在评价水泥标准程序中采用了两种水泥胶结测井仪,但是有关人员常常对这两种测井仪的有效性及其解释结果产生质疑,因此,这两种仪器未能作为替代仪器进行层间连通性测试,经营者也对继续使用这两种测井仪的价值表示怀疑。然而,这些仪器的可靠性以及它们确定套管下低质水泥的能力却都得到了肯定。 Two cement cementation tools were used in the evaluation of cement standard procedures, but the staff often questioned the validity of both tools and their interpretation, and as a result, they failed to function as an alternative instrument In inter-connectivity testing, operators are also skeptical of the value of continuing to use both tools. However, the reliability of these instruments and their ability to determine low-grade cement under casing are well established.
