Description

Combined skid-mounted oilfield water treatment equipment Technical Field The invention relates to the technical field of oilfield produced water treatment equipment, in particular to combined skid-mounted oilfield water treatment equipment. Background During oilfield exploitation, a large amount of produced water is produced, and the sewage must be effectively treated to be reinjected into the stratum or discharged after reaching standards. The conventional oilfield water treatment station generally adopts a construction mode of a reinforced concrete structure, and has the following remarkable defects: 1. the construction period is long, the civil construction, equipment installation and pipeline laying take months or even years, and the requirement of quick production in the oil field cannot be met. 2. The investment cost is high, the field construction engineering amount is large, the investment of manpower and material resources is large, and the investment is greatly influenced by regions and climates. 3. The flexibility is poor, and the fixed structure can not be moved. When the exploitation of a certain oil field block is finished or the water quantity is changed, the treatment facilities are abandoned, so that the resource waste is caused. 4. The maintenance and the upgrading are difficult, the equipment layout is fixed, the space is compact, and the maintenance, the replacement or the process upgrading and the transformation of the core component are very inconvenient. In the prior art, although there is a single skid-mounted device, such as a skid-mounted filter or a dosing device, they are generally single in function and do not solve all the problems from the perspective of the entire treatment system. How to integrate the whole water treatment system (such as units for removing oil, suspended matters, silicon, softening and the like) with high degree and meet the requirements of quick deployment, flexible allocation and convenient maintenance at the same time is a technical problem to be solved in the field. Disclosure of Invention The invention aims to solve the technical problem of providing a combined skid-mounted oilfield water treatment device aiming at the defects of the prior art. The technical scheme includes that the combined skid-mounted oilfield water treatment equipment comprises at least one core treatment skid for mounting at least one of a cyclone oil remover, an air flotation machine, a filtering module, a softening device and a membrane treatment system, at least one auxiliary system skid for mounting at least one of a medicine adding system, a power system, a control system and a meter monitoring system and a detachable connecting mechanism, wherein the core treatment skid is connected with the auxiliary system skid through the connecting mechanism, the connecting mechanism is structurally and quickly connected with a flange and an integrated electric/liquid plug interface, the cyclone oil remover is connected with the air flotation machine, the filtering module is connected with the softening device, the softening device is connected with the membrane treatment system, the medicine adding system is respectively connected with the cyclone oil remover, the air flotation machine, the filtering module and the softening device, the power system is respectively connected with the cyclone oil remover, the air flotation machine, the filtering module, the softening device and the membrane treatment system, the control system is respectively connected with the medicine adding system, the power system and the meter monitoring system, and the medicine adding system is connected with the medicine adding system. The technical scheme has the beneficial effects that the modularized and skid-mounted oilfield water treatment equipment is adopted, so that the oilfield water treatment equipment is rapidly deployed, flexibly transported and conveniently maintained. The skid blocks can be reused conveniently, and the construction period is shortened. Different functional prying blocks can be flexibly selected and combined according to the water quality characteristics and treatment scales of different oil fields.
