现有注水泥器完成注水泥作业后,需要投塞憋压关闭注水泥循环通道,但易发生注水泥循环通道关闭不严,水泥浆倒灌从而影响固井质量。为了克服上述问题,本文研发了多功能注水泥器,能够有效解决碰压后难以关闭循环孔的问题。该产品的胶塞座采用了新型材料,易钻、不易留环,能够有效降低后期作业风险。该产品结构简单合理,易于操作,减少作业程序,提高工作效率,注水泥通道开启、关闭安全可靠。已经在大港、冀东等油田现场应用138口井,平均缩短完井时间6~12小时,经济和社会效益显著。
After the existing cementing machine is finished with cementing operation, the cementing cementing tunnel needs to be closed by the pressure of the cementing plug, but the cementing circulation channel is prone to be closed and the cementing slurry is impacted to affect the cementing quality. In order to overcome the above problems, this paper developed a multi-functional cementing machine, which can effectively solve the problem of difficult to close the circulation hole after the pressing. The product’s rubber plug seat uses a new type of material, easy to drill, not easy to stay ring, can effectively reduce the risk of late work. The product structure is simple and reasonable, easy to operate, reduce operating procedures, improve work efficiency, cement channel open, closed and safe. 138 wells have been used on-site in Dagang and Jidong Oilfield, shortening the completion time by 6 ~ 12 hours on average, with significant economic and social benefits.
