| 摘 要： | 在稀油开采过程中,油井结蜡是影响油井正常生产的一个重要原因。通过室内及现场试验表明,降凝防蜡冷输剂能够明显降低原油凝点,具有优良的改善原油低温流动性的特性,能够起到很好的油井防蜡效果,达到油井井筒防蜡及管道降凝低温输送的要求。在茨78块通过井口套管连续定量点滴加药,利用防蜡降凝冷输剂优良的蜡晶分散和改善原油低温流动性的功能,实现整个区块油井的井筒防蜡,井口至计量站、计量站至转油站、转油站至联合站输油管道全线降凝低温输送,从而实现井筒防蜡管道降凝低温输送一体化。

| Abstract: | During the recovery of light oil,paraffin deposition in oil wells is a major factor affecting the normal production of oil wells. It can be seen from tests that antifreezing and paraffin-control and cool transportation agents can be very effective in paraffin control for reducing the freezing point of the oil and meeting the requirements of low temperature transportation in pipelines. After in-lab and field tests, the low temperature flowability of crude oil is improved through antifreezing and paraffin-control and adding cool transportation agents,and the low temperature transportation of waxy light oil is realized. By utilizing antifreezing and paraffin-control and cool transportation agents to disperse wax crystals and improve low temperature flowability of the crude oil,wellbore paraffin control as well as low temperature transportation of crude oil from wellhead to metering station, from metering station to transferring station and from transferring station to central processing unit in the entire block of Ci78 is made possible, thus wellbore paraffin control and antifreezing and low temperature transportation in pipelines are realized integrately. |
