摘　　要：陕甘宁盆地中部气田储层渗透率很低，生产过程中地层压力传播速度的快慢，井间干扰大小，以及井间连通性等问题，是气田开发中极为关注的问题。针对这种情况，研究了陕甘宁盆地中部气田陕参1井组干扰试井测试。结果表明，地层渗透率越高，压力传播越快，压力响应越大，随着孔隙度增加，压力传播速度减少。通过观测井压力降与井距关系，确定该气田开发方案布井井距在2500—3000m范围内较为合理。这类问题的解决具有实际意义，能够直接指导气田生产。Permeability in the middle part of Shan Ganning basin is so low. The concerning problems at the producing process are fast or slow speed of transferring rate of formation pressure, big or small of inter-well influences and communication between wells. To solve these problems, interference well-test of Shancan1 well units in Shan Ganning basin is studied which results show that the formation permeability is more higher, pressure spread is more quick; and the pressure spread decreased when the pore increase. By surveying relationship between drop off pressure of observed well and well distance, the reasonable space for distributing well is from 2500 to 3000 meters. It has practical means to guide the production of gas field.
