Method for co-processing drilling cuttings in cement kiln
The invention relates to the field of waste treatment, and provides a method for co-processing drilling cuttings in a cement kiln, which comprises the following steps: firstly, separating a large amount of oil and gas in the drilling cuttings in a thermal cracking manner, and separating out wastewater to obtain waste oil with combustion value; crushing the rock debris slag, and grinding the crushed rock debris slag with other mineral raw materials in proportion to obtain a porous ceramic ball raw material; according to the method disclosed by the invention, not only is the well cuttings harmlessly treated, but also the well cuttings are cooperatively treated by using the cement kiln, so that less energy is consumed, the well cuttings are recycled to the maximum extent, and harmlessness, reduction and recycling of the well cuttings are fully realized.
本发明涉及废物处理领域，本发明提供了一种水泥窑协同处置钻井岩屑的方法，本方法首先采用热裂解的方式将钻井岩屑中大量的油气分离出来，并分离出废水，得到具有燃烧价值的废油，然后将岩屑渣粉碎后与其他矿物原料配比研磨成多孔陶瓷球原料；本发明的方法不但无害化处理钻井岩屑，而且使用水泥窑协同处置的方法，较少的消耗能源，最大限度的资源化利用钻井岩屑，充分实现钻井岩屑的无害化、减量化和资源化。
