射孔的关键是把射孔枪准确的送到目的层段,将顶部第一发弹对准目的层顶界。习惯上把这项对射孔层点火深度进行准确定位的工作称为射孔校深。在玉门油田现阶段应用最多的是用相对深度法进行射孔深度定位,文章对影响射孔深度定位精度的主要因素进行了分析,并提出了解决该问题的相应办法。 The key to perforation is to send the perforating gun accurately to the target interval and aim the top one at the top of the target. Habitually put the perforating layer firing depth for accurate positioning of the work known as perforation school. The most widely used method in Yumen Oilfield at this stage is to use the relative depth method to locate the perforation depth. The paper analyzes the main factors that affect the perforation depth positioning accuracy and puts forward corresponding solutions to this problem.
