CAUSES AND MEASURES OF CASING PIPE

Oil casing damage because of the complexity, many scholars at home and abroad were research in many aspects, although opinions vary, but also has certain similarities, which is developing casing damage preventive measures to provide the necessary conditions.
1 cause analysis of casing damage
Oil and water wells casing damage caused by factors are the general factors of Geology and geological factors and engineering factors: stratigraphy (reservoir) is heterogeneity, formation dip, rock properties, formation of fault activity, underground seismic activity, crustal movement, formation corrosion situation is the result of difference of the objective conditions for the existence of the oil well casing technology in. These internal factors, once aroused, the generated should force change is great, will make oil and casing damage, and even lead to casing damage, serious interference development plan implementation, the threat of oil field.
Engineering factors causing casing damage of main engineering factors: during drilling and completion the completion quality, casing material, cementing quality, oil field water injection, fracturing, acidizing, and oil wells daily management work and so on.
