Abstract
The utility model discloses an oil well wax removing control device, which comprises a sleeve whose one end is connected with an oil delivery pipeline, the other end of the sleeve is connected with anoil pipe, the device further comprises a pipeline, a drug feeding control valve a, a drug feeding device, a drug feeding control valve b, a drug feeding piezometer and a delivery valve are orderly arranged on the pipeline, and the part between the drug feeding piezometer and the delivery valve on the pipeline is communicated with the sleeve. After the oil well wax removing control device is adopted, the wax removing is complete, the wax removing pump detecting period is long, the usage of wax removing agent is easily controlled, and the cost is low.
Description
Technical field
The utility model belongs to the oil equipment technical field, relates to a kind of paraffin removal from oil well control device.
Background technology
Under the normal temperature and pressure, paraffin is solid-state, but under underground HTHP, it is only the flowable of liquid state.Under normal temperature and certain pressure, keep the paraffin that flows always, just can not solidify, but when lose pressure, just can in pipeline, solidify gradually gradually, make pipeline clog.In the process of exploitation, the variation of pressure has reduced the solubility of paraffin in crude oil, and paraffin begins crystallization and finally on the inwall attached to the surface of production equipment and petroleum pipeline.
The paraffin removal unit that existing oil field is used all is by pipeline paraffin remover directly to be fed in the annular space to the sleeve pipe, and then through oil well pump paraffin remover is pumped in the oil pipe, removes the wax on the tube inner wall, reaches wax control purpose clearly.The shortcoming of doing like this is that wax removal is not thorough, and the wax removal pump detection period is short, and the bad control of the consumption of paraffin remover, and cost is bigger.
Summary of the invention
The purpose of this utility model provides a kind of paraffin removal from oil well control device, and clear cured thorough, clear cured pump detection period is long, and controls clear cured dose consumption easily, and cost is low.
The technical scheme that the utility model adopted is, a kind of paraffin removal from oil well control device, the sleeve pipe that one end is connected with oil pipeline, the other end of sleeve pipe is connected with oil pipe, also comprise a pipeline, be disposed with dosing by-pass valve control a, chemicals dosing plant, dosing by-pass valve control b, dosing pressure meter and drain tap on the pipeline, the dosing pressure meter is connected with sleeve pipe with part between the drain tap on the pipeline.
The beneficial effects of the utility model are:
1. the characteristics big at the oilfield scale, that oil well disperses have accomplished that cleaning capacity is strong, and compliance is strong, and low cost is easy to operate, easy care.
2. use the utility model wax removal control device, prolonged pump detection period, reached the purpose of clear wax control, and reduced traditional wax removal mode to oil casing, particularly to the injury on stratum.Prolonged the useful life of oil jacket.
3. joint props up consumption reduction.Reduced paraffin remover usage quantity, reduced cost of production.
Description of drawings
Fig. 1 is the structural representation of the utility model paraffin removal from oil well control device.
Among the figure, 1. dosing by-pass valve control a, 2. chemicals dosing plant, 3. dosing by-pass valve control b, 4. dosing pressure meter, 5. oil pipe, 6. drain tap, 7. sleeve pipe, 8. pipeline.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The structure of the clear cured control device of the utility model oil well as shown in Figure 1, comprise the sleeve pipe 7 that an end is connected with oil pipeline, the other end of sleeve pipe 7 is connected with oil pipe 5, also comprise a pipeline 8, be disposed with dosing by-pass valve control a1, chemicals dosing plant 2, dosing by-pass valve control b3, dosing pressure meter 4 and drain tap 6 on the pipeline 8, dosing pressure meter 4 is connected with sleeve pipe 7 with part between the drain tap 6 on the pipeline 8.
In the utility model wax removal control device,
The effect of dosing by-pass valve control a1 is: prevent that the gas effect from outflowing paraffin remover.
The effect of dosing by-pass valve control b3 is: the flow of control paraffin remover flow and water.
The effect of chemicals dosing plant 2 is: the container of dress paraffin remover.
The effect of dosing pressure meter 4 is: control wax removal control device pressure inside, when the device internal air pressure is excessive, have only by pressure release just to make the paraffin remover of adding or water enter into sleeve pipe 7.Control the switch of drain tap 6 by the reading of dosing pressure meter 4.
The effect of drain tap 6 is: decompression exhaust.
The work of the utility model paraffin removal from oil well control device was divided into for three steps:
1, adds quantitative clear water: close dosing by-pass valve control b3, open dosing by-pass valve control a1, add quantitative clear water to dosing control device 2, close dosing by-pass valve control a1, open dosing by-pass valve control b3, make clear water all enter the annular space of sleeve pipe 7 inside, flow into the shaft bottom with certain flow.Its objective is, water is entered in the sleeve pipe 7, be attached with moisture, corrode the tube wall of sleeve pipe 7 in order in dosing, to avoid medicine at sleeve pipe 7 inwalls.
2, add quantitative medicament: close dosing by-pass valve control b3, open dosing by-pass valve control a1, add quantitative clear cured dose to dosing control device 2, close dosing by-pass valve control a1, open dosing by-pass valve control b3, make medicament all enter the annular space of sleeve pipe 7 inside, flow into the shaft bottom with certain flow.
3, add quantitative clear water: close dosing by-pass valve control b3, open dosing by-pass valve control a1, add quantitative clear water to dosing control device 2, close dosing by-pass valve control a1, open dosing by-pass valve control b3, make clear water all enter the annular space of sleeve pipe 7 inside, flow into the shaft bottom with certain flow.Medicament mixes with pit shaft liquid after entering the shaft bottom, through oil well pump suction oil pipe 5, until being evacuated to ground.So just fully paraffin remover is punched into the shaft bottom, makes full use of.
Prolong pump detection period in the clear cured control device of the utility model oil well, greatly reduced maintenance cost, and reduced and add dose, reduced the oil well operating cost, improved the production timeliness.Concrete pump detection period with add the contrast of dose data and see Table 1:
Table 1: pump detection period with add dose data contrasts
