摘　　要：川东北气藏具有超深、含硫化氢、温度高、压力高的特点,气井测试难度大。对川东北超深含硫化氢气藏测试中面临的难点和问题进行了分析,认为高温高压,地质条件复杂,含硫化氢、二氧化碳等腐蚀气体是制约川东北超深含硫化氢气井测试的主要因素。针对存在的难点和问题,主要从测试管柱选择、地面流程、测试技术及应急措施等方面,论述了超深含硫化氢气井测试技术要求和对策。Gas reservoir in Northeast Sichuan has characteristics of super deep,hydrogen sulfide,high temperature and high pressure,testing for gas well is difficult.Based on analyzing the difficulty and problem facing at test for ultra deep gas reservoir containing hydrogen sulfide in the northeast Sichuan,it is thought that high temperature and high pressure,complex geological condition,containing hydrogen sulfide,carbon dioxide and other corrosive gas is the main factor to restrict the well test.In view of the existing difficulties and problems,mainly from aspects of the selected test string,surface process,testing technology and emergency measures,requirements and countermeasures for test to the super deep gas well with hydrogen sulfide are discussed.
