Description

technical field [0001] The invention relates to the technical field of petroleum equipment, in particular to chemical heat washing process equipment and a treatment process for oilfield waste heavy oil sludge. Background technique [0002] In this field, the main problems are that the construction period of the station is long, the treatment of waste is not thorough enough, and it cannot be migrated with the change of the drilling block, which causes the waste to be transported to a longer distance, increases the transportation cost, prolongs the processing time period, and cannot meet the needs of drilling. Requirements for production relocation. [0003] Disadvantages of WD treatment for a single well: the treatment volume is not concentrated enough, and the WD equipment cannot fully exert its performance, which leads to high unilateral cost of waste treatment and puts pressure on drilling production costs. Contents of the invention [0004] Aiming at the deficiencies i...

Problems solved by technology

[0002] In this field, the main problems are that the construction period of the station is long, the treatment of waste is not thorough enough, and it cannot be migrated with the change of the drilling block, which causes the waste to be transported to a longer distance, increases the transportation cost, prolongs the processing time period, and cannot meet the needs of drilling. Requirements for production relocation

[0003] Disadvantages of treatment while drilling for a single well: the treatment volume is not concentrated enough, and the treatment equipment while drilling cannot give full play to its performance, resulting in high unilateral cost of waste treatment, which puts pressure on drilling production costs
