寿光地区卤水资源丰富,钻探施工中由于泥浆遭遇盐侵,导致钻探事故,甚至钻孔报废等情况。经过多次实验,总结出该区的泥浆配制方法:首先配制淡水泥浆,然后在泥浆中加入一定浓度的盐溶液和抗盐、提粘效果好的泥浆处理剂,从而配制成盐水泥浆。应用表明,该泥浆具有所用处理剂少,配制简单,易维护,抗盐能力强,抑制效果好,携带岩粉能力强,能有效地解决施工遇到的问题,保证了钻孔的顺利完工。
Brine resources are abundant in Shouguang area. Due to the salt intrusion in the drilling construction, drilling accidents and even drilling scrapped are caused. After many experiments, it is concluded that the mud preparation method in this area is as follows: Firstly, freshwater slurry is prepared, and then a certain concentration of salt solution and anti-salt and viscous effect mud treatment agent are added to the slurry to prepare brine slurry. The application shows that the mud has the advantages of less treatment agent, simple preparation, easy maintenance, strong salt resistance ability, good suppression effect, strong carrying rock powder, effectively solving the problems encountered in the construction and ensuring the smooth completion of the drilling.
