油井稳定试井解释在吉林油田的应用

在稳定试井解释时,通过数据预处理技术,可判断和筛选各个测试点的合理性,做指示曲线、确定指数式产能方程,计算该井潜产量和油藏各项参数。A井稳定试井不足之处在于压力计未下到油层中部,只是随泵深增加而增加,在统计流动压力时还需要折算,给试井解释带来困难。通过多次调取井的工作制度、泵挂深度取得资料,对抽油机生产井稳定试井是一种尝试。

Application of Steady Well Testing for Oil Wells in Jilin Oilfield

Rationality of each test point of steady well testing can be judged by using data preprocessing technique.Then the index curves and index production equations are obtained.The potential production of well and parameters of the reservoir are calculated.The shortcoming of steady well testing in well A is that the pressure gauge is not down to the middle point of the reservoir.As the depth of the plunger increasing,the depth of pressure gauge increases.Flow pressure should be converted,which cause well test interpretation is difficult.Update data of working system and depth of the plunger are necessary for steady well testing of rod pumped well.
