摘　　要：针对东辛油田部分套窜井出砂导致油井停产,影响单井开发效果的矛盾,应用套窜出砂井治理技术进行治理.2008年10月6日至2011年3月31日应用该技术共治理东辛油田不同区块的套窜出砂井4口,施工成功率100%,有效率100%.截止目前,正常生产下的4口井,恢复日产能24.3m3,平均日增油6.4m3,累计产油8 598.3m3,增油2 871.8m3,有效期最长的已超过937d且继续有效.该技术的成功应用为东辛油田同类井的治理提供了借鉴经验,并且具有货源广、成本低、适用范围广、有效期较长的特点.Owing to production halts resulting from some sand-drained well with casing channeling,a corresponding technology is presented.From October 6,2008 to March 31,2011,4 sand-drained wells with casing channeling are governed via this technology,both the success rate and the effective rate are 100%.So far,the daily capacity is 24.3m3,daily oil-increased is 6.4 m3,the accumulative total oil is 8598.3 m3 and the total oil-increased is 2871.8 m3.The longest effective period have exceeded 937 days and even continued to be effective.The technology is characteristic of rich supply of goods,low cost,broad scope of application and long period of validity.It is worth using for references for similar wells.
