油基钻井岩屑尾渣制备压裂支撑剂研究进展
Research progress on preparation of fracturing proppant using oil-based drilling cuttings residue
油基钻屑制备压裂支撑剂是实现含油固体废物资源化利用的重要方向,对缓解油气钻井和储层改造中的成本与环保压力具有重要意义。系统概括与分析了油基钻屑预处理、油基钻屑烧结制备支撑剂、油基钻屑免烧制备支撑剂和树脂覆膜制备支撑剂的研究现状。研究表明将油基钻屑与铝矾土、二氧化锰、水泥和其他添加剂在适宜配比下混合并通过高温烧结或免烧等方式可制备出整体性能基本满足行业标准要求的支撑剂,但仍存在油基钻屑掺入率低(平均<30%)、支撑剂抗压强度不高(≤52 MPa)等问题,需从支撑剂制备核心添加材料与配方组成、制备工艺与设备等方面持续开展研究和攻关。相关分析可为油基钻屑的高效资源化利用与高强度压裂支撑剂制备的有机结合提供重要依据。
The preparation of fracturing proppant using oil-based drilling cuttings is an important direction to realize the resource utilization of oily solid waste,which is of great significance to alleviate the cost and environmental protection pressure in oil and gas drilling and reservoir stimulation.This paper systematically summarizes and analyzes the research status of oil-based drilling cuttings pretreatment,oil-based drilling cuttings sintering to prepare proppants,oil-based drilling cuttings non-burning to prepare proppants,and resin coating to prepare proppants.It is shown that,mixing with bauxite,manganese dioxide,cement and other additives under appropriate proportions and sintering at high temperature or non-burning,the oil-based drilling cuttings can be used to prepare proppants whose overall performance basically meets the requirements of industry standards.However,there are still challenges such as low oil-based drilling cuttings incorporation rate (average <30%) and low compressive strength of proppants (≤52 MPa).It is necessary to continue to carry out research from the aspects of core additive materials and formula composition,preparation process and equipment for proppant preparation.The correlation analysis can provide an important basis for the efficient resource utilization of oil-based drilling cuttings and the organic combination of high-strength fracturing proppant preparation.
