Drilling in the most deep well of fukushan oil field by the Great Wall drilling
CNPC news February 6th, by the the Great Wall drilling engineering company, the engineering institute has undertaken the drilling engineering design and technical support of Fushan oilfield risk exploration well, Hua Shen 1X well has been drilling successfully, and is currently drilling normally.
The well is the first risk exploration well in Fushan oilfield since its exploration and development in 1985. It has the deepest well depth, the largest closed displacement and the predicted bottom hole temperature exceeding 190 degrees Celsius. The success of this well drilling exploration of Fushan oilfield flower field north shallow reservoir area and oil and gas situation, the implementation of key exploration areas in the next step, explore the mode of flower field Beiliu two lithologic reservoirs and three tectonic lithologic reservoirs played an active role in promoting.
Take a deep 1X well design of cable 5713 meters deep, 4517 meters deep vertical design, the maximum deviation wells 42.98 degrees, the maximum displacement of the bottom closure of 3208 meters, is a long cementing section, offshore mining, reservoir for playing special wells. At the same time, the well is also a drilling well designed by the drilling engineering design supervision center of the Great Wall Drilling Engineering Institute, which has the deepest depth, the largest displacement and the difficulty of construction. In April 2017, researchers from the design center of the Institute of engineering began to prepare for the design of the well, and put forward a series of drilling technology programs, such as well structure, well trajectory and drilling fluid.
