Window opening of double casing in Dagang Oilfield

On October 22, 2010, in the Daqing Oilfield Block of PetroChina, the Gangshen 64-1K well required an old well modification, with a side-drilled window at a depth of 2075 meters at an angle of 46 degrees. This section of the well is a window opened between the dual casing (production casing and technical casing).

Our company has been invited to participate in the 12th China International Petroleum and Petrochemical Technology and Equipment Exhibition.

From March 19 to 21, 2012, organized by the Chemical Industry Branch of the China Council for the Promotion of International Trade, the China Petroleum and Petrochemical Equipment Industry Association, and the Petroleum Storage and Transportation Society of the Chinese Petroleum Society.

In the Changqing Oilfield of PetroChina, the accident well treatment for the Su Dong 15-36H well in the Wushenqi block involves the opening of a window in the dual-cylinder directional drilling tool with a tapered diameter.

On April 13, 2011, at the Changqing Oilfield in the Uxin Banner block of PetroChina, the Su Dong 15-36H well was treated as an accident well. The well collapsed at a depth of 3286 meters, and the casing was deformed, making it impossible to continue construction. A new side-drilling window was opened at this location to salvage the accident.
