一种新型大压差测试封隔器的应用
|
摘要
基于常用的RTTS封隔器不能满足塔里木油田勘探开发需要,江汉工程井下测试公司引进了哈里伯顿CHAMP XHP封隔器。该封隔器是一款套管悬挂可封隔双向压力的机械可回收式封隔器,自带旁通,便于解封,自带水力锚机构可有效防止封隔器向上移动,具有使用方便,性能可靠、封隔效果好等特点。以TZZX井为例,优化CHAMP XHP封隔器现场施工工艺,计算其在井下的下井深度,经室内密封性试验检测后应用于现场,效果良好,可在超深超高压高温油气井进行推广应用。
Halliburton Company's CHAMP XHP packer is introduced to Tarim Oilfield because common RTTS packer can't meet the need for its exploration and development.It is a mechanical recyclable packer which brings the bypass for deblocking easily and hydraulic anchor for preventing upward movement of the packer effectively with the characteristics of convenience in use,reliable performance and better packing result.Field operation technology of CHAMP XHP packer is optimized.Its downhole depth is worked out.The packer goes through lab encapsulation test and application in TZZX well and achieves a better application result,suitable for oil and gas wells with ultra depth,ultrahigh pressure and temperature.
