榆某井区三维地质建模及数值模拟研究

Three-dimensional geological modeling and numerical simulation study in Yu well

该井区为榆林气田低渗、低产区,储层物性差,单井产量低,压力下降较快,大部分井采取低配长稳或间歇开采方式。因此,在该井区开展三维地质建模和数值模拟研究,对气藏进行三维描述,加深地质认识,确定适合低产区的开发指标,对指导气田合理开发和下一步开发调整具有十分重要的意义。

Yu X wellblock is a low-permeability field.Because of its poor reservoir properties,low and low production wellblock of yulin gas single well production and rapid dropping pressure,most wells were exploited with a steady or intermitent way.Therefore,threedimensional geological modeling and numerical simulation study of this area are important to three-dimensional description of gas reservoir,to enhancing the geological understanding, to identifying suitable development indicators of low production area,to guiding the development of gas fields and to adjusting the development plan.
