提高鄂尔多斯北部气田固井质量的综合工艺技术

COMPREHENSIVE TECHNOLOGY FOR IMPROVING THE CEMENTING QUALITY OF GAS WELLS IN THE NORTH OF ERDOS

鄂尔多斯北部大牛地气田即将进入开发阶段,然而2 0 0 3年上半年施工的大部分井都存在严重的固井质量问题,气田开发和后续工程受到不同程度影响。因此研究和优选出适合鄂北工区的水泥浆体系显得尤为重要。介绍了鄂北气井的基本情况,对优选出的适合鄂北工区气井的DZJ和GSJ两种水泥浆体系进行了描述,并提出了提高鄂北气田固井质量的方案及配套措施。

With the coming of gas well development in Da-niudi gas field located in the north of Erdos basin, the cementing quality are becoming poorer in most wells completed in the first half year of 2003, the gas field development and successor work was affected. So, it's particularly important to select one kind of cement slurry system suited for the ERDOS gas field. The paper introduced the basic circumstances about gas wells in Erdos and analysed the properties of DZJ and GSJ cement slurry suited for gas wells in the north of Erdos and put forward the cementing project and the matching measures for improving the cementing quality of gas wells in Erdos. It will provide an effective direction for the cementing there.
