三塘湖盆地马 7井是一口稠油井 ,在对该井进行测射联作过程中 ,二开期间稠油自溢流压曲线形成了一种特殊的波形曲线 ,与常见的压降曲线有着显著的区别 ,且流压与流温曲线形成了刚好相反的曲线特征 ,通过分析研究发现 ,这种特殊的流压流温曲线的形成与地面温度变化有关。因此 ,在开发生产过程中可以采用增温降粘的方式来提高厚油产量。 The Ma 7 well in the Santanghu Basin is a heavy oil well. During the joint shooting of the well, the heavy oil self-relieving pressure curve formed a special wave curve during the second opening period, which was in line with the common pressure drop curve The difference between flow pressure and flow temperature curve is just the opposite. Through the analysis and research, it is found that the formation of this special pressure flow temperature curve is related to the change of ground temperature. Therefore, in the development and production process can be used to increase the viscosity of the way to increase thick oil production.
