水平裸眼井砾石充填防砂控水技术应用

Application of gravel pack sand control and water control technology in horizontal open-hole well

伴随水平裸眼井的开发生产,出砂和水锥问题严重影响油井的产能和寿命。裸眼井砾石充填结合油藏控水技术,利用遇油遇水膨胀封隔器分段,配合自适应控水流量阀(AICD),有效实现延缓底水锥进、提高油藏采收率。

With the development and production of horizontal open hole Wells,the problems of sand production and water coning seriously affect the productivity and service life of oil Wells.Open-hole gravel pack combined with reservoir water control technology can effectively delay bottom water coning and improve reservoir recovery by using oil-water expansion packer and adaptive water flow control valve(AICD).
