摘要
为解决新井常规试油投产工艺作业工序多、周期长、压井作业对油气层伤害大等问题,研究出一种射孔与电潜泵联作工艺技术。该技术利用"Y"接头将射孔管柱与电潜泵生产管柱有机组合在一起,优化管柱连接、射孔减震装置、起爆方式等配套技术,降低射孔震动对电泵电缆与传感器的震动影响,实现了射孔与投产一趟管柱下入,并在244. 5mm套管的大位移深井内成功应用。该技术与常规试油技术相比,简化了作业工序,节省了作业成本,保护油气层免遭二次伤害,降低井控安全风险。通过适用范围的拓展研究,该技术可成为试油完井技术的一个发展方向。
New wells often encounter some problems during thetesting,such as complex operation procedures,long operating cycles,and reservoir damage.In order to solve these problems,this paper developed a testing technology with combination of perforation and ESP.The technology uses the“Y”joint to combine the perforating string with the ESP production string,so as to optimize the supporting technology such as the connection of string,the perforation damping device and the detonation method.These advantages can reduce the perforating vibration impact to the cable and the sensor of the electric pump and realize that the perforation and the production with one-trip string.This technology has been successfully applied in large displacement deep wells with a casing diameter of 244.5 mm.Compared with conventional testing technology,this technology simplifies the operation process,saves the operating costs,reduces the secondary damage to the reservoir,and reduces the safety risk of well control.
