Abstract
The utility model relates to a filter for an oilfield water injection well, and particularly relates to a wellhead high-pressure fine filtering treatment device. A primary filter of the device adopts a high-pressure fiber ball filtering core; a secondary filter adopts a sintering pipe filtering core; the primary filter is communicated with the secondary filter through a high-pressure pipeline; a communicating vale is installed on the high-pressure pipeline; the primary filter is connected with a pressure gage valve, a primary filter blow-down valve, a pipeline control valve and a back flushing charging valve respectively; the back flushing charging valve is connected with the secondary filter through a back flushing high-pressure hose and a high-pressure quick connector; the secondary filter is connected with a secondary filter blow-down valve and a control valve respectively; the control valve is connected with a valve and a water injection wellhead respectively; and the pipeline control valve is connected with a valve and a water inlet pipeline respectively. The filter realizes two-stage filtration, is high in filtration accuracy and large in pollutant containing capacity, also has a charging and back flushing function, and can realize filtering medium regeneration within a short time.
Description
Technical field:
The utility model relates to a kind of used for water injection wells in oil fields filter, particularly a kind of well head high pressure fine filtering treating apparatus.
Background technology:
At the production status of present water injection well, existing filter water environment capacity is little, and filtering accuracy is low, and the sewage backwash function is unsound, causes impurity to stop at filter course, and pressure increases filter course gradually and washed out, and impurity injects into well again.Because impurity constantly injects into well, cause the gambling plug, water injection pressure is increased year by year, multi-purpose station system pressure water filling difficulty causes individual well water filling augmented injection pump quantity constantly to increase, and forms vicious circle, production costs such as maintenance of machine expense, the electricity charge increase, and management difficulty strengthens, and flood effectiveness is undesirable.
The utility model content:
The technical problems to be solved in the utility model provides a kind of well head high pressure fine filtering treating apparatus, and this device has realized that double-filtration, filtering accuracy height, pollutant holding capability are big, has designed the anti-cleaning function of qi of chong channel ascending adversely simultaneously, can realize media regeneration in the short time.It is little to have overcome existing filter water environment capacity, and filtering accuracy is low, the unsound deficiency of sewage backwash function.
Technical solution adopted in the utility model is: a kind of well head high pressure fine filtering treating apparatus comprises grade one filter and secondary filter; Grade one filter adopts high pressure fibrous nodules filter core, secondary filter adopts the sintered pipes filter core, be connected by high pressure line between grade one filter and the secondary filter, on this high pressure line, install and be communicated with valve, grade one filter respectively with the Pressure gauge valve, the grade one filter blowoff valve, the pipeline control valve door is connected with the backwash charge valve, the backwash charge valve is connected with secondary filter by backwash high pressure flexible pipe and high-voltage quick joint, secondary filter is connected with by-pass valve control with the secondary filter blowoff valve respectively, by-pass valve control is connected with water injection well with valve respectively, the pipeline control valve door respectively with valve with come water pipeline to be connected.
The beneficial effects of the utility model are: the utility model is owing to adopted double-filtration and the anti-cleaning structure of design qi of chong channel ascending adversely, thereby have the filtering accuracy height, pollutant holding capability is big and can realizes the advantage of media regeneration in the short time, improved the filter element life cycle more than 10 times, simple to operate, reduce cost.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, a kind of well head high pressure fine filtering treating apparatus comprises grade one filter 1 and secondary filter 2; Grade one filter 1 adopts high pressure fibrous nodules filter core, secondary filter 2 adopts the sintered pipes filter core, be connected by high pressure line between grade one filter 1 and the secondary filter 2, on this high pressure line, install and be communicated with valve 5, grade one filter 1 respectively with Pressure gauge valve 10, grade one filter blowoff valve 9, pipeline control valve door 8 is connected with backwash charge valve 3, backwash charge valve 3 is connected with secondary filter 2 by backwash high pressure flexible pipe and high-voltage quick joint, secondary filter 2 is connected with by-pass valve control 6 with secondary filter blowoff valve 4 respectively, by-pass valve control 6 is connected with water injection well 12 with valve 7 respectively, pipeline control valve door 8 respectively with valve 7 with come water pipeline 11 to be connected.
Be understandable that, more than about specific descriptions of the present utility model, only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
