泥浆洗井技术,对于钻进复杂地层十分重要.除了应选用合理的配方外,还存在着如何针对所钻地层,调配好泥浆性能以及现场对泥浆的科学管理问题. 我队在口前矿区施工中,所钻地层岩石破碎.几乎各孔都有坍塌掉块与漏失问题.开始虽采用了泥浆洗井,但由于对泥浆性能的合理选择与调配不够重视,所以经常发生坍塌和埋钻事故,致使生产效率降低,井故率上升,给施工带来很大困难.对此,我们采用了与该区岩层情况相适应的泥浆配方,配制了性能与之相适应的浆液,在
Mud flushing technology is very important for drilling into complicated formations.In addition to choosing a reasonable formula, there are still some questions about how to adjust the mud performance and the scientific management of the mud on the site, , The strata of the rock to be drilled are fractured, and almost all the holes have collapsed blocks and leakage problems.While the mud flushing was started at the beginning, the collapse and burying accidents often occur due to insufficient attention paid to the reasonable selection and deployment of mud performance, Resulting in lower production efficiency and higher production rate, which brings great difficulties to the construction. In this regard, we have adopted a slurry formulation that is compatible with the rock formation in the area and formulated a slurry with suitable performance
