摘要
射孔技术作为完井工程的重要组成部分和试油技术的主要环节,是利用高能炸药爆炸形成的射流射穿油气井管壁、水泥环和部分地层,建立油气层和井筒之间油气流通道的一种技术。随着油气勘探开发的不断深入,复杂的储层类型以及多样的油气井完井工程对射孔技术提出了更高的要求。为满足不同的需求,近些年来射孔技术也得到了快速发展。主要介绍了油气井射孔工艺技术的现状以及将来可能的发展方向。
Perforat ion technology was an impor tant part of well complet ion engineering and the main part of oil test ing technology. The metal jet was formed after the explosion of high energy explosive. It penetrated oil and gas well pipe wall, cement ring and part formation, and oil flow passage was formed between oil gas reservoir and well bore. With the development of oil and gas exploration and development, more advanced perforation technology was required to apply to complex reservoir types and various oil and gas well completion engineering. In order to meet the different needs, perforation technology had been developed rapidly in recent years. The current situation and future development trend of perforation technology in oil and gas well was introduced mainly.
