Analysis of Reasons for Wellbore Blockage in Gas Wells and Research Progress in Blockage Removal Technology
摘要
Abstract
With the development of natural gas fields,the problem of wellbore blockage has gradually become prominent,bringing many negative impacts to production,such as prolonged operation time,reduced production capacity,reduced recovery rate,and changes in reservoir stress state.Therefore,it is crucial to identify the causes of gas well blockage and choose the correct unblocking process.By an-alyzing the causes,mechanisms,and harmfulness of different types of blockages,combined with the research progress of unblocking tech-niques,targeted unblocking techniques are proposed for different types of gas well blockages.The principles,advantages,disadvantages,and applicability of the unblocking techniques are discussed,providing reference for in-depth research and on-site application of the un-blocking techniques in gas fields.关键词
