Description

Oil gas water three phase separating bottle

Technical field

The utility model relates to a kind of oil gas water three phase separating bottle, specifically carries out oil gas water three phase separation for rock core end effluent in the indoor displacement test flow process of petroleum industry.Formation fluid is that solubilised state or free state are composed and be stored in stratum with oil gas water three kinds of phases by different proportion, indoor displacement test is to carried out with one or several solvents by the rock core of the saturated mistake of formation fluid must to the advanced row gas-liquid separation of rock core end effluent in displacement process, carry out water-oil separating again, the experimental datas such as oil recovery factor, moisture content, gas-oil ratio can be calculated to isolated oil, gas, water three-phase accurate-metering respectively, belong to conventional gas and oil experimental technique field.

Background technology

There is provided three phases separator to be generally used for well site in the market to produce, bulky, complex structure, is only applicable to large-scale production, is not suitable for laboratory experiment.Current laboratory experiment generally carries out phase separation with triangular flask, dry triangular flask after weighing is connected with rock core end, carry out gas-liquid separation, institute's receiver gases gas flowmeter measures, again the water-oil phase in triangular flask is weighed, generally survey by following two kinds of methods after obtaining water-oil phase gross mass and obtain oil, water two-phase quality separately, one is as petroleum ether dissolution crude oil with polar solvent, because there is profit density contrast, can settlement action be there is in the aqueous phase that relative density is larger, formed behind interface until profit and extract solvent and blends of crudes with syringe, remained aqueous phase is weighed, oil can be obtained, the respective quality of water two-phase.Shortcoming: operate comparatively difficulty when 1, extracting solvent and blends of crudes with syringe, cannot guarantee it all taken away and be not extracted into aqueous phase, human error factor is obvious.2, because forming solvent and blends of crudes, therefore earth's surface crude oil sample cannot be obtained, the data such as each hydrocarbon component of crude oil cannot be recorded.Two is when rock core end effluent range estimation moisture content is lower, with the moisture in the method removing sample of high temperature dehydration after obtaining water-oil phase gross mass, weighs and then obtain water-oil phase quality separately to the oil phase of remnants.Shortcoming: the oil component data causing recording of having volatilized of the light components in the earth's surface crude oil 1, after high temperature dehydration are imperfect.2, residue in triangular flask containing the aqueous phase of the certain salinity mineral matter that it dissolves after high temperature evaporation, survey oil phase quality and its true value has deviation.

Utility model content

The purpose of this utility model is to provide a kind of oil gas water three phase separating bottle, solve existing above-mentioned employing triangular flask and carry out gas-liquid separation, again to some deficiencies that the profit in triangular flask adopts two kinds of methods to survey to obtain the method for oil, water two-phase quality separately to exist, reduce human error by the utility model, be conducive to improving test mass and test data being accurately provided.

The purpose of this utility model is achieved through the following technical solutions, a kind of oil gas water three phase separating bottle, comprise the gas-liquid classification bottle stopper of inserting bottleneck, the inlet line inserted in gas-liquid classification bottle stopper and exhaust line, it is characterized in that, described separating bottle bottle is by be connected as a single entity and three parts communicated are formed, bottle top is like being triangle bottle and having scale, bottle bottom is cylindrical tube and has scale, skin plug is inserted in the end mouth of cylindrical tube, middle part be the descending transition part of top and the bottom diameter, and lower cylindrical shape cylindrical shell is inserted in the support of seemingly graduated cylinder shape.

The aspect ratio of described separating bottle upper, middle and lower three part is 7:2:9.

Bottle structure of the present utility model makes aqueous phase keep the difference being conducive to being read by bottle scale oil phase upper and lower liquid level during flow regime to obtain oil phase volume, the set temperature of baking oven makes oil phase keep flowing, because water-oil phase exists density contrast, the aqueous phase that density is larger can fall to bottom separating bottle, because keeping the not high impact on light components in crude oil of temperature of oil phase flowing to ignore, solving oil component and can not survey and survey incomplete problem.After draining, the cleaning of bottle wall is solved and be dissolved in the residual problem of aqueous phase mineral matter.The utility model is conducive to realizing easy and simple to handle to the accurate measurement of oil gas water three phase fluid.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

In figure, 1 inlet line, 2 gas-liquid separation bottle stoppers, 3 bottle tops, 4 volume markings, 5 skin plugs, 6 supports, 7 exhaust lines, 8 transition parts, 9 bottle bottoms.

Detailed description of the invention

Further illustrate the utility model in conjunction with the accompanying drawings and embodiments, as shown in Figure 1, the utility model comprises the gas-liquid classification bottle stopper 2 of inserting bottleneck, the inlet line 1 inserted in gas-liquid classification bottle stopper 2 and exhaust line, separating bottle bottle is by be connected as a single entity and three parts communicated are formed, bottle top 3 is like being triangle bottle and having scale, bottle bottom 9 is cylindrical tube and has scale, skin plug 5 is inserted in the end mouth of cylindrical tube, middle part be the descending transition part 8 of top and the bottom diameter, and lower cylindrical shape cylindrical shell is inserted in the support 6 of seemingly graduated cylinder shape.The aspect ratio of separating bottle upper, middle and lower three part is 7:2:9.

To weigh and the oil gas water three phase separating bottle of drying is connected with rock core end when experiment uses, rock core end effluent, after inlet line 1 enters bottle, measures because the discharge of gravitational differentiation gas enters in pre-set gas flowmeter through exhaust line 7.Oil, water two-phase enters after in bottle because now oil phase viscosity is larger, the reason oil of poor fluidity, the mutual Bao Rong of water two-phase not necessarily there will be oil-water interfaces, inlet line 1 is closed after empirically requiring to collect the oil water mixture of certain volume, read gas flow count value simultaneously, take off bottle to insert and keep in advance being formed after sharp interface until profit in the baking oven of uniform temperature taking out bottle, again bottle is inserted in normal temperature or low temperature environment to ensure that oil phase solidifies aqueous phase flowing, the difference reading the liquid level up and down of volume markings 4 oil phase records oil phase volume, light rolling bottle oil phase is not when flowing, transfer to the draining of skin plug 5, distilled water and absolute ethyl alcohol is used wall built-up residual water to be cleaned up respectively, after the drying of absolute ethyl alcohol nature Volatile bottle wall, the separating bottle leaving oil phase is weighed, calculate fuel-displaced respectively, water two-phase quality separately.Temperature in baking oven controls at 48-52 °.The temperature of low temperature environment controls at 23-27 °.Because keeping the not high impact on light components in crude oil of temperature of oil phase flowing to ignore, solving oil component and can not survey and survey incomplete problem.After draining, the cleaning of bottle wall is solved and be dissolved in the residual problem of aqueous phase mineral matter.
