The underbalanced well drilling and logging detection sampling device comprises a sample collecting tank; a sample introduction pipe which is communicated with the interior of the sample collecting tank is fixed on the upper portion of the sample collecting tank; a high pressure pipe is fixed on the sample introduction pipe; a hollow pipe is fixedly arranged on the sample collecting tank; the lower portion of the hollow pipe is located in the sample collecting tank. According to the underbalanced well drilling and logging detection sampling device, the structure is reasonable and compact and the usage is convenient; the whole gases to be detected in mud can be collected due to the high pressure pipe and the sample collecting tank, so that the integral hydrocarbon value of the gases to be detected can be obtained, accordingly the condition that downhole oil and gases return upward can be truly reflected, and accordingly the amount of the oil and gases can be judged according to the integral hydrocarbon value; the downhole condition can be predicted at first time and ignition blowout-prevention shut-in operation can be timely performed when ignition blowout-prevention shut-in is required and accordingly the threat to the personal safety of staff is reduced and the loss of property is reduced.
Description
Technical field
the present invention relates under balance pressure drilling well logging sampler technical field, is that a kind of under balance pressure drilling well logging detects sampler.
Background technology
in inflation liquid phase under balance pressure drilling process, in order to know the real conditions of down-hole oil gas, the mud of extracting out from shaft bottom is obtained to the analysis that gas to be measured carries out the total hydrocarbon value after separating, and the total hydrocarbon value by gas to be measured, can reflect the situation of returning on the oil gas of shaft bottom.Existing gas to be measured is the gas to be measured that mud is obtained through liquid-gas separator in advance, the gas to be measured obtained after liquid gas separating treatment is owing to existing that separating effect is not good maybe goes to the subsequent detection analysis procedure by the gas to be measured obtained after separating, the phenomenon of leakage can occur in part gas to be measured, therefore the component of gas to be measured that enters follow-up hydrocarbon value detection-phase is imperfect, can not obtain thus complete total hydrocarbon value, thereby can not reflect truly from this total hydrocarbon value the situation that shaft bottom oil gas returns, in addition, when needs igniting blowout prevention closing well, can't the very first time predict downhole conditions, the blowout prevention closing well that causes lighting a fire is carried out and is delayed, thereby the personal safety to personnel threatens, and cause the loss of property.
Summary of the invention
the invention provides a kind of under balance pressure drilling well logging and detect sampler, overcome the deficiency of above-mentioned prior art, it can effectively solve the problem that existing sampler fails to collect whole gas to be measured.
technical scheme of the present invention realizes by following measures: a kind of under balance pressure drilling well logging detects sampler, comprise the sample collection tank, be fixed with the sample feeding pipe communicated with sample collection tank inside on the top of sample collection tank, be fixed with high-voltage tube on sample feeding pipe, be installed with hollow section on the sample collection tank, the bottom of hollow section is positioned at the sample collection tank, at the lower outside of hollow section, the air inlet communicated with hollow section inside is arranged, and in the bottom of hollow section, is fixed with agitator.
below the further optimization and/or improvements to the foregoing invention technical scheme:
can there be mud discharging mouth lower end in above-mentioned sample collection tank, is installed with the flashboard that can block mud discharging mouth on the sample collection tank, and the locating hole that is no less than two is arranged on flashboard, is installed with alignment pin in locating hole.
above-mentioned hollow section can be the hollow metal screwed pipe, and the hollow metal screwed pipe is fixedly mounted on the sample collection tank by nut, in the outside of sample collection tank, is installed with elevated trough.
can be installed with high-voltage tube by union on above-mentioned sample feeding pipe, be installed with choke valve on high-voltage tube.
but above-mentioned choke valve can be adjusting joint stream valve or sleeve type choke valve.
reasonable and compact in structure of the present invention, easy to use, the setting of high-voltage tube and sample collection tank, can collect the gas whole to be measured in mud, thereby can obtain the total hydrocarbon value that gas to be measured is complete, and then can reflect truly the situation of returning on the oil gas of shaft bottom, and then can be according to complete total hydrocarbon value judgement oil and gas content; When needs igniting blowout prevention closing well, can the very first time predict downhole conditions, carry out in time the operation of igniting blowout prevention closing well, reduce the threat to personnel's personal safety, and reduced the loss of property.
The accompanying drawing explanation
accompanying drawing 1 is the main TV structure schematic diagram of most preferred embodiment of the present invention.
coding in accompanying drawing is respectively: 1 is the sample collection tank, and 2 is sample feeding pipe, and 3 is high-voltage tube, and 4 is the hollow metal screwed pipe, and 5 is agitator, and 6 is alignment pin, and 7 is flashboard, and 8 is nut, and 9 is elevated trough, and 10 is mud discharging mouth, and 11 is air inlet.
The specific embodiment
the present invention is not subject to the restriction of following embodiment, can determine concrete embodiment according to technical scheme of the present invention and actual conditions.
in the present invention, for convenience of description, the description of the relative position relation of each parts is all to be described according to the Butut mode of Figure of description 1, as: the position relationship of forward and backward, upper and lower, left and right etc. is to determine according to the Butut direction of Figure of description 1.
below in conjunction with embodiment and accompanying drawing, the invention will be further described:
as shown in Figure 1, this under balance pressure drilling well logging detects sampler and comprises sample collection tank 1, be fixed with the sample feeding pipe 2 communicated with sample collection tank 1 inside on the top of sample collection tank 1, be fixed with high-voltage tube 3 on sample feeding pipe 2, be installed with hollow section on sample collection tank 1, the bottom of hollow section is positioned at sample collection tank 1, at the lower outside of hollow section, the air inlet 11 communicated with hollow section inside is arranged, and in the bottom of hollow section, is fixed with agitator 5.During use, well logging total hydrocarbon detection probe tube and hollow section are fixedly installed togather, mud enters in sample collection tank 1 by high-voltage tube 3, mud is under the stirring of agitator 5, gas to be measured in mud is overflowed from mud, then gas to be measured all enters in hollow section by the air inlet 11 on hollow section, last gas to be measured detects probe tube by the well logging total hydrocarbon and enters the follow-up detection analysis phase, by the detection analysis to gas to be measured, can obtain the total hydrocarbon value that gas to be measured is complete, complete total hydrocarbon value reflects the situation of returning on the oil gas of shaft bottom truly, and then total hydrocarbon value that can be complete according to gas to be measured judgement oil and gas content, when needs igniting blowout prevention closing well, can the very first time predict downhole conditions, carry out in time the operation of igniting blowout prevention closing well, reduce the threat to personnel's personal safety, and reduced the loss of property.
can according to actual needs, above-mentioned under balance pressure drilling well logging be detected to sampler and make further optimization and/or improvements:
