Abstract
The invention discloses a raw material formula and production method of bentonite for well drilling. The mass percentage of raw materials is as follow: 92-96% of calcium-based soil, 2-5% of alkali powder, 0.5-1.5% of carboxymethylcellulose, and 1-1.5% of polypropanamide. The invention also discloses a method for producing bentonite for well drilling, wherein the process flow is: raw ore of calcium-based soil, smashing, rolling, feeding, stirring with water, adding alkali powder, carboxymethylcellulose, polypropanamide and stirring, stacking for one week to half a month after reaction, drying, grinding, and sieving. The application of bentonite produced in the method in petroleum geology drilling and non-permeation project of power stations, reservoirs and dams as well as the pipe-jacking construction of cities can lubricate the drill pipe and the drill better and take away the rock debris, and form a mud wall which is thin, but strong and staunch.
Description
Technical field
The present invention relates to a kind of bentonite origin material formula and working method, the drilling well that relates in particular to a kind of lubricant effect and film forming better effects if belongs to bentonitic production field with bentonite origin material formula and working method.
Background technology
Wilkinite be a kind of be the clay class mineral of main ingredient with the smectite, have the intensive water-absorbent, can absorb the water that is equivalent to 8 times of volumes own, 10～30 times of volumetric expansions are in the aqueous solution and suspend and gelatinized.When items such as carrying out oil, pneumatic drill well is worked, use mud to come cools reamer head, remove chip, protect the borehole wall to reach pressure evenly.Wilkinite good dispersivity, slurry-outlet quantity are big, therefore are the ideal materials of making drilling mud.As the wilkinite of drilling mud, most important technical requirements is suspension character, wet screening analysis and moisture content.The vital role of wilkinite in drilling well makes its consumption very big.It is reported, on average whenever adopt a bite well, approximately use 8 tons of wilkinites.
Wilkinite is used in present drilling well; Calcium-base bentonite is arranged; Also have calcium to receive wilkinite, it is good receiving bentonitic effect with calcium, but because the prescription of its raw materials for production (calcium base soil and ground caustic) is not very desirable; And do not add other more effectively assistant chemical preparation, so its lubricant effect and film forming effect also are not very desirable.And, all will produce significant meaning in any one the little progress aspect lubricant effect and the film forming effect for the drilling well industry, its speed for drilling well, efficient and construction quality all have very big prograding.
Summary of the invention
The object of the invention with regard to the drilling well that is with bentonitic deficiency a kind of lubricant effect and film forming better effects if to be provided to present drilling well with bentonite origin material formula and working method.
The present invention realizes above-mentioned purpose through following technical scheme:
Drilling well of the present invention is with in the bentonite origin material formula, and each raw material and mass percent are following: calcium base soil 92-96%, and ground caustic 2-5%, CMC 99.5 0.5-1.5% gathers propionic acid amide 1-1.5%.
CMC 99.5 is that cellulosic ethyloic is rolled into a ball substitution product.According to its molecular weight or replacement degree, can be consoluet or insoluble polymer, the latter can be used as the weak-type cationite, in order to separate neutrality or basic protein etc.CMC 99.5 can form full-bodied colloid, solution, adhesion is arranged, thickening, flow, emulsification dispersion, figuration, water conservation, protective colloid, film forming, acidproof, salt tolerant, outstanding characteristic such as turbid; And physiology is harmless, therefore in fields such as food, medicine, daily use chemicals, oil, papermaking, weaving, building produce, is used widely.
CMC 99.5 and ground caustic react and can obtain Xylo-Mucine (CMC), and in drilling well, CMC has following effect: the mud that 1. contains CMC can make the borehole wall form Bao Erjian, filter cake that perviousness is low, and WL is reduced; 2. after in mud, adding CMC, can make rig obtain low zero gel, make mud be easy to emit to be rolled in the gas of the inside, abandon very soon in the mud pit mincing simultaneously; 3. drilling mud is the same with other suspended dispersed body, has certain phase that exists, and adds to make behind the CMC it stable and prolong and have the phase; 4. the mud that contains CMC seldom receives fungal effects, therefore, needn't keep very high pH value, also needn't use sanitas; 5. contain CMC and make drilling mud flushing fluid treatment agent, can resist the pollution of various solubility salts; 6. contain the mud of CMC, have good stability, even temperature still can reduce dehydration more than 150 ℃.
Gather the effect that propionic acid amide has the water breakthrough of preventing, reduces frictional resistance, improves RF, can further improve the drill bit working efficiency.
Particularly, each raw material and mass percent are following: calcium base soil 94.8%, and ground caustic 3%, CMC 99.5 1% gathers propionic acid amide 1.2%.
Each raw material and mass percent are all right as follows: calcium base soil 92%, and ground caustic 5%, CMC 99.5 1.5% gathers propionic acid amide 1.5%.
Each raw material and mass percent are all right as follows: calcium base soil 96%, and ground caustic 2%, CMC 99.5 1% gathers propionic acid amide 1%.
Each raw material and mass percent are all right as follows: calcium base soil 94%, and ground caustic 3%, CMC 99.5 1.5% gathers propionic acid amide 1.5%.
Bentonitic working method is used in drilling well among the present invention, and its work flow is: calcium base soil raw ore → pulverizings → pair roller → feed → add water stirrings → adding ground caustic, CMC 99.5, gather propionic acid amide stirring → reaction stacking one week to first quarter moon → oven dry afterwards → levigate → sieve.
In said oven dry flow process, oven dry back moisture controlled is in 13%.
Beneficial effect of the present invention is:
With the wilkinite that the present invention produced be used for petroleum geology probing and power station, reservoir dam is impermeable and city jacking construction etc.; Can lubricate drilling rod, drill bit better; Take away landwaste; Formation strong and thin and fluid-tight grout wall can further improve construction quality, accelerate working speed, raise the efficiency.
