海上低渗储层低效井成因及治理对策
Study on Causes and Treatments of Low Efficiency Wells in Offshore Low Permeability Reservoir
摘要
Abstract
The low permeability reservoir in an offshore oil field is poor in physical property.It is not connected and fails in water well injection.Oil well cannot be produced.There are many factors affecting the low efficiency,and the measures are difficult to control.To effectively solve the problem of low efficiency well treatment and improve the productivity of low efficiency well,the comprehensive treatment of low efficiency well in low permeability reservoir is adopted by integrating"geology+reservoir+technology+engineering".Based on multi-factor analysis of geology,reservoir and engineering,the causes of low efficiency well in low permeability reservoir are identified.Operable,effective,and reasonable countermeasures treatment are proposed,and laboratory evaluation experiments are carried out.Optimized and efficient supporting treatment technology,and field application to effectively release oil well productivity.Based on the experiment,the compound plugging solution system and high temperature and scale inhibitor are developed,and the field application has achieved good results.The experience of low efficiency well treatment in low permeability reservoir can provide reference for similar reservoir treatment.关键词
