Oil well channeling sealing and leaking stoppage process based on coal-based solid waste composite cementing material
The invention discloses an oil well channeling and leaking stoppage process based on a coal-based solid waste composite cementing material, and relates to the technical field of solid waste resource utilization and green backfilling. The method at least comprises the following steps: S1, preparing a composite cementing material preparation system; s2, a pulping system; s3, a gas taking system; s4, a CO2 mineralization system; and S5, grouting a plugging system. According to the process, CO2 emission reduction, solid waste resource utilization and oil well plugging requirements are combined, and the coal-based solid waste composite cementing material slurry is prepared by utilizing the mineralization activity of coal-based solid waste and the cementing activity of a polymer gel material, so that cracks and gaps in an underground mining area of an oil field are effectively plugged; according to the technology, the recovery rate of crude oil in an oil well can be increased, the leakage risk of underground oil and gas resources passing through pores and cracks is effectively reduced, and an effective solution is provided for waste emission reduction and recycling in the coal power industry.
本发明公开了一种基于煤基固废复合胶凝材料的油井封窜堵漏工艺，涉及固废资源化利用和绿色回填技术领域。本发明至少包括以下步骤：S1：复合胶凝材料制备系统；S2：制浆系统；S3：取气系统；S4：CO2矿化系统；S5：注浆封堵系统。本发明工艺通过将CO2减排、固废资源化利用和油井封堵的需求相结合，利用煤基固废的矿化活性和高分子凝胶材料的胶凝活性，制备得到煤基固废复合胶凝材料浆液，进而对油田井下开采区域的裂缝、空隙进行有效封堵，这项技术不仅能够提高油井中原油的采收率，有效降低井下油气资源通过孔隙、裂缝的泄漏风险，而且为煤电行业的废物减排和循环利用提供一种有效的解决方案。
