Application of screen top double stage cementing in Dubai Kazakhstan

Nature fractures scattered in Dubai oilfield and well-developed micro fractures cause poor bearing capacity of formation and long cementing section. Many wells treated by conventional cementing method still encounter serious leakage even though the mud density adjusted in certain degree. So the cementing quality is unable to obtain guarantee. Aiming at the cementing problem in this block, screen top double stage cementing technology was introduced to solve this leakage problem effectively. Based on the supporting tools and construction technology of screen top double stage cementing, the applicable well condition, construction process and related technology and tools of this type cementing method were recommended to provide a useful reference for similar well construction.
