Description
Technical field
The present invention relates to drilling plugging agent, particularly a kind of leak stopping toughener.
Background technology
The plugging agent that existing petroleum drilling uses, the material such as general employing calcium chloride, silicate (water glass potassium silicate) etc., steel ball, perlite, mosaic, calcium carbonate does leak stopping toughener, be added in dissimilar plugging agent formula, to improve the intensity of plugging agent, although these plugging agents have played effect for petroleum drilling, but there is following shortcoming or deficiency: (1) calcium chloride, silicate have a big risk simultaneously, dosage difficulty in leak stopping slurry is grasped, the speed improving leak stopping slurry intensity is difficult to control, the speed of condensation is difficult to adjustment, and construction risk is large.(2) inorganic salt are added in testing instrument, large to leak stopping slurry performance impact, cause fast thickening, layering, coagulating sedimentation, leak stopping are starched unstable.(3) in leak stopping slurry, add the material such as perlite, mosaic, calcium carbonate of inertia, there is no coagulability to the raising of intensity is uneven, and due to hardness fragile to pump greatly, causing can not sequential production, and plugging time is long; (4) large on the impact of pump, cause down-hole situation complicated time serious, leak stopping is starched can not inject drop ply, and drilling tool can rise out, is solidificated in well; (5) function singleness, intensity is low, bad adaptability, and use cost is high; (6) the blocking construction cycle is long, and in crack and Karst Cave Formation leak stopping, because the low sealing ratiod that causes of plugging agent intensity is low, plugging effect is poor, increases construction cost.
Summary of the invention
The object of this invention is to provide a kind of leak stopping toughener, adopt the grain diameter of sizes different hardness, Granular composite when ground is prepared is in leak stopping system, after entering leakage channel, under reservoir pressure and temperature, plugging agent condenses into coagulation structure at leakage channel, thus effectively form the strong congealed solid of anti-pressure ability, add the intensity of plugging agent, effectively overcome or avoid the shortcoming that exists in above-mentioned prior art or deficiency, effectively improving plugging effect and drilling speed
