The Polymer Cement Fluid Loss Reducer in Haita Region

Abstract

The underground situation of Haita oil field is complicated, the chasm develop better, prone appear card and collapsed situation in drilling process. Formation dip larger and prone appear well deviation in drilling process, repeatedly corrected well deviation cause the quality of well bore worse, leading to a large segment of "pregnant", "the candied fruit" well hole. Well diameter irregular and well bore quality assurance is not easy, bring difficulty on ensure cementing project quality. Statistics substandard quality cementing wells during drilling, the average single well corrected well deviation up to 3 times. The oil well cement fluid loss reducer of our country experiencing imitation, self-study and self-improvement process. Especially since the 1990s, the research and application of domestic oil well cement fluid loss reducer rendered vitality, a series of fluid loss reducer products gradually replace foreign products.
