射孔完井是目前国内外使用最广泛的完井方法。射孔是将射孔器下至油气井目的层位。射穿套管、水泥环并射入地层一定深度,建立地层流体与井筒的流动通道。采用合适的射孔器和射孔工艺,就可以使射孔对产层的伤害最小,完善系数高,从而获得理想的产能。
Perforating completion is the most widely used completion method at home and abroad. Perforation is the perforator down to the purpose of oil and gas well. Shoot through the casing, cement ring and into the formation of a certain depth, the formation of fluids and wellbore flow channel. Using the appropriate perforator and perforation process, you can make the perforation on the formation of the smallest damage, improve the coefficient of high, so as to obtain the desired capacity.
