Cementing well by using slag slurry in whole length can improve the quality of well cementing and reduce the cost of it. Based on MTC cementing well technique, universal drilling fluid cementing technology and the study of low density slag slurry, three high density BFS slurries were developed. They are called as BFS cement slurry, BFS MTC cement slurry, and BFS UF cement slurry separately.

Cementing well by using slag slurry in whole length can improve the quality of well cementing and reduce the cost of it. Based on MTC cementing well technique, universal drilling fluid cementing technology and the study of low density slag slurry, three high density BFS slurries were developed. They are called as BFS cement slurry, BFS MTC cement slurry, and BFS UF cement slurry separately. In the slurry system, BFS was used as hydration gelling material, a little amount of cement and alkalic activator was added. The density of three slurries in the range of 1.75~1.93g/cm 3. The setting time, rheology and stability of them, and their compression strength after setting were measured. The results show that, the order of their compression strength from high to low is BFS UF, BFS MTC and BFS. The strength can meet the need of downhole perforating operation. The rheology, stability and thickening time of BFS MTC slurry and BFS UF slurry can be changed by adding different kind and amount of drilling fluid.

在油气井完井固井作业中,普通硅酸盐油井水泥水化凝结硬化过程中存在较高的自缩和失水,造成水泥环与地层套管之间胶结质量差,影响固井质量。为此,研究选择了一种新型晶体生长的膨胀材料,能在水泥不同水化阶段(塑性状态饱和凝固后期)保持稳定的体积膨胀,其适用性、配伍性和膨胀时间的协调性好,在高温高压(180℃、60 MPa)下仍保持较好的膨胀。考察了微膨胀水泥浆体工程性能和在不同温度、压力、时间条件下对水泥石的线膨胀率、抗压强度、胶结强度、渗透率的影响,结果表明,新型不收缩微膨胀水泥浆体系,在常压和高温高压下均能使水泥石产生体积膨胀,水泥浆工程性能良好,抗压强度、胶结强度高,同时可改善水泥石的力学性能及渗透性能,现场固井质量优良,两界面胶结良好。
