Description

A kind of leak-stopping cement mortar
Technical field
The present invention relates to oil gas field of engineering technology, more particularly to a kind of leak-stopping cement mortar.
Background technology
In petroleum exploration and development process, due to being exploited by rolling for many years, the production string of Oil/gas Well undergoes all the year round The corrosion of stratum water is also easy to produce breakage, to ensure the recovery ratio of Oil/gas Well, special closure operation need to be carried out to sleeve pipe;Furthermore, Because long-term injecting water is washed away, macropore is formed in high permeability zone, cause injection water monolayer to advance by leaps and bounds, High water cut is shown as very in oil well To water logging, accordingly, it would be desirable to Plugging Water Zones borehole, reselecting layer position carries out reperforation operation, and series of strata are adopted to adjust note, excavates Interlayer potentiality.In above-mentioned work, later stage safely and effectively operation is realized, it is necessary to the drop ply and borehole that are blocked have very well Integrality and bearing capacity, such as fracturing work, required bearing capacity is higher, the large-scale volume fracturing skill of such as shale gas Art, maximum pressure is up to 90MPa, and this proposes requirement very high to bobbin seal bearing capacity.
Chinese invention patent CN101318799 discloses a kind of marine oil gas well cement paste for well cementation, with very high low Warm intensity, Free water is small, and the thickening time can be adjusted, but 60 DEG C/24 hours intensity of the cement mortar is only 25MPa;And middle promulgated by the State Council Bright patent CN101160268 discloses a kind of versatility ultrahigh-strength fiber-reinforced mortar high, can carry strength of cement grout 180MPa or so is raised to, but invention only illustrates to be applied to bridge structural member, dam structure component, ocean structure component, building Build etc.;It is high that Chinese invention patent CN104918899 discloses a kind of initial strength, can carry out in advance steam-cured high-strength The manufacture method of degree cement admixture and concrete, this kind of cement pulp-water has used a large amount of high-performance water reducing agents than low, is passing through After 20 DEG C of maintenances in 7 days, cement strength can reach 110MPa, but this kind of cement mortar mainly applies to field of civil engineering.
But all there is certain deficiency and defect in above-mentioned ultrahigh-strength cement slurry:1) high intensity used in Oil/gas Well industry The compression strength of mortar architecture is difficult to reach design requirement (more than bearing capacity 90MPa);2) general compression strength can reach Cement mortar to 90MPa is generally all used and, because such cement mortar is thicker, had with building, the industry such as civil engineering Poor mobility, it is difficult to pump into well, is not appropriate for being applied to oil well industry;3) general high-intensity cement paste will reach The intensity of 90MPa, typically will be at 7 days or so, it is desirable to reach 90MPa's in 48 hours, it is necessary to wait solidifying or maintenance time long Intensity, realizes difficult.
