Problems solved by technology
At present, no suitable drilling fluid waste treatment equipment has been developed in China. Land drilling operations in various oil fields generally use methods such as solidification, dumping, landfilling, incineration or centralized stacking, and natural weathering to treat waste drilling mud. Fundamentally eliminate the pollution caused by oilfield drilling waste to the environment. After long-term storage, it will be leached into the ground by rainwater, which will cause serious pollution to the surrounding soil, vegetation, and surface water. At the same time, the drilling fluid has not been recycled. waste of drilling fluid
Therefore, these treatments do not promote the use of

The invention discloses a processing technology of well drilling wastes, which comprises the steps that at the S1 step, one end of a well mouth is connected to an entrance end of a solid control vibration screen, and the other end of the well mouth is connected to a circulating tank; at the step S2, waste drilling chips generated in well drilling operations are processed; at the step S3, waste mud generated in the well drilling operations is processed; at the step S4, waste mud generated after the well drilling operations is processed; and at the step S5, a curing agent is added into a stirring machine, wherein rock chips B, rock chips C, rock chips D and the curing agent are mixed by stirring of the stirring machine, and the stirred mixture is conveyed by a conveying machine I into a brick press and then made into mold bricks. The processing technology of the well drilling wastes disclosed by the invention is beneficial in that the well drilling wastes can be fully circulated and utilized, and the processing technology is economic, environment-friendly and low in operation cost.
Description
technical field [0001] The invention relates to the technical field of waste mud generated after drilling and completion, waste mud during drilling operations, and waste cuttings generated during drilling operations, in particular to a processing technology for drilling waste. Background technique [0002] In the drilling process of oil and gas exploration and development, a large amount of waste is inevitably produced, forming potential pollution to the environment. Waste drilling mud is one of the main sources of pollution in the process of oilfield exploration and development. It is a kind of clay, heavy metal materials, various A multiphase stable colloidal suspension system of chemical treatment agents, sewage, polluted oil and drilling cuttings. At present, no suitable drilling fluid waste treatment equipment has been developed in China. Land drilling operations in various oil fields generally use methods such as solidification, dumping, landfilling, incineration or ce...
