MOBILE GAS WELL SURVEY PLANTS

(PUIS)

PUIS-300-16-U1 plant is intended for operational research of underground gas storage well without gas release into atmosphere.

The first PUIS-300-16-U1 plant was developed, manufactured and supplied to Proletarskoe underground gas storage (PUGS) UMG Kharkovtransgaz, where it passed acceptance tests in June 2004 and was accepted into operation.

Climatic performance of the installation is U, the category of location is 1, according to GOST 15150-69 it is permitted to operate the plant at outdoor air temperature from 243 (minus 30º) t 313 (40º) and relative air humidity t 100% at 298 (25º), as well as with dust and atmosphere precipitations.

Apply international standards ANSI, API, ASME, DIN, ISO, GOST, DSTU.

PUIS-300-16-U1 technical characteristics

Surveyed medium hydrocarbon gas, condensate, deposit water, methanol, diethyleneglycol.
Method of well research without gas release into atmosphere
Characteristics of the surveyed wells wells with a wide range of flow rate, pressure and gas composition.
Nominal flow capacity of the plant’s separator, nm3/24 h 300 000
Maximum flow capacity of the plant’s separator, nm3/24 h 500 000
Estimated gas pressure at plant inlet, МPа 16
Operating gas pressure at plant inlet, МPа maximum 15.
Efficiency of separation of the separator, % minimum 95.
Capacity of the condensate tank, l 250
Temperature range of the surveyed and ambient media at which the plant maintains its serviceability, ºС from minus 30 to 40
Weight of plant, t maximum 8.0
Overall dimensions of the plant during transportation, mm, maximum: length/width/height 8300/2600/4000

Main advantages of the plant:

  • well survey cycle in stationary modes without gas release into atmosphere;
  • offered plant provides an opportunity of survey of wells with a wider range. It is more mobile in comparison with the similar equipment;
  • notebook with the set of uninterruptible power supply unit and program software for data processing is available. It helps to perform on line visual inspection with printing of reports;
  • original structure of quick-detachable pipelines, elbows and new type of metal seals, reliable from the point of view of flow safety, allows connecting the plant to the well very quickly;
  • original structure of quick-detachable orifice allows replacing measuring diaphragms in a very short period of time.

Example of the entries of designation at order of PUIS: Mobile gas well survey plant PUIS-300-16-U1 U U 29.5-00158787-043:2005.

The next stage in creating of mobile plants for well surveying became development and manufacturing of PUIS- 300-16-1-U1 plant.

The plant is intended for development of oil and gas condensate wells with the purpose to obtain a complex of oil and gas condensate characteristics of well standards of performance.

PUIS- 300-16-1-U1 not only saved advantages of its predecessor, such as mobility, quick installation-removal to wellhead equipment, but possesses a number of other advantages:

  • allows connecting to a well with operating pressure of up to 35 P;
  • has horizontal separator with the increased effectiveness of gas purification from liquid and mechanical mixtures due to application of 3 stages of separation;
  • tank for collection of liquid fraction of the increased volume to 1 m3;
  • separator and tank for collection of liquid fraction are equipped with heaters with the ability to connect to mobile vapor plant;
  • plant service plant is increased and is minimum 15 years.
