Abstract: | In oil long--term development process , under the condltxon ot high pressure wateriloooing , casing damage has caused a growing influence . When high pressure waterflooding entering mudstone layer will form water extraction, because of the crack water filling and rock strata of the mud,its physical properties can produce major changes, mudstone layer will produce displacement under the effect of pressure difference. The size of the injection pressure directly influences the casing life. Therefore, Deterrninating reasonable surface pressure of injection wells is one of the effective means for extending service life of the casing, pressure boundary of Injection Wells should be based on rock burst pressure on oil reservoir. The burst pressure as pressure boundary of oil reservoir and casing protection is used to design the reasonable injection pressure. |
