高压凝析气藏流体取样技术

Technique of Fluid Sampling in High Pressure Condensate Gas Reservoirs

研究了高压凝析气藏流体取样技术,首先提出了取样井应具备的条件;然后对取样井进行调整,调整的目的在于用油(气)藏远处的原始油(气)藏流体取代井筒周围没有代表性的油(气)藏流体;针对凝析气井取样难点,提出采用分离器取样方法对油样、气样及高压气井进行取样;最后提出应对样品进行质量检查。

The technique of fluid sampling in high pressure condensate gas reservoirs was studied,the condition of sampling wells was first proposed,and then the sampling wells were adjusted,the purpose was to use the fluid in the original oil(gas)reservoirs remote area to replace the fluid in the near wellbore of non-representative oil(gas)reservoirs.In allusion to the problem of sampling in the condensate gas reservoirs,it is proposed that a separator is used to sample for oil,gas and high pressure gas wells,eventually it is proposed that the quality of samples should be checked.
