Description
Technical field
The present invention relates to drilling plugging agent, particularly the fixed type plugging agent of a kind of low density.
Background technology
In petroleum drilling, bore meeting thief formation often adopts diesel oil bentonite slurry, common leak stopping slurry to add the method leak stopping that bridging material, clear water add bridging material, although these blocking methods have solved temporary transient leakage, but exist following shortcoming or deficiency: 1. leak stopping pulp density high-density adjustable space is little simultaneously, be difficult to solve a leakage difficult problem for low-pressure stratum; 2. because reservoir pressure is low, leak stopping pulp density is high-leveled and difficult causes blocking construction difficulty large to adjust, and plugging time is long, misses more and more serious; 3. above-mentioned blocking method has certain effect to some mesolow power leakage stratum leak stopping, when running into low-pressure stratum, long bore hole low pressure leakage, cannot solve; 4. when adding inert material, can increase density, add the leak stopping slurry of bridging material to be difficult to be trapped in leakage channel, affect plugging effect.5. plugging time is long, and density can be more and more higher, and leakage can be more and more serious, causes repeatedly repeating leakage, causes great financial loss.
Summary of the invention
The object of this invention is to provide the fixed type plugging agent of a kind of low density, adopt leak stopping pulp density low, in low pressure leakage channel, be easy to be detained, after condensing, there is the plugging agent that some strength has leakproof leakage function, density variable range is wide, can adjust according to the different pressures on leakage stratum the density of leak stopping slurry.The shortcoming or the deficiency that effectively overcome or avoid existing in above-mentioned existing leak stopping, improve plugging effect effectively, shortens drilling period, improves drill speed.
The fixed type plugging agent of low density of the present invention, its composition and content, content is weight part: calcium carbonate 10-20; Oyster shell whiting 10-20; Flyash 20-30; Float pearl 10-20; Hollow glass ball 10-20; Sodium dodecylbenzene sulfonate 0.1-1; XC biological polymer 0.5-1; Polyacrylamide PAM 0.5-1; Calcium hydroxide 1-5.
Compound method: above-mentioned substance, by its component and content, is added in reactor, stir mixed 6-8 hour in normal pressure, 40-55 ℃ condition, then add in moisture eliminator, treat that it dry, pulverize into the Powdered goods of 0.01mm-0.3mm.
Wherein, the granularity of described hollow glass ball is 5-125um.Described raw XC thing polymkeric substance is drilling fluid xanthan gum.
The present invention compares with existing bridging agent, and tool has the following advantages or beneficial effect:
1, it is large that leak stopping pulp density is adjusted space, and retention performance is good, and shut-off capacity is strong, and leak stopping success ratio is high;
2, can adjust according to Different Strata pressure the density of leak stopping slurry;
3, can hold a large amount of patching materialss, density does not raise, and still has fine delay shut-off capacity;
4, when the blocking construction of low pressure leakage stratum, low density leak stopping slurry is more easily trapped in leakage channel, can reduce leakage degree, improves leak stopping success ratio.
5, under low density state, good with other plugging agent compatibleness, enter in the leakage channel of leakage crack, improve shutoff bearing capacity.
6, use range is wide, can be used for the blocking construction in low-pressure stratum and in stratum in debt, the blocking construction of the large, medium and small crack of simultaneous adaptation hard formation Caves formation leakage.
7, nontoxic, environmentally safe, operational safety, can not cause down-hole complex accident.
