Research Of Enhancing Tertiary Infilling Adjustment Wells' Cementing Quality

Abstract: Daqing oil field has been in later exploitation, the pressure of under ground reservoir more and more complex and the contradiction that pressure difference is large between formations bigger and bigger. So it required that the cementing quality of tertiary infilling adjustment wells is well. The aim of this article is to enhance the tertiary infilling adjustment wells'cementing quality. Through researching the relationship between the solidification characteristic of cement and the oil and gas channel, using the technology of tertiary infilling adjustment wells'pressure forecast, through this research, it attains to forecasting the formation pressure accurately and guides controlling the formation pressure. Researching the solidification characteristic of the cement, it selects the appropriate system of cement. Using the shaking cementing technology, it looks for the approach of enhancing tertiary infilling adjustment wells'cementing quality.
