In view of cementing mechanism of dual contacts in cementing and the practical problems in field operation, this paper makes a basic analysis of isolation system of dual contacts, describes its downhole behavior and determines iour crucial factors affecting upon dual contacts. The test was studied for the properties of dual contacts and the preliminary test results was introduced. A new understanding for the effect of filtrate cake upon dual contacts is presented as well as the cementing and sealing to barriers and the cementing quality of high and low pressure formation.

从固井二界面的胶结机理出发.联系现场实际问题,通过对二界面封固系统的基本分析,阐述了二界面封固系统的井下状态.确定了影响二界面的四大类基本因素。开展了二界面。性质的试验研究,给出了初步的试验结果,对滤饼在二界面的作用提出了新的认识,对隔层的胶结和密封以及高压层和低压层的固井质量问题也提出了相应的认识。

Through researching the effect of filtrate for cement slurry by the molecular weight,hydrolysis degree and the addition of partially hydrolyzed polyacrylamide (HPAM),the results indicate that HPAM with molecular weight of 600~650 thousand, hydrolysis degree of 6.0%~7.0%, and addition of 0.5%~0.7% could greatly reduce the amount of filtrate for cement slurry. The experiment conditions have been obtained for synthesizing this molecular weight and the degree of hydrolysis of HPAM. The base on HPAM...
