在碳酸盐岩油气田上,压裂酸化是油气井投产和增产的有效措施。酸处理后,排出的残酸,含有若干有害物质的混有气体的液体。过去,对液、气基本上未进行分离,无控制地放喷,因而残酸随着天然气流飞溅,不仅使空气、农田、水塘、河流受到污染,而且对人、畜、农作物造成不同程度的损害。在目前暂无条件对残酸综合治理的情况下,采用了“残酸的分离与回注工艺”,可以有效地控制残酸的飞溅,大大减少残酸对环境的污染和对人、畜、农作物的伤害。我矿推广该
In carbonate oil and gas fields, fracturing and acidizing are effective measures for putting into operation and increasing production of oil and gas wells. Acid treatment, the discharge of residual acid, containing a number of harmful substances mixed with the gas liquid. In the past, the separation of liquid and gas was basically not controlled and the spray was released uncontrollably. As a result, the residual acid splashed along with the natural gas flow, which not only polluted the air, farmland, reservoirs and rivers, but also caused varying degrees of damage to people, livestock and crops The damage. In the current unconditional residual acid comprehensive management case, the use of “residual acid separation and injection process” can effectively control the residual acid splash, greatly reducing the residual acid pollution of the environment and to people, livestock, crops s damage. I mine to promote the
