截至2014年6月9日,由中国石油宝鸡石油钢管有限责任公司(简称宝鸡钢管)自主研制的高性能55钢级SEW膨胀套管,在中国石化西北局塔河油田TH12124CH井安全可靠地运行了56d。现场数据表明,国产SEW膨胀套管各项性能指标均满足膨胀施工工艺和后续二开水平钻井作业要求,达到国内领先水平,可与国外同类产品相媲美。据了解,这批膨胀套管是4月14日成功下井的,这也是国产同类产品首次下井作业,下入长度526.88m、井深6 065m、最大井斜65.8°,创国内下入长度最长、井深最深和井斜最大三项纪录。膨胀套管是一种特殊的石油专用管,一般通过液压或机械方式使管柱径向膨胀10%~30%,用于套管补贴、特殊地层处理、尾
As of June 9, 2014, a high-performance 55-grade SEW expansion sleeve independently developed by PetroChina Baoji Petroleum Pipe Co., Ltd. (Baoji Steel Tube) has operated safely and reliably in TH12124CH Well of Tahe Oilfield, Northwest Bureau of Sinopec Corp. 56d. The field data show that all the performance indexes of domestic SEW expansion casing meet the requirements of expansion construction technology and subsequent two horizontal drilling operations, reaching the leading level in the country and comparable with that of similar foreign products. It is understood that these expansion casing was successfully went down on April 14, which is the first time domestic products go down well operations, into the length of 526.88m, the depth of 6 065m, the maximum inclination of 65.8 °, a record length into the country under the longest, The deepest well and the largest deviation of the three records. Expansion casing is a special oil-specific pipe, usually by hydraulic or mechanical means to make the radial expansion of 10% to 30%, for casing subsidies, special formation treatment, tail
