摘要
在试油排液求产施工中,出现封隔器失封或者泄压,严重影响试油资料的录取,甚至直接导致返工。针对地层超压、入井过程封隔器胶筒损坏、坐封力不足以及工具自身缺陷这些因素,在现场施工中采取相应措施,解决封隔器失封泄压问题,满足施工需要,确保试油优质资料录取。
During operation process of oil test and drain production,the emergence of missing seal or packer pressure relief seriously affects requirement of oil testing data,or results in rework.For the factors of overpressure of formation,damage of packer elementwhen it lowering into the wellbore,not enough of set weight and defects of the testing tool itself,taking appropriate measures during field operation,the problem of sealing loss of packer has been solved to meet the needs of operation,which ensure the measurement of test oil data.
