Abstract
The invention relates to a chrome leather shavings well-drilling leakage-stopping material which comprises the following components in parts by weight: 40-100 parts of chrome leather shavings and 5-60 parts of addition agent. A preparation method of the material comprises the following steps of: evenly mixing the chrome leather shavings with the addition agent, so that the particle size of 400-100 meshes is prepared, i.e. a finished leakage-stopping agent is obtained. The leakage-stopping material takes the chrome leather shavings as a main raw material, the chrome leather shavings itself is a protein fiber-shaped material, the protein fiber is good in stability after the chrome is kneaded, and the protein fiber can be taken as common polysaccharide fiber in the normal leakage-stopping agent. The solid waste in the leather production industry is used for stopping the leakage of an oil well, so that the material is good in effect and is low in cost, the environmental pollution is reduced, an ideal method for treating the solid waste in the leather production industry is provided, and the leather production industry is environment-friendly and durable in development.
Description
Technical field
The invention belongs to petrochemical industry, relate to drilling well, especially a kind of chrome leather shavings well-drilling leakage-stopping material.
Background technology
Leakage refers in the various borehole operation processes such as drilling well, well cementation, test or well workover, various working fluids (comprising drilling fluid, grout, well finishing liquid and other working fluid etc.) bleed the stratum under differential pressure action phenomenon.According to statistics, whole world leakage incidence accounts for 20%～25% of drilling well sum, and the processing of leakage is difficult point and indispensable technology in petroleum drilling.Plugging agent fibre composition commonly used mainly contains lumber fibre, mineral fibre, glass fibre, textile fibres, bagasse, beet pulp etc. at present, and coordinates some particulate materials to use.
Shavings has the fiber characteristics, good toughness, intensity are high, and the tanning of process chromium ion, hydrolytic resistance significantly improves, and certainly as crude substance, to the stratum without injury, suspension is good in mud, can pull an oar into different-grain diameter, and main component cement and the kaolin compatibleness of chromium ion wherein and drilling fluid mud are good, not affecting its performance, is the more satisfactory material of leak stopping.Contain the chromium leather-solid waste and chrome shavinge is tannery, because containing chromium metal, be commonly considered as one of Leather-Industrial Pollution source, calculate by its weight, account for 60% left and right of leather gross weight, as untimely processing with take full advantage of, be the maximum waste to resource, will cause severe contamination to environment simultaneously.Therefore, chrome shavinge due to the oilwell drilling leak stopping, is not only made rational use of resources, environmental contamination reduction, be the good project that is worthy to be popularized simultaneously.
By retrieval, not yet find to adopt chrome shavinge as the publication document of plugging agent.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of chrome leather shavings well-drilling leakage-stopping material is provided, this material is with the solid waste of leather industry---and chrome shavinge is as the drilling leakage blockage material, and not only plugging effect is good, and the science environmental protection.
For solving the problems of the technologies described above, the present invention adopts following technical proposal:
A kind of chrome leather shavings well-drilling leakage-stopping material, patching materials consists of and parts by weight are respectively:
Chrome shavinge 40-100
Auxiliary agent 5-60.
And described auxiliary agent is one of them kind of calcium carbonate, diatomite, oil-soluble resin or polyacrylamide.
Advantage of the present invention and positively effect are:
1, this patching materials is take chrome shavinge as main raw, and chrome shavinge is rubbed owing to having passed through chromium from as thiozell shape material, and the thiozell good stability can play the effect of general polysaccharides fiber in conventional plugging agent.
2, this patching materials adopts the leather industry solid waste to be used for the oil well leak stopping, not only effective, cost is low, environmental contamination reduction, and for the leather industry solid waste has found desirable outlet, can make leather industry realize environmental friendliness and Sustainable development.
