新疆准噶尔盆地西北缘勘探区块属低孔低渗储层,具有国内外低孔低渗储层的共性,同时分布广、岩性复杂多变,具有自身的特性,通过勘探区块150多层的试井解释,并对试井双对数曲线类型及特征进行统计分析研究,结合相应的压力恢复速率曲线和措施效果,对比分析研究其共性,获得了该勘探区块4种试井曲线类型和相应的措施改造建议。现场实际应用表明,此研究结果为该勘探区块试油层措施改造决策提供了科学的指导,提高了试油经济效益。
The exploration block in the northwestern margin of Junggar Basin in Xinjiang is a low-porosity and low-permeability reservoir that has the commonality of low-porosity and low-permeability reservoirs at home and abroad. At the same time, it has a wide distribution and complex lithology. It has its own characteristics. The well logging interpretation and the double logarithmic curve type and characteristics of the well test were statistically analyzed and studied. Combined with the corresponding pressure recovery rate curve and the effect of the measure, the commonality of the well logging curves was obtained and the four types of well testing curves And the corresponding measures to transform the proposal. The practical application in the field shows that the results of this study provide scientific guidance for decision making of oil recovery measures in the exploration block and improve the economic benefits of oil testing.
