【摘要】：油井采出液含水率的测量是油田开发中一项十分重要的工作,针对目前油井采出液人工取样存在的含水率波动大、取样代表性差、取样人员劳动强度大、效率低等问题,研制了油井采出液自动取样器。该取样器通过加大单剖面斜度或多孔道式取样头,增大了取样剖面,提高了取样代表性,防残液回流装置保证了油井采出液取样的真实性。现场试验表明,该取样器取样稳定性好,含水波动基本在2%左右,比人工取样更具代表性,更能反映油井真实含水。
[Abstract]:The measurement of water cut of oil well produced liquid is a very important work in oilfield development. In view of the problems of large fluctuation of water cut rate, poor representativeness of sampling, large labor intensity and low efficiency, etc, artificial sampling of oil well produced liquid exists at present. An automatic sampler for producing fluid from oil wells has been developed. The sampler increases the sampling profile and the sampling representativeness by increasing the slope of a single profile or a multi-pass sampling head. Field test shows that the sampling stability is good and the fluctuation of water cut is about 2%, which is more representative than manual sampling and can reflect the true water cut of oil well.
