聚磺钻井液岩屑随钻治理固化剂的室内研究

Laboratory Study of curing agent for polysulfonate drilling fluid cuttings treatment while drilling

随着新环保法的出台及环境保护要求提高,油田勘探开发要求钻井必须开展钻井液岩屑不落地治理,不允许洒落地面或挖泥浆池,造成环境污染。聚磺钻井液岩屑是钻井过程中伴随钻井液产生的废弃物,粘附钻井液材料,使CODcr、pH值,石油类、重金属等环境污染指标偏高,亟待解决。聚磺钻井液岩屑随钻治理固化剂可将废弃钻井液、岩屑中的有害成分封闭、包裹在固相中,通过物理、化学变化,从而达到限制岩屑中有害物质迁移扩散的目的。

According to new environment laws,drilling fluid cuttings are no longer allowed to treat out of the requirements ofthese laws.So,this paper researches the curing agent for polysulfonate drilling fluid cuttings treatment while drilling in laboratory.
