Taking the Φ88.9 mm oil pipe gas seal test as an example,combined with the existing airtight seal testing tool,analyzing the force situation under the two conditions of the tool sitting seal and working condition,the theoretical dimension design of the gas seal testing tool is carried out on the basis of the force analysis of the tool.The ABAQUS software is used to establish the simulation model of the rubber cylinder,and three kinds of terials are optimized and simulated.The Mises stress and contact stress distribution of the rubber materials,the height of the five groups of rubber tubes and the inside diameter of the six groups of rubber cylinders are obtained,and the material,size and inner diameter of the rubber cylinder are selected and finally,four sets of built-in compression type gas seal de-tection tools with different sizes were successfully developed.The test application of 8 wells shows that the built-in compression gas seal testing tool has the characteristics of stable per-formance,reliable seal,high detection pressure grade and simple operation.It has a broad application prospect in the field of oil and gas well casing thread connection gas seal detection.
