水泥浆设计是注水泥技术的基础,应遵循的一个基本原则是整个注水泥过程(包括候凝)环空压力处于一个平衡状态。固井工程技术的发展表明水泥浆设计不仅是水泥浆密度、造浆率、容积、用水量的计算,还要考虑到完井深度、井温、井眼条件和钻井复杂问题对水泥浆的影响因素,并且要解决注水泥关键工序的顶替问题。 Cement slurry design is the basis for cementing technology. One of the basic principles to be followed is that the annulus pressure in the entire cementing process (including waiting to coagulate) is in a state of equilibrium. The development of cementing engineering technology shows that the design of cement slurry is not only the calculation of cement slurry density, slurrying rate, volume and water consumption, but also takes into account the influence of well completion depth, well temperature, borehole conditions and complicated drilling issues on grout Factors, and to solve the problem of replacement cement key processes.
