温米油田共有抽油井337口,开井237口,占温米采油厂采油井总数的80%,单井平均产液量11.6m~3/d,单井平均产油量4.6m~3/d,平均含水55.3%,泵效29.39%。平均动液面1532m,平均泵挂2140.93m。1抽油井井口装置存在的问题吐哈盆地冬季温度通常低于-10℃,有时甚至达到-30℃。低温情况下,在停井或套压低于油压时,套管定压放气阀容易冻堵,造成放气阀球座无法打开(油井气锁)或无法关严(倒灌),
There are 337 pumping wells in Weimi Oilfield, with 237 wells open, accounting for 80% of the total production wells in Wenmi Oil Production Plant. The average single liquid production volume is 11.6m 3 / d and the average single oil production 4.6m 3 / d, the average water content 55.3%, pump efficiency 29.39%. The average moving surface 1532m, the average pump hanging 2140.93m. 1 pumping wellhead device problems Turpan-Hami Basin winter temperature is usually below -10 ℃, and sometimes even reached -30 ℃. Under low temperature conditions, when the well is shut down or the casing pressure is lower than the oil pressure, the casing fixed pressure release air valve is easy to freeze and block, resulting in that the air release valve seat can not be opened (oil well air lock)
