Abstract
The agent of a kind of leak stopping pressure-bearing, its composition and content are weight part: calcium carbonate 20-30, perlite powder 10-15, G level oil well cement 2-5, quartz sand 10-15; Calucium Silicate powder 10-20, oyster shell whiting 10-15, calcium hydroxide 1-4, drilling fluid xanthan gum 0.1-0.4, Polyacrylamide 0.1-0.4, Polyanionic Cellulose 0.1-0.4; Above-mentioned substance, by its component and content, under normal temperature and pressure, adds in molten device successively with conventional formulation method, mixing and stirring, treats that it dry, pulverize into the particulate preparation of 0.05mm – 0.8mm.It is high that the present invention has sealing ratiod, suspension property is good, there is after condensation very high setting strength, enter leakage channel deep, in the crack of difference leakage type, bearing capacity according to the leakage degree of depth, lithology, intensity adjustment, after pressurization sealing liquid solidifies, can have very high condensation performance and pressure-bearing effect.Extensively apply in oil, geological drilling technique, special adaptation, is applied in Fractured hard formation and Caves stratum.
Description
Technical field
The present invention relates to drilling plugging agent material, particularly a kind of leak stopping pressure-bearing agent.
Background technology
The leak stopping slurry adopted in petroleum drilling, be generally the nut-shell of different-grain diameter, cotton seed hull, single material such as envelope, diesel oil bentonite slurry, mica, husk, at the scene as the agent of leak stopping pressure-bearing, realize the construction of pressurization sealing, these plugging agents are that petroleum drilling stoppage engineering aspect has played effect.But it also exists following shortcoming or deficiency simultaneously: 1. above-mentioned plugging agent only small-sized leakage and bearing requirements not high time play a role, still do not reach the requirement of pressure-bearing, leak stopping is repeatedly caused on the stratum that the large bearing requirements in, crack large to hole is higher; What 2. plugging agent particle diameter was large enters less than in crack, and what particle diameter was little is detained incessantly in leakage channel; 3. pressure-bearing agent dose hour, can not be detained, frame does not play bridge, holds incessantly pressure, when dosage is large, poor fluidity, Portability is bad, and easily sealing is difficult to pump into, and easily causes high pump pressure, is destroyed further by drop ply again and form new crack during pump pressure height; 4. pressurization sealing slurry enter leakage stratum after because of performance of not condensing, turn on pump circulating pressure excitement time can miss again, do not reach the object of pressure-bearing; 5. bad with formation rock adsorptivity, there is no cementation and cementation, cause a large amount of pressure-bearing material to return out well head, cause a large amount of wastes; 6. pressure-bearing material usage is large, and pressure-bearing repeatedly, the pressure-bearing time is long, pressure-bearing weak effect, causes down-hole situation complicated, does not finally reach pressure-bearing object.
Summary of the invention
The object of this invention is to provide the agent of a kind of leak stopping pressure-bearing, adopt inorganic, organic multiple pressure-bearing material, through different compatibility, make pressure-bearing agent, its sealing ratiod is high, and suspending, it is good to carry performance, can enter leakage channel deep, pressure-bearing shut-off capacity is high, engineering time is short, and pump pressure is low, avoids causing secondary injury to leakage stratum, bearing capacity can be missed in the crack of type in difference and be adjusted according to the leakage degree of depth, lithology, intensity, has very high ultimate compression strength and pressure-bearing effect.Effectively overcome or avoid the shortcoming that exists in above-mentioned prior art or deficiency.
Leak stopping pressure-bearing of the present invention agent, its composition and content, content is weight part: calcium carbonate 20-30; Perlite powder 10-15; G level oil well cement 2-5; Quartz sand 10-15; Calucium Silicate powder 10-20; Oyster shell whiting 10-15; Calcium hydroxide 1-4; Drilling fluid xanthan gum 0.1-0.4; Polyacrylamide 0.1-0.4; Polyanionic Cellulose 0.1-0.4.
Compound method: by above-mentioned substance by its component and content, under normal temperature and pressure, add in molten device successively with conventional formulation method, mixing and stirring, treat that it dry, pulverize or be screened into the powdered preparations that particle diameter is 0.05mm – 0.8mm.
The present invention compared with prior art tool has the following advantages or beneficial effect:
1, bearing capacity is strong, and existing physical clogging performance, has again chemical coagulation effect;
2, good fluidity, suspension carrying capacity is strong, and can enter deep, low-pressure stratum crack, plugging effect is good;
3, with formation lithology excellent adsorption, connect, cementation characteristic is good, and there is performance of well condensing, low pressure ravelly ground bearing capacity can be improved;
4, performance is even, easily pumps into open-ended, the secondary crack that the formation damage that high pump pressure can not be caused to cause is formed, and pressurization sealing success ratio is high;
5, technique is simple, and the shove time is short, and rate of set is fast, and sealing ratiod is high, pressurization sealing Be very effective, significantly shortens the pressurization sealing cycle;
6, compatibility is good, can with other multiple leak stopping starch with the use of, matched performance is good, has good compatibility performance;
7, use range is wide, pressure-bearing can construct, all have good pressurization sealing effect in dissimilar formation lithology well section;
8, little to environmental influence, nontoxic, pollution-free, easy and safe to operate.
