APPLICATION OF SAND CONTROL TECHNIQUE IN YANGERZHUANG OILFIELD

Since 1998 oil well pumps of some sand production well have often been plugged by sand and oil reservoir are covered by sand in Yangerzhuang Oilfield, but traditional sand control technique is not satisfied, such as the effect is bad, valid period is short and cost is high, so sand control technique is studied and used.This technique include long plunger sand control pump and circulating packing sand control.Pipe string structure, mechanism of this technique, technique feature and application in field are introduced.The application in field show the 3 types of sand control technique have features as follows, constructing is simple, operating period is short, cost is less.It can prevent sand production in oil well pump, also extend oil well repaired free time.It has get good effect.
