摘要
对阻抗式产出剖面测井仪器,在三元复合驱开发阶段的含水率测量效果进行了研究。首先通过现场油井井口取样初步判断油井乳化情况。然后对井口取样开展室内乳化观察实验和含水率测量实验,对仪器测量含水率的可行性和准确性进行评价。最后利用测井仪器进行了产出剖面现场试验验证。室内实验和初步现场试验表明,在含水率大于80%、油井发生乳化时,阻抗式产出剖面测井仪器能够准确测量油井的含水率。
The effect of water--cut measurement of impedance type production profile logging instrument was studied in the development phase of ASP flooding. First, preliminary judged whether the oil wells emulsified through wellhead sampling. Then interior emulsion observation experiment and water- cut measurement experiment of the wellhead sampling were conducted, the feasibility and accuracy of measuring water-cut of the instrument were evaluated. Finally, field tests were conducted by the production profile logging instrument. Interior experiments and preliminary field tests show that the impedance type production profile logging instrument can accurately measure the water--cut when oil wells＇water-cut greater than 80% and emulsified.
