摘要
开窗侧钻水平井技术是石油勘探、开发过程中,为提高探井成功率和油气采收率,增加老井产能的重要手段。它是利用低产、停产井和套变井的部分井筒以及完好的地面设备,在原来的井筒上开窗,通过控制井眼延伸,向地下油气层进行钻进,并最终钻达新的目的层的钻井技术。该技术在新疆克拉美丽气田的成功应用,解决了储层动用程度低、单井稳产周期短、底水锥进速度快及普通增产措施效率低等难题。为下一步火山岩气藏拓宽气井增产途径和套管开窗侧钻水平井的推广应用奠定良好的基础,为气藏中后期开发提供技术支撑。
In petroleum exploration and development processes,The sidetrack horizontal well technique is the important means to improve the success rate of oil and gaw exploration wells,and to increase the recovery rate of old wells.The technology is using part of the bore hole of the low producing well,closed well,the well casing deformation and the good ground equipment to open the window in the original bore hole,through the extension of the control borehole,the drilling of oil and gas layer.and eventually to drill a new target layer.the successful application of The technology in the Xinjiang Kelameili gas field,solved the problems such as short cycle of the single well stable production,the boottom water coning speed and the low efficiency problem,which Lay a good foundation for the promotion and application of the volcanic gas reservoir to increase the gas well stmulation chammels and window sidetracking horizontal wells,and provides technical support for the late development of the gas reservoir.
