Description
Technical field
The present invention relates to drilling plugging agent, particularly one expansion consolidation type plugging agent.
Background technology
The expansile plugging agent that has common in petroleum drilling has diesel oil bentonite slurry, diesel oil bentonite slurry be by diesel oil, wilkinite, soda ash, lime etc. by a certain percentage mixture form, when mixture is pumped to after drop ply contacts with water, the bentonite clay particle suspended starts aquation, and separate from oil, form a tough and tensile greasy filth block, thus reach leak stopping object.This blocking agent is that petroleum drilling has played effect, but there is following shortcoming or deficiency simultaneously: 1. the swollen expansion multiple of water breakthrough is high, but compressible after expanding, and whether have intensity, validity period is short; Although 2. diesel oil bentonite slurry can expand, do not have intensity, do not have solidifiability, huge discharge circulation under external force is just damaged, 3. cross-linked polymer plugging agent is without coagulability, heat and salinity tolerance ability, and validity period is short, compressible rear irrecoverable, easily there is multiple leakage, weak effect; 4. composite usage tackles permeability loss, in, have certain plugging effect in the construction of cracklin and porous formation leakage, but patching materials consumption is large, and plugging time is long, easily causes down-hole complex accident; Cannot solve when running into large-scale leakage; Cause repeatedly repeating leakage, cause great financial loss, directly affect plugging effect and drilling project.
Summary of the invention
The object of this invention is to provide a kind of expansion consolidation type plugging agent, there is rate of expansion high, viscous flow ability is strong, have coagulability shut-off capacity strong, good fluidity has pumpability and easily enters drop ply deep, and the strong validity period of saline-alkaline tolerance is long, effectively overcome or avoid the shortcoming that exists in above-mentioned existing leak stopping or deficiency, effectively improve the plugging effect of macropore, subterranean stream, cavern leakage, shorten drilling period, improve drill speed.
Expansion consolidation type plugging agent of the present invention, its composition and content, content is weight part: sulphoaluminate expander 0.5-2; Polypropylene fibre 1-4; Water-absorbent expansive polymer 0.1-1; Super absorbent resin SAP1-5; Expanded starch 2-6; Anti-salt clay 2-6; Calcium carbonate 20-40; High adhesive aggregation anionic cellulose PAC-HV0.1-0.5;
Compound method: by above-mentioned substance by its component and content, under normal temperature and pressure, add successively in kneader with conventional formulation method, mixing and stirring, treat that it dry, pulverize into the particulate preparation that particle diameter is 0.01mm – 0.5mm.
Wherein, described anti-salt clay is attapulgite.
The present invention's tool compared with existing plugging agent has the following advantages or beneficial effect:
1, have expansion, concreteness, have again certain intensity, after condensation, volume does not reduce, and validity period is long.
2, in leakage channel, retentivity is strong, and plugging effect is good, and leak stopping success ratio is high;
3, volume invariability after condensation, do not go out free water, sealing ratiod is high;
4, there is very strong condensation performance, affect little by external force (turn on pump circulation and pressure excitement) after condensation in leakage channel,
5, there is good mobility and performance is carried in suspension, be easily trapped in leakage channel.
6, temperature and pressure are little to leak stopping slurry performance impact, and have fine saline-alkaline tolerance;
7, use range is wide, is particularly suitable for the blocking construction of subterranean stream, the leakage of large fracture Caves formation depletion.Nontoxic, environmentally safe, operational safety, can not cause down-hole complex accident.
