长庆油田X区块套损井腐蚀规律研究及措施改造
Corrosion Law of Damaged Wells in Block X of Changqing Oilfield and Measures for Improvement
摘要
Abstract
The block X of Changqing Oilfield has the characteristics of low porosity,low permeability,low pres-sure,and low production.The formation water has high mineralization and is rich in corrosive ions.With the exten-sion of oil well production time,the number of oil and water well casing damage caused by corrosion has increased year by year,seriously affecting the injection production balance in block X and severely restricting the long-term stable production.In order to further know the corrosion law of damaged wells in block X,a statistical analysis of damage wells date is conducted and the cause of casing damage from geological layers,production factors,wellbore factors and corrosion factors is analysized in detail in the research area.Based on the corrosion characteristics and development status,a reasonable Improvement plan has been developed for potential wells that can restore pro-duction.关键词
