Geocontainer treatment of drilling cuttings
Oil fields are sources of generation of large-capacity waste drilling cuttings. Drilling cuttings are characterized by a wide kind composition and high values of humidity – up to 98 % by weight. An effective method of drilling cuttings treatment using geocontainer processing is presented in this article. Geocontainer treatment combines sludge decantation and sludge hardening in a single processing unit. It is accompanied by the release of small-contaminated filtrate. Drilling cuttings treatment in geocontainer allows to reduce its moisture content up to 55…60 % by weight and to get material similar to soil (substitude for natural soil). Mathematical relationships of efficiency for drill cuttings dehydration are found out. It depends on the length of the residence time in the filter container.
