由于实施移动钻井项目每年将要产生超过 ９００００ ｂｂｌ的钻井废弃物，ＴＨＵＭＳ公司在加利福尼亚Ｗｉｌｍｉｎｇｔｏｎ油田的ＬｏｎｇＢｅａｃｈ地区每年需要花费＄３５０ ×１０４费用用于固体废弃物的脱水并船运到岸上进行上地填埋处理。１９９４年，ＴＨＵＭＳ公司执行了一项有关环境安全、经济的长期方案，用水力压裂法处理现场钻井泥浆、岩屑和油罐底泥。通过这种方式把钻井废物重新注入井下，这样就消除了运输及处理废弃物的主要成本。本文回顾了经调整可行的处理工艺，详述了汪入层的评估、注入开的选择、压裂控制及偏差井的地震监测；以及３年一个周期处理１００×１０４ｂｂｌ泥浆的设备．注入历史及经济性。
Because drilling mobile projects are expected to generate more than 90,000 bbl of drilling waste each year, THUMS costs $ 350x104 annually in Long Beach, Wilmington Field, California, for solid waste dewatering and ship ashore landfill deal with. In 1994, THUMS implemented a long-term program on environmental safety and economy that used hydraulic fracturing to treat on-site drilling muds, cuttings and tank bottoms. In this way, drilling waste is reinjected downhole, thus eliminating the major costs of transporting and disposing of the waste. In this paper, we reviewed the feasible and feasible treatment process, described the evaluation of Wangzhu layer, injection selection, fracturing control and seismic monitoring of deviation well; and the equipment for processing 100 × 104bbl mud in three years and one cycle. Inject history and economy.
