摘　　要：苏码头气田生产过程中存在气井压力下降快、稳产时间短、气井之间关井压力和产能差异大,特别是经加砂压裂后,井内情况复杂,采用以往的试井工艺难以达到测试要求等情况,严重影响了开发结果。为加深对气田储层特性的认识,研究蓬莱镇组气藏的稳产能力,选定码浅14-4井、码浅14-2井作为干扰试井技术研究对象,利用现代电子压力计技术与传统的试井技术相结合,在极短时间内确定气田的压力系统,快速实现井间连通情况的判别,满足气田开发研究的需要,对油气田高产稳产具有积极作用。During production in Sumatou gas field occurred many phenomena including the pressure decreased rapidly, the period of stabilized production was short, the shut-in pressures and productivities of different wells were very different, and especially the hole conditions of wells became more complicated etc., so that the requirement of well test was very difficult to meet with the conventional well test technique and that the development result was badly affected. In order to get a deeper understanding of the characteristics of the gas reservoir and the stabilized productivity of Penglaizhen gas reservoir, Wells Maqian14-4 and Maqian14-2 were chosen to do an interference test between wells with combination of modern electronic pressure gauges and conventional test technology, and very good results were obtained in a very short time: the pressure system of the gas reservoir and connectivity between the tested wells have been identified, and so requirements of development of the gas field were met, which paid an important roll in achieving high and stabilized production in the gas field.
