Description
Technical field
The utility model relates to crude oil oily water separation technique field, espespecially a kind of offshore oilfield crude oil profit treating apparatus.
Background technology
In oil recovery process, the crude oil of extraction often contains a large amount of water, and oil and water form stable emulsion. Simultaneously, in oil water mixture, contain a large amount of SSs and silt, make emulsion more stable, and make water-oil separating become difficulty, simultaneously serious to equipment attrition, as adopt the existing oil-gas-water treating system in oil field to process it, and easily cause the problems such as treatment system cannot normally be worked, crude oil water content is not up to standard, affect oil sale price and economic benefit.
There is more ripe treatment technology in oil field, land at present, is mainly to adopt chemical agents such as adding demulsifier, under the condition of heating, destroys emulsion, realizes water-oil separating. But the equipment in oil field, land and technology conventionally need the processing unit of significant volume and reach the processing time of tens of hours, can not adapt to offshore platform equipment and take up an area the condition that space is little, the processing time is short, energy consumption of device for processing is limited.
Utility model content
The purpose of this utility model is to provide a kind of offshore oilfield crude oil profit treating apparatus, and it is simple in structure, and floor space is little, and treatment effeciency is high, can adapt to offshore platform operating condition.
To achieve these goals, technical solution of the present utility model is: a kind of offshore oilfield crude oil profit treating apparatus, comprising efficient cyclone, the inlet of described efficient cyclone is connected with feed tube, the oil drain out of described efficient cyclone is communicated with the import of pipe-line mixer by first row oil pipe, the import of described pipe-line mixer is respectively by pipeline and demulsifier chemicals dosing plant, sulfur elimination chemicals dosing plant is communicated with, the outlet of described pipe-line mixer is communicated with the inlet of free water knockout (FWKO), between the inlet of the oil-out of described free water knockout (FWKO) and high speed three-phase separator, be connected flowline, on described flowline by being connected with oil pump and senior strengthening emulsion breaker after forward direction, the oil drain out of described free water knockout (FWKO) passes through second row oil pipe to closed tank platoon, described second row oil pipe is communicated with high speed three-phase separator.
Further, the mud discharging mouth of described high speed three-phase separator is by the first discharge pipeline to spoil disposal case, and described the first discharge pipeline is provided with conveying worm.
Further, the water return outlet of described free water knockout (FWKO) is communicated with the inlet of efficient cyclone by return water pipe, and described return water pipe is provided with end water pump.
Adopt after such scheme, the beneficial effect of the utility model offshore oilfield crude oil profit treating apparatus is: the utility model is by the skid-mounted device structure of senior strengthening emulsion breaker and the combination of high speed three-phase separator, it is simple in structure, floor space is little, treatment effeciency is high, offshore platform operating condition be can adapt to, lifting and transport are easy to.
Brief description of the drawings
Fig. 1 is the flowage structure schematic diagram of the utility model offshore oilfield crude oil profit treating apparatus.
Below in conjunction with accompanying drawing, by embodiment, the utility model is described further;
Detailed description of the invention
Shown in Fig. 1, the utility model offshore oilfield crude oil profit treating apparatus comprises efficient cyclone 1, the inlet of efficient cyclone 1 is connected with feed tube 2, the oil drain out of efficient cyclone 1 is communicated with the import of pipe-line mixer 4 by first row oil pipe 3, the import of pipe-line mixer 4 is communicated with demulsifier chemicals dosing plant 5 and sulfur elimination chemicals dosing plant 6 by pipeline respectively, in demulsifier chemicals dosing plant 5, be placed with demulsifier herein, in sulfur elimination chemicals dosing plant 6, be placed with sulfur elimination. The outlet of pipe-line mixer 4 is communicated with the inlet of free water knockout (FWKO) 7, between the inlet of the oil-out of free water knockout (FWKO) 7 and high speed three-phase separator 8, be connected flowline 9, on flowline 9 by being connected with oil pump 10 and senior strengthening emulsion breaker 11 after forward direction, the oil drain out of free water knockout (FWKO) 7 is by second row oil pipe 12 to closed tank platoon, and second row oil pipe 12 is communicated with high speed three-phase separator 8. The mud discharging mouth of high speed three-phase separator 8 is by the first discharge pipeline 13 to spoil disposal case, and the first discharge pipeline 13 is provided with conveying worm 14. The water return outlet of free water knockout (FWKO) 7 is communicated with the inlet of efficient cyclone 1 by return water pipe 15, and return water pipe 15 is provided with end water pump 16.
When work, by the moisture mud crude oil that contains from efficient cyclone 1 isolated preliminary breaking emulsion and dewatering, after demulsifier chemicals dosing plant 5, sulfur elimination chemicals dosing plant 6, pipe-line mixer 4 dosings, entering free water knockout (FWKO) 7 further dewaters, the water of deviating from is returned efficient cyclone 1 through end water pump 16 and is again processed, fuel-displacedly be introduced in senior strengthening emulsion breaker 11 through oil pump 10, temperature remains on 30～80 DEG C, the time of staying is 1～20 minute, enter afterwards in high speed three-phase separator 8, the time of staying is 1～20 minute, final dewatering, desliming. Oil extraction, by the overbottom pressure of high speed three-phase separator 8, is entered oil platform closed tank platoon. Spoil disposal is transported to spoil disposal case by conveying worm 14. Draining utilizes the overbottom pressure of high speed three-phase separator 8, transports to free water knockout (FWKO) 7 and again processes.
The above embodiment is described preferred embodiment of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model, all should fall in the definite protection domain of claims of the present utility model.
