对废弃泥浆固液分离后固相物资源化利用进行可行性研究：将20%—30%的固化剂(体积)、6%—10%的骨料(黏土和砂子、石屑或碎石、矿渣等),425^#普通硅酸盐水泥掺入10%;促凝剂3%—5%加入固相物搅拌后,可直接用于边坡加固或场地硬化,也可通过搅拌挤压后制成免烧砖,用于井场围墙、生活区和井非承重承压区建设。对制成的免烧砖的建筑性能和环保指标进行分析确定其符合标准要求。从效益角度分析,此方法改变了勘探过程中传统钻井废弃物的处理方式,实现了钻井液废弃物减量化、无害化、资源化的循环利用,以消除石油天然气勘探过程中的环境风险。

Based on the solid liquid separation of solid phase waste drilling mud, the resource utilization feasibility study is conducted. 20%-30% of the curing agent (by volume), 6%-10% of the aggregate (clay and sand, stone chips or gravel, slag, etc), 425^# ordinary Portland cement mixed with 10%, coagulant 3%-5% by adding the solid phase materials, after mixing, they can be directly used for the slope reinforcement or the site hardening. With a stir squeeze system, they can also be turned into non-fired brick for the walls of the well site, the living area and wells in non-load-bearing confined zones. The buildings made of non-fired brick and the related environmental indicators are analyzed against the standard requirements. From the effectiveness point of view, this method has changed the traditional way of drilling waste disposal in the exploration process, the waste drilling fluid waste is reduced and made harmless, the resource is recycled, and the environmental risks are eliminated in the oil and gas exploration process.
