低密度高炉矿渣水泥浆固井技术这样一个概念主要是针对于我们国家目前在多处油田中都已经遇到的一个实际问题而提出的,即在油田的低压区宜漏底层处所产生的固井水泥浆返高以及由此所导致的固井质量问题。在本文中,我们具体选择了三种低密度矿渣水泥浆来进行相关的试验探究,对其相关各方面的性质进行研究,如流变性、稳定性、抗压抗拉强度和凝结时间等,最后得出以下结论:三种低密度矿渣水泥浆在试验中均表现出良好的性质,即流变性好、稳定度高等。并根据实际的工程实践知其在施工中的应用操作简便且固井质量较高,这一系列的结果都表明低密度高炉矿渣水泥浆在固井技术中的巨大优势,必将引起固井相关人士的高度关注和重视。
The concept of low-density blast furnace slag cementing technology is mainly aimed at a practical problem that our country has encountered in many oil fields at present. That is, the well cementing produced in the low pressure area of the oil field should drain The return of cement slurry and the resulting cementing quality problems. In this paper, we have selected three kinds of low-density slag slurry to carry out the relevant test to explore the nature of its various aspects of research, such as rheological properties, stability, compressive strength and setting time, the final The following conclusions are drawn: The three low density slag slurries show good properties in the test, ie, good rheological properties and high stability. According to the practical engineering practice, its application in construction is easy to operate and the cementing quality is high. These series of results show that the great advantage of low density blast furnace slag cement in cementing technology will surely cause cementing related People pay great attention and attention.
