The plugging agent provided by the invention has the characteristics of high expansion rate, viscous flow capacity, plugging capacity, strong salt-resistance, flowability, pumpability, good coagulability, simple process, safe and quick construction, long coagulability, wide source of raw materials, high plugging success rate and the like, and is widely applied to plugging processes of large pore paths, subterranean rivers and great Karst cave leakage strata in petroleum and geological drilling.
Description
Technical field
The present invention relates to drilling plugging agent, particularly the fixed type plugging agent of a kind of expansion.
Background technology
The expansile plugging agent that has common in petroleum drilling has diesel oil bentonite slurry, diesel oil bentonite slurry is to be mixed by a certain percentage and to be formed by diesel oil, wilkinite, soda ash, lime etc., after mixture is pumped to drop ply and contacts with water, the bentonite clay particle suspending starts aquation, and separate from oil, form a tough and tensile greasy filth piece, thereby reach leak stopping object.This blocking agent is that petroleum drilling has been brought into play effect, but exists following shortcoming or deficiency simultaneously: 1. the swollen expansion multiple of water breakthrough is high, but compressible after expanding, and whether has intensity, and validity period is short; Although 2. diesel oil bentonite slurry can expand, and there is no intensity, does not have solidifiability, large discharge capacity 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, in the construction of cracklin and porous formation leakage, have certain plugging effect, but the patching materials amount of expending is large, plugging time is long, easily causes down-hole complex accident; When running into large-scale leakage, cannot solve; 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 the fixed type plugging agent of a kind of expansion, 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, the shortcoming or the deficiency that effectively overcome or avoid existing in above-mentioned existing leak stopping, effectively improve the plugging effect that macropore, subterranean stream, cavern are missed, shortened drilling period, improved drill speed.
The fixed type plugging agent of expansion of the present invention, its composition and content, content is weight part: sulphoaluminate expander 0.5-2; Polypropylene fibre 1-4; Water-swelling type polymkeric substance 0.1-1; Super absorbent resin SAP 1-5; Expanded starch 2-6; Anti-salt clay 2-6; Calcium carbonate 20-40; High adhesive aggregation anionic cellulose PAC-HV 0.1-0.5;
Compound method: above-mentioned substance, by its component and content, under normal temperature and pressure, is added in kneader with normal compound method successively, and mixing and stirring, treats that it dry, pulverize into the particulate state goods that particle diameter is 0.01mm – 0.5mm.
Wherein, described anti-salt clay is attapulgite.
The present invention compares with existing plugging agent, and tool has the following advantages or beneficial effect:
1, have expansion, concreteness, have again certain intensity, after condensing, volume does not dwindle, 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, condense after volume invariability, do not go out free water, sealing ratiod is high;
4, there is the very strong performance of condensing, affected by external force (turn on pump circulation and pressure are excited) little,
5, there is good mobility and suspension and carry performance, 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 in debt of large fracture Caves stratum.Nontoxic, environmentally safe, operational safety, can not cause down-hole complex accident.
