Abstract
The invention discloses a hard compound reinforcing bridging agent comprising the following materials in parts by weight: 30-40 parts of shell powder, 15-30 parts of calcium carbonate, 30-40 parts ofnatural hard rubber and 20-30 parts of natural hard fiber. A preparation method comprises the following step: uniformly mixing and stirring the materials in parts by weight at normal temperature and pressure. The hard compound reinforcing bridging agent is prepared by compounding elastic plugging materials with a certain rigidity according to a scientific mixing proportion, and rigid solid granules with different granule diameters enter leaking cracks, leaking pores and leaking passages in the plugging construction process and play bridging and supporting roles in the leaking cracks, the leaking pores and the leaking passages with different sizes. The invention has high supporting capability and plugging characteristic, wide using range, and the like and is widely applied to leakage prevention and plugging technologies of oil and geological exploration.
Description
One, technical field
The present invention relates to the drilling leakage blockage bridging agent, particularly a kind of hard compound reinforcing bridging agent.
Two, background technology
In the drilling process of petroleum exploration and development, leakage often takes place, the general materials such as nut-shell, mica, vermiculite, shell that use carry out blocking construction, for effect has been brought into play in the drilling leakage blockage construction, but it exists following shortcoming and defect simultaneously: 1. because not only there is the soft lithology of mud sandstone in the absorption well segment length but also exist limestone, carbonate hard lithology, therefore, take place to optimize the performance of the plugging agent that adapts with stratum rock signature, the intensity of plugging agent, the particle diameter of plugging agent, the prescription of plugging agent as early as possible after the leakage, cause the repeated multiple times blocking construction; 2. plugging time length, high material consumption, complexcase are many, and leak stopping cost height directly influences drilling rate, and the leak stopping success ratio is low; 3. these bridging agents do not have enough resistance to compressions, anti-opening and shear strength, the granulate material hardness that has is high again, do not match with the leakage formation lithology, not owing to rock frame stress deformation changes its geometrical shape in construction, reduce plugging effect, exactly because pellet hardness causes stratum crushing greatly, make the stratum repeat leakage.
Three, summary of the invention
The purpose of this invention is to provide a kind of hard compound reinforcing bridging agent, adopt the rigid material of different-grain diameter and the composite composition of resilient material of different hardness to close, by to the leakage borehole wall fissured effective support and effectively shutoff, make the different-grain diameter patching materials enter the leakage channel deep, improve the bearing capacity on stratum, prevent rock frame stress deformation and change its geometrical shape, strengthen bearing resistance, improve plugging effect, the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art.
Hard compound reinforcing bridging agent of the present invention, its composition and content, content are weight part:
Oyster shell whiting 30-40; Lime carbonate 15-30; Natural vulcanite 30-40; Natural stiff fibre 20-30.
Compound method: the material of above-mentioned component is by its component and content, and mixing and stirring gets final product at normal temperatures and pressures.
The present invention and existing plugging agent have following advantage or beneficial effect:
1, the plugging agent component not only contains rigid material but also contain resilient material,
2, in leakage channel, have very strong bridge formation supporting role, guarantee that plugging agent enters the leakage channel deep.
3, in irregular leakage channel, have very high filling plugging action, improved the leak stopping success ratio.
4, the plugging agent particle size distribution range is wide, can fill dissimilar leakage crack and leakage channel.
5, use range is wide, both has been fit to the siltstone soft formation, is fit to the carbonate hard formation again.
6, nontoxic, pollution-free, preparation is simple, construction safety, does not damage pump, can construct leak stopping success ratio height continuously.
Five, embodiment:
A kind of hard compound reinforcing bridging agent, its composition and content, content are weight part:
Oyster shell whiting 30-40; Lime carbonate 15-30; Natural vulcanite 30-40; Natural stiff fibre 20-30.
Compound method: the material of above-mentioned component is by its component and content, and mixing and stirring gets final product at normal temperatures and pressures.
During use, in plugging drilling fluid, add the multifunctional connecting bridging agent of the present invention of the 2%-15% of people's plugging drilling fluid total amount.Provide specific embodiment below:
The 1st example
Oyster shell whiting 30; Lime carbonate 15; Natural vulcanite 30; Natural stiff fibre 20.Mixing and stirring at normal temperatures and pressures adds 2% multifunctional connecting bridging agent of the present invention of people's plugging drilling fluid total amount in plugging drilling fluid.
The 2nd example
Oyster shell whiting 33; Lime carbonate 18; Natural vulcanite 33; Natural stiff fibre 23.Mixing and stirring at normal temperatures and pressures adds 8% multifunctional connecting bridging agent of the present invention of people's plugging drilling fluid total amount in plugging drilling fluid.
The 3rd example
Oyster shell whiting 35; Lime carbonate 25; Natural vulcanite 35; Natural stiff fibre 25.Mixing and stirring at normal temperatures and pressures adds 12% multifunctional connecting bridging agent of the present invention of people's plugging drilling fluid total amount in plugging drilling fluid.
The 4th example
Oyster shell whiting 40; Lime carbonate 30; Natural vulcanite 40; Natural stiff fibre 30.Mixing and stirring at normal temperatures and pressures adds 15% multifunctional connecting bridging agent of the present invention of people's plugging drilling fluid total amount in plugging drilling fluid.
Wherein the 1st example, the 2nd example, the 3rd example are embodiment, and the 4th example is a comparative example.
