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 adopting in petroleum drilling, be generally the materials such as the nut-shell, cotton seed hull of different-grain diameter, single envelope, diesel oil bentonite slurry, mica, husk, at the scene as the agent of leak stopping pressure-bearing, realize the construction of pressure-bearing leak stopping, these plugging agents are that effect has been brought into play in petroleum drilling stoppage engineering aspect.But it exists following shortcoming or deficiency simultaneously: 1. above-mentioned plugging agent only plays a role when not high in small-sized leakage and bearing requirements, does not still reach the requirement of pressure-bearing, and leak stopping is repeatedly caused on, crack large bearing requirements higher stratum large to hole; 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, and frame does not play bridge, and hold incessantly and press, when dosage is large, poor fluidity, Portability is bad, and easily sealing is difficult to pump into, and easily causes high pump pressure, again drop ply is further destroyed and form new crack when pump pressure is high; 4. pressure-bearing leak stopping slurry enters behind leakage stratum because of the performance of not condensing, and during the excitement of turn on pump circulating pressure, can miss again, does 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 materials to return out well head, cause a large amount of wastes; 6. pressure-bearing material usage is large, pressure-bearing repeatedly, and the pressure-bearing time is long, and 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 compatibilities, make pressure-bearing agent, its sealing ratiod is high, suspends that 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 leakage stratum to cause secondary injury, bearing capacity can be missed in the crack of type and adjust according to the leakage degree of depth, lithology, intensity in difference, has very high ultimate compression strength and pressure-bearing effect.Effectively overcome or avoid the shortcoming or the deficiency that in above-mentioned prior art, exist.
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; XC biological polymer 0.1-0.4; Polyacrylamide 0.1-0.4; Polyanionic Cellulose 0.1-0.4.
Compound method: above-mentioned substance, by its component and content, under normal temperature and pressure, is added in molten device with normal compound method successively, and mixing and stirring, treats that it dry, pulverize or be screened into the Powdered goods that particle diameter is 0.05mm – 0.8mm.
Wherein, described XC biological polymer is drilling fluid xanthan gum.
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, can enter deep, low-pressure stratum crack, and plugging effect is good;
3, with formation lithology excellent adsorption, connect, cementation characteristic is good, and there is the performance of well condensing, can improve low pressure ravelly ground bearing capacity;
4, performance is even, easily pumps into open-ended, the secondary crack that can not cause formation damage that high pump pressure causes to form, and pressure-bearing leak stopping 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, and pressure-bearing plugging effect is remarkable, significantly shortens the pressure-bearing leak stopping cycle;
6, compatibility is good, can be used in conjunction with other multiple leak stopping slurries, and matched performance is good, has good compatibility performance;
7, use range is wide, can in dissimilar formation lithology well section, pressure-bearing construct, and all has good pressure-bearing plugging effect;
8, little to environmental influence, nontoxic, pollution-free, easy and safe to operate.
