Описание: Primary cementing is the process of placing cement in the annulus between the casing and the formations exposed to the wellbore. The major objective of primary cementing has always been to provide zonal isolation in the wellbore of oil, gas, and water wells to exclude fluids such as water or gas in one zone from oil in another zone. To achieve this objective, a hydraulic seal must be obtained between the casing and the cement. And between the cement and the formations, while at the same time preventing fluid channels in the cement sheath. This requirement makes primary cementing the most important operation performed on a well. Without complete zonal isolation in the wellbore. The well may never reach its full producing potential. Remedial work required to repair a faulty cementing job may do irreparable harm to the producing formation.

Описание: Well completion engineering is an important component part of oil and gas well construction and a basis of field development implementation. It has a goal of ensuring regular and safe production and prolonging the production life of oil and gas wells. The traditional mode of well completion engineering, which had been adopted in China for a long time, cannot meet the requirements of developing circumstances; thus, reform is needed. After summing up domes-tic and foreign experience and lessons, the new Advanced Well Completion concept has been presented. Based on field geology and reservoir engineering, it adopts the nodal analysis method, and drilling, well completion, and production are organically integrated, thus forming an integrated well completion engineering system.
