[Abstract]:Abnormal high pressure gas layer, high pressure salt water layer and high temperature and high pressure formation are often encountered in cementing. In order to stabilize formation, high temperature and high density cement slurry system is often used for cementing. However, due to its different admixtures and complex underground high temperature environment, the internal structure, crystal phase composition and slurry stability of the high-density cement slurry system will change. If the acoustic response of cement stone with normal density is taken as the criterion to evaluate the cementing quality of high density cement stone, the evaluation results obtained are inaccurate. The relationship between slurry density, curing temperature, compressive strength, sound velocity and acoustic impedance of iron powder high density cement, magnet powder high density cement and manganese powder high density cement slurry system were studied in laboratory. The results show that the compressive strength and sound velocity of high density cement paste have a linear negative correlation with the cement slurry density. The sound velocity and acoustic impedance of cement stone are the result of comprehensive factors, which are related to the type of cement slurry, water-cement ratio, cement slurry curing temperature and so on, but not only to one factor. There is a good linear relationship between the acoustic impedance of cement stone and the compressive strength of high density cement slurry system of iron powder and manganese powder, while the acoustic impedance and compressive strength of cement paste system of high density cement paste system with magnet powder show a good quadratic relationship. At the same time, the hydration products of Portland cement at high temperature were studied, and the internal mechanism of acoustic wave propagation at different temperatures was revealed. Due to the difference of acoustic properties between high density cement and conventional density cement, the evaluation standard of conventional density cement cementing quality is not suitable for high density cement cementing quality evaluation. It is necessary to introduce a sound wave amplitude reduction coefficient to correct it. By combining acoustic theoretical analysis with experimental study, the relationship between the acoustic impedance of cement stone and the amplitude reduction coefficient 桅 of high density cement acoustic wave is studied. The factors influencing the sound wave amplitude of high density cement are analyzed, and some reliable suggestions are provided for the selection of evaluation standard for cementing quality of high density cement.
