ZPEB Drilling is one of the strongest onshore drilling forces in China and is composed of 5 specialized drilling companies, 1 drilling engineering service company and 1 drilling engineering research institute. ZPEB Drilling owns more than a hundred mechanical and electrical rigs of various kinds which include, but not limited to, electrical rigs of C-3-II, C-1-II, E2100, E1700, 50DB, ZJ-50D & ZJ-70D, and mechanical rigs of F-400, F-320, ZJ-45J, ZJ-32J and truck-mounted rig of ZJ-20, etc.. Among the drilling crews of ZPEB, 30 crews have been granted the titles of National Gold Medal Crews; 31 crews have been granted Qualification Certification of Class A by CNPC, the rest crews have all been granted Qualification Certification of Class B and 7 crews have acquired the qualification for drilling coal-bed methane wells. ZPEB Drilling has obtained ISO9000 Quality System Certification and enjoyed the membership of both International Association of Drilling Contractors (IADC) and International Well Control Forum (IWCF).
ZPEB Drilling has accumulated rich experience through many years’ drilling activities in various complicated reservoirs, and has led the way in China in terms of drilling directional well, cluster-well, horizontal well, ultra-deep well, salt-gypsum bed and reservoirs of high-pressure and low-permeability, and also in the technologies of well control, lost-circulation control and sealed coring. Up to now, not only has it successfully drilled a lot of wells in Zhongyuan Oilfield, a typical oilfield with complex geological settings, such as faulted blocks, deep-buried hydrocarbons, overdeveloped salt gypsums, abnormal high pressure, and being prone to blowout, circulation loss and stuck, etc., but also has offered drilling services to many domestic major oilfields and foreign oil companies. Till now, many world-level drilling records have been created and several hundred wells with depths of over 5,000m have been drilled, including the well of China Continental Exploratory Scientific Drilling (Well No.1 CCSD). In addition, ZPEB Drilling has actively participated in the drilling of non-petroleum wells, such as coal-bed methane well, water well, geothermal well and saline-alkali mirabilite well.
ZPEB Drilling has successfully accomplished many international drilling projects by means of its high-quality drilling crews, up-to-date drilling equipment and technologies, and has been granted the title of “the Company Undertaking the Most of the Onshore International Drilling Projects in China” by the Market Development Center of the State Council of China.
