Research on Oil and Water Well Casing Damage in the Process of Oil-Field Development

Abstract:

The well casing damage is common during the oilfield exploitation .Analysis on casing damage in a wide range , especially in the late term of exploitation ,indicates that the major influence factors which lead to wide-range casing damage are water injection pressure , block pressure differential and water soaked area .We conclude several types of abnormal strata pressure distribution which are common existing after water injection .These analysis are good preparation for monitoring and take precaution against casing damage .It has significant benefits for prolonging oil and water well casings serviceable life , as well as sustainable and stable production.
