand volume, and great in market potential. The present invention also discloses the preparation method for above anti-collapse and anti-falling filtration agent.
Description
Technical field
A kind of non-fluorescence collapse-proof fluid loss additive for oil exploration drilling fluid when the present invention relates to.
Technical background
Along with increasing of oil exploration drilling quantity, the consumption of chemical processing agent also increases relatively, especially the Party A recovers the oil to the restriction of Party B's drilling mud cost, the Party B is not wanted in drilling well, and option selects that capability and performance is good, consumption is few, cheap, the chemical processing agent that can reduce drilling cost, yet the existing dosage of conventional salt resistant filter loss reduction agent in fresh water is 3%, dosage 5% in seawater, and cost is than higher.
Summary of the invention
The objective of the invention is to provide that a kind of adult is low, consumption is few, the non-fluorescence collapse-proof fluid loss additive for oil exploration drilling fluid of superior performance in order to overcome the deficiency that prior art exists.
For realizing that the technical scheme that purpose of the present invention provides is:
A kind of non-fluorescence collapse-proof fluid loss additive for oil exploration drilling fluid is got by following component preparation: coal gangue 500Kg, Waste Polyacrylonitrile Fibre 270Kg, caustic soda 100Kg, formaldehyde 20Kg, inferior sodium 30Kg, sodium bisulfite 30Kg, phenol 50Kg, water 3000Kg.
Prepare the method for above-mentioned non-fluorescence collapse-proof fluid loss additive for oil exploration drilling fluid, comprise the following steps:
A, with phenol 50Kg, formaldehyde 20Kg, inferior sodium 30Kg, sodium bisulfite 30Kg with water 1500Kg is disposable feeds intake, under alkaline condition, carry out condensation and sulfonation reaction, generate sulfonated-pheno-formoldehyde resin;
B, Waste Polyacrylonitrile Fibre under alkaline condition, under 110 ℃～120 ℃ of temperature and pressure 0.6Mpa～0.8Mpa condition, hydrolyzed polyacrylonitrile;
C, with the colliery powder that processes at caustic soda 100Kg and water 1500Kg, under 110 ℃～120 ℃ of temperature and pressure 0.6Mpa～0.8Mpa condition, reaction generates Sodium salts humic acids;
D, with top three kinds of intermediates, add synchronously in the reactor, under 110 ℃～120 ℃ of temperature and pressure 0.6Mpa～0.8Mpa condition, resin reaction forms multiple copolymer, and is spray-dried and get.
Principal reaction mechanism of the present invention:
Product of the present invention is a pulvis, is alkalescence, good water solubility, and the cost that processes raw material is low, and adopting the chemical fibre offal of coal gangue and other abandonments is main raw material, is synthesized into by the subsidy Chemical Composition, compared with similar products, can reduce drilling mud cost 30%; In drilling process, consumption is few, and the dosage in fresh water is 1%, and dosage 3% in seawater, and performance is better than the performance of all valchovite series products, as falls the dehydration index; The present invention is suitable for wide, on land, the sea all can use, and is cheap, reduces the drilling mud cost greatly, is first-selected anti-collapse dose in the present domestic anti-collapse and anti-falling filtration agent class, filled up the blank of fluid loss agent.The present invention plays drilling tool and forms smooth and tough and tensile filter cake on every side in drilling process, prevents slump in, the water-swelling of control borehole wall mud stone mud shale, and the control fluid loss can improve drilling progress.The present invention adopts starting material all to be no fluorescent material, and is noiseless to geological logging, and this every demand in product oil field is big, and from the drilling well to the completion, average every mouthful of well is with 5～8 tons, and market potential is big.
