在海上钻井,随钻井液从井内出来的钻屑是一堆废物,如何处理这些废物,历来是国外钻井承包商感到棘手的问题。过去曾采用酸洗技术冲洗含油钻屑,然后倒人海中,但洗后钻屑中的残余化学成分达不到规定要求;也有些近海钻井平台将钻屑处理后运到陆地埋掉,这又不为环境保护条例所允许,问题仍难以解决。为保证海上油田开发对周围环境无害,国外研究 Drilling offshore at sea, drilling cuttings exiting the well with drilling fluids are a heap of waste and how trash disposal has traditionally been a problem that foreign drilling contractors find difficult. In the past, pickling technology was used to flush oil-bearing cuttings and then poured into the sea, but residual chemical content in the cuttings after washing did not meet the specified requirements. Some offshore drilling platforms handled drill cuttings and buried them on land, Not allowed by environmental protection regulations, the problem is still difficult to solve. In order to ensure that the development of offshore oilfields is harmless to the environment, foreign research
