摘要
Abstract
Because of low fracturing pressure in Rumaila formation, leakage is easy to happen in the intermediate casing ce-menting procedure;the shale development in production layer leads to irregular chambering and shrunk holes; cementing displacement efficiency is low and it is difficult to guarantee cementing quality.In late well cementing construction, the for-mation characteristics are analyzed starting from several key factors that affect the cementing quality to optimize the techni-cal measures of plugging and by cementing design software to optimize the number of casing centralizer;through indoor test, inhibited weighted drilling fluid is optimized to control and adjust the performance parameters of drilling fluid used in unsta-ble shale layer, the API fluid loss is controlled at 4mL and density 1.35g/cm3.A set of comprehensive cementing technol-ogy is formed, the cementing qualified ratio reaches to more than 80%in field tests.关键词
