利用水渗流模拟实验装置进行了压差与固井质量的关系，储层物性（主要是渗透率）、储层渗流速度与固井质量的关系等实验研究。结合现场调查和统计规律得出，高压层固井环空压差大于１ＭＰａ、低压层固井环空压差小于９０ＭＰａ的情况下，用Ａ级水泥原浆能够保证固井质量。在密井网条件下，水渗流流速在钻井固井过程中应控制小于１２０ｍ／ｄ，大于１２０ｍ／ｄ地层流体的水渗流将对固井声幅质量检测造成影响。提出了地层中水渗流主要影响水泥的溶解结晶机理，对局部化学反应影响较小。地层流体渗流损害水泥环胶结质量的机理是溶解迁移机理，水渗流通过改变溶解速率和迁移速率来影响水泥环的胶结质量，其溶解速率由迁移速率所决定。
The relationship between pressure drop and cementing quality, reservoir physical properties (mainly permeability), reservoir seepage velocity and cementing quality were experimentally studied by means of water seepage simulation experiment device. According to the field investigation and statistical rule, it is concluded that the cementing ring pressure in the high pressure formation is greater than 1MPa and the pressure difference in the low pressure formation cementing annulus is less than 90MPa. Under the condition of close well, water seepage flow rate should be controlled less than 120m / d during drilling and cementing, and the seepage flow of formation fluid greater than 120m / d will affect the sounding amplitude of cementing well. It is proposed that water seepage in formation mainly affects the dissolution and crystallization mechanism of cement and has little effect on local chemical reaction. The mechanism of formation fluid seepage damage cementing cement mass is the mechanism of dissolution and migration. Water seepage affects the cementing quality of cement rings by changing the dissolution rate and migration rate, and the dissolution rate is determined by the migration rate.
