摘要
在进行凝析气井试井解释时,多解性是十分常见的,而其中的原因之一是进行曲线拟合的试井解释模型不唯一。为了能得到更准确、更可靠的试井解释结果,在进行现代试井分析时如何选择凝析气井试井模型呢?这是试井工作者常常头痛的问题。在对大量凝析气井进行试井解释的基础上,本文选出具有代表性的D 20凝析气井作为例子,并在参考地质的情况下,分别用5种不同的凝析气井试井解释模型进行曲线拟合。通过比较最终得出结论,在进行凝析气井试井分析时,建议最好优先选用考虑相态变化的复合试井模型进行解释,这样得出的结果更准确、更具有可靠性。
When proceed the well testing anaysis for gas-condensate, ambiguity is usually, the one of reason is the model of proceeding curve fitting is not unique. How optimize the model of well test of gas-condensate well when proceed the well testing anaysis for gas-condensate to obtaining more exact and more dependable result？ it is the headache to the worker of well testing. In the well testing anaysis to massive the well of gas- condensate In foundation, the paper selected D20 well of gas-condensatet of having representativeness to the example ,and consulted the condition of geology,which used the model of five different the well testing of gas- condensate well to proceeding curve fitting. Finally, we sum up conclusion by comparing, When proceed the well testing anaysis for gas-condensate,we proposed that the model of well testing of gas- condensate well considering the alternation of phase state and compound condition should be preferentially select to obtaining more exact and more dependable result.
