Abstract
The present invention relates to an oil field technique for dissolving salt and paraffin without pushing down production and an equipment thereof. In the skid-mounted technique for dissolving salt and paraffin without pushing down production, water for dissolving salt and paraffin is heated to 90 DEG C to 100 DEG C, and pumped into an oil well sleeve by an adjustable plunger pump adjusted according to the delivery capacity of an oil well pump. The skid-mounted equipment for dissolving salt and paraffin without pushing down production comprises a water tank, a heater, a plunger pump and a frequency transformer. The water tank is connected with the heater, the heater is communicated with the plunger pump, the plunger pump is connected with the oil well sleeve, and a power supply is communicated with the plunger pump by the frequency transformer. The present invention provides a novel simple and practical technical process for dissolving salt and paraffin. The present invention has the advantages of energy saving, environmental protection, low investment cost, no reduction in oil well production and no influence on the normal production of the oil well.
Description
Technical field:
The present invention relates to oil field salinization ceroplastic and equipment.
Background technology:
At present, oil well salinization wax adopts following several technologies, but there are some technology limitations in these processes.
Pouring water of cementing truck salinization ceroplastic is applicable to and adapts to all oil wells, but it is serious to cut down output, and moisture convalescence reaches 3～5 days.
Little discharge capacity (the 2m of elevated tank
3About/h) pouring water salinization ceroplastic is applicable to the salt crust paraffin-troubled well of no sleeve pipe gas, but need guard and huge wellsite facility, comprising: water supply well, water tank, electrical heating, room on duty.And the little discharge capacity (2m of elevated tank
3About/h) pouring water salinization ceroplastic individual well will use a set of equipment, the waste resource, input expense height, the operating cost height does not have application value.
BZF-3 skid-mounted type oil well is multi-functional to be applicable to continuous production fluid, day liquid measure at the waxing in production well of 8-25 ton from washing ceroplastic, but wax removal is not thorough, can't discharge the pit shaft foul, is not suitable for the salt crust well.
Add efficient flushing fluid ceroplastic and be applicable to day produce oil more than 3 tons, day production fluid is at the paraffin-troubled well below 10 tons, and is high but cost drops into, every well adds dose at the 500-1000 kilogram, every month 1-2 time, and serious for wax deposition, also to periodically be aided with pouring water of cementing truck ceroplastic.
Add and press down the salt crust well that the anti-salt holddown technology of salt agent is adapted to free water, but cost drops into high, every well adds dose 200-300 kilogram, owing to there is not continuous dosing technology, medicament is discharged fast with recovered water, the medicament waste, cause period of validity only to be 1-3 days, but the technology of current anti-salt holddown is to irritate hydratable salt, to be aided with the salt agent, be the anti-salt holddown technologies of single means to press down the salt agent merely at present, do not appear in the newspapers at home.
By the comparative analysis of above The field technology, oil well salinization ceroplastic mainly is to rely on cementing truck to irritate hot water at present, and water supply volume is 6～11m
3, discharge capacity is 6～12m
3, general moisture convalescence reaches 3～5 days.Therefore, improve existingization salinization ceroplastic, rate had remarkable economical value when the raising oil well was effectively produced.
Summary of the invention:
Purpose of the present invention is exactly the novel technique of change salinization wax that will be simple and practical, also has energy-conserving and environment-protective simultaneously, and input cost is cheap, and oil well is not cut down output, and does not influence the oil well ordinary production.
The object of the present invention is achieved like this:
The skid-mounted type salinization wax technology of not cutting down output will be changed salinization wax water and be heated to 90-100 ℃, by the regulating plunger pump of adjusting according to the oil pumping pump delivery, will change salinization wax water injection oil well casing.
Be used for the do not cut down output skid-mounted type salinization wax equipment of technology of described skid-mounted type salinization wax, comprise water tank, heater, plunger displacement pump, frequency conversion instrument, water tank is connected with heater, and heater is communicated with plunger displacement pump, plunger displacement pump is connected with oil well casing, and power supply is connected through frequency conversion instrument and plunger displacement pump.
Advantage of the present invention:
1, all devices is integrated on the work car;
2, pour water by the discharge capacity of pouring water of oil reservoir district well-flushing charter design, can not cause and cut down output and influence the ordinary production of oil well.
3, mobility strong;
4, can be self-powered, when pouring water, need not stop well and connect electricity, avoided increasing the cooperating amount in oil reservoir district, avoided simultaneously connecing electricity and causing the salt holddown because of stopping well;
5, do not need to add chemical agent, can effectively protect environment.

Specific embodiment
To change salinization wax water and be heated to 95 ℃,, will change salinization wax water and inject oil well casing by the regulating plunger pump of adjusting according to the oil pumping pump delivery.
It is as follows to calculate the oil well pump theoretical displacement with main pump type in scene and main operational factor:
The 32mm oil well pump, press stroke 4.8m, jig frequency is calculated for 2～4 times, day theoretical displacement 10.94～21.88m
3, discharge capacity 0.45mm～0.90m per hour
3
The 38mm oil well pump is pressed stroke 4.8m, and jig frequency is calculated for 2～4 times, day theoretical displacement 15.74～31.48m
3, discharge capacity 0.6～1.30m per hour
3
Comprehensive above oil well pump theoretical displacement and at present the scene with the little discharge capacity (2m of elevated tank
3About/h) pouring water salinization ceroplastic operation discharge capacity, the skid-mounted type salinization wax of the pouring water technology of not cutting down output is 3.0m with plunger displacement pump theoretical displacement choosing value
3/ h, after discharge capacity control, the work discharge capacity is at 1.2～3.0m
3Adjustable between the/h.
Skid-mounted type salinization wax equipment comprises water tank, heater, plunger displacement pump, frequency conversion instrument, generator, and water tank is connected with heater, and heater is communicated with plunger displacement pump, and plunger displacement pump is connected with oil well casing, and generator is connected through frequency conversion instrument and plunger displacement pump.
By the stepless adjustment of the frequency conversion instrument discharge capacity of pouring water, realized the approximate equilibrium of discharge capacity and oil well pump discharge water of pouring water, thereby guaranteed not cut down output from technology.
Should be noted that at last: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present invention; And not breaking away from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope that the present invention asks for protection.
