摘要
随着四川油气田水平井和大斜度井的增加,常规的固井评价测井仪器(CBL+VDL)由于受偏心等因素影响,不能精确地评价水平井和大斜度井的固井质量。通过对比分析,分区水泥胶结测井仪(SBT)不受偏心影响,能够满足这两种井的固井评价,并且可以精细地评价各个分区的水泥胶结情况,为油公司采取下一步措施提供详细的固井情况分析。
The well cementation quality presently directly affects the well going into operation.Along with horizontal well and great ascent well increasing in Sichuan oil-gas field,conventional well cementation logging instrument can not precisely appraisal the cementation quality of these two kinds of wells as a result of bias influence and so on.Through contrast analysis,sector bond tool is not influenced by bias,the tool can satisfy well cementation appraisal of these two kinds of wells,and can fine appraisal each district cement bond situation.
