随着几十年的发展,射孔技术有着突飞猛进的进步。射孔的目的是沟通套管内腔和地层,保证油井获得应有的产能。影响射孔完井产能的因素有很多,主要有射孔参数(孔深、孔密、孔径、相位角、射孔格式)、地层(油层)损害等。分析研究这些因素以及和产能间的关系,就可以针对不同的井,采用不同的方案,提高油气井产能。
With decades of development, perforation technology has made rapid progress. The purpose of perforation is to communicate the casing cavity and formation to ensure that the well receives the proper capacity. There are many factors affecting perforation completion productivity, mainly including perforation parameters (hole depth, hole density, hole diameter, phase angle, perforation format), formation (oil layer) damage and the like. Analysis of these factors and the relationship between capacity and production can be for different wells, using different programs to improve production capacity of oil and gas wells.
