南黄海大陆架科钻CSDP-02井第四系、新近系地层海水冲洗液研究与应用

Study on Seawater Flushing Fluid and Its Application in Quaternary and Neogene Strata for CSDP-02

摘要:

针对南黄海大陆架科学钻探第四系、新近系地层，通过室内实验，以多功能剂（MBM）和抗盐共聚物（GTQ）为主要处理剂，选出适合第四系、新近系地层的冲洗液配方，并在CSDP-02井海上施工现场应用，取得了良好的效果，保证了钻探施工在第四系、新近系地层中的顺利进行。

Abstract:

The south Yellow Sea continental scientific drilling project is carried out in Quaternary and Neogene strata, according to the strata characteristics, multifunctional agent (MBM) and anti-salt copolymer (GTQ) were chosen as the main agents for indoor experiments to prepare flushing fluids. The suitable formula of flushing fluids was selected for Quaternary and Neogene strata drilling and applied in the offshore drilling site of CSDP-02, it is proved that the MBM seawater flushing fluids have good effects, which ensures the smooth drilling construction in Quaternary and Neogene strata.
