Description
The utility model relates to a kind of down-hole steam quality, temperature sampling and testing instrument, genus downhole testing instrument class that is used for the oil field.
Along with the development of oil-field thick-oil development technique, heat extraction by steam injection has become an important means of thickened oil recovery, and annotates the fine or not heavy oil development that directly influences of vapour quality, and the utility model can be to any degree of depth in the well in the notes vapour scene, steam quality and temperature are tested, and then improve heat and annotate efficient.Thereby reduce the cost of production of heavy crude producing, increase the economic benefit of heavy crude producing, the utility model Chinese patent by retrieval is not reported.
The utility model purpose is a kind of down-hole steam quality, the temperature sampling and testing instrument that proposes in order to address the above problem.
The utility model is to realize like this.
The utility model is equipped with little spring 2 spacing jackscrew 4 lock balls and overlaps 5 lock balls 6 below bump sliding sleeve 1, connect an energy-stored spring that compresses 8 and upper sealing valve bar 9 again, center pull rod 19 and lower seal valve rod 22, the upper-lower seal valve rod is being controlled inlet end seal receptacle 11 and steam output end seal receptacle 20, in the process of going into the well, make saturated vapour admission open tube 10 with go out vapour open tube 23 constantly separates with saturated vapour in liquid phase constantly replace, after arriving sample point, gas is fully replaced and is finished, by the HTHP joint ring, saturated vapour is sealed in is equipped with in the probe tube 18 of central tube 16 and clamping wall pipe 17.Simultaneously, upper magnetic steel drives temperature survey assembly 28 and writes down the temperature of sample point at that time along with moving on the upper magnetic steel seat.
Operating principle of the present utility model: before the use, at first steel wire plug 3 is linked together with steel wire, the state that sampler is being opened, go into the well again, when down to the sample position, steam enters in the admission open tube 10 from sampler admission end seal receptacle 11, and the steam vent road of process central tube 16 enters sampler inside, because steam flow changes, most of steam gas phase flows out sampler from going out vapour open tube 23 through steam output end seal receptacle 20; Saturated vapour flow into clamping wall pipe 17 both sides through the liquid phase of separating, and the gas liquid phase is constantly assembled in probe tube, and the continuous again simultaneously spout hole from the clamping wall pipe inboard flows out sampler by central tube, thereby the assurance steam sample is replaced automatically.When sampling, with weight impinger bump sliding sleeve, when it is subjected to clashing into, shifting movement is taking place in sealed valve stem 22 under the effect of energy-stored spring, make the sealing of admission end seal receptacle 11 and steam output end seal receptacle 20 ducts, can reach the purpose of spot sampling, simultaneous temperature is measured assembly and is write down the temperature of point of destination at that time, obtains temperature value by the interpretation registration card; Obtain the steam quality value by the chemical analysis steam sample.
When using, earlier steel wire is passed the utility model bump sliding sleeve 1, accomplish fluently the steel wire knot with steel wire plug 3, then lock ball is put into lock ball cover position, at this moment, sampler is opened, again sampler is transferred from well head blowout prevention box, when transferring to the sample position, wait for a period of time, steam is fully replaced, transfer the weight of blowout prevention box then, weight and bump sliding sleeve are bumped against, and sealing admission end seal receptacle 11 and steam output end seal receptacle 20 make steam seal in probe tube under the effect of energy-stored spring, the temperature survey assembly of the bottom by sampler is recorded in the temperature of this target zone position.Understand steam quality and temperature by chemical examination and Card Reader.
Advantage of the present utility model, be to adopt the structure of collection sample tube and storage sample tube and joint ring bump head, make the steam sampling device can annotate in heavy oil wells in the well of vapour arbitrarily that the degree of depth is carried out the sample examination mass dryness fraction and Card Reader is understood temperature, its method is intuitively feasible, have annotating under the vapour situation the characteristics of down-hole any point random sampling, have downhole temperature mass dryness fraction test function simultaneously again, the utility model uses nimbly and freely, can increase work efficiency, thus the cost of production of reduction heavy crude producing.
