超稠油-水乳状液形成能量原理实验研究

Experimental study of the energy theory of ultra heavy oil-water emulsion

超稠油热采过程中,地层及井筒中均可能导致乳状液的产生,而乳状液的性质必将影响流体流动及生产过程,因此研究乳状液形成的能量原理尤为重要。室内实验研究了超稠油-水乳状液形成的能量原理,研究结果表明:能量是超稠油-水乳状液形成的决定性因素,低温下超稠油很难形成乳状液,含水率过高也很难形成乳状液。该成果可为制定合理的开采工艺、破乳方法等提供参考。

During ultra heavy oil thermal recovery process,emulsion may form in both formation and wellbore,and its property will surely affect fluid flow and production process,so that it is important to study the energy theory of forming emulsion.Laboratory experiment has studied the energy theory of forming ultra heavy oil-water emulsion.The result shows that energy is a decisive factor of forming ultra heavy oil-water emulsion.It is difficult to form ultra heavy oil emulsion at low temperature or high water cut.This can be referred to when preparing recovery process and demulsification measures.
