Research On Safety And High-efficiency Drilling Technology In Daqing Chaoyanggou Oilfield

With Chaoyanggou oilfield waterflooding into the later stage, resulting in abnormal formation pressure zone increased significantly, to Chaoyanggou oilfield drilling presented a huge challenge. In order to enable safety and high-efficient drilling and ensure Chaoyanggou oilfield development affected, particularly for Chaoyanggou oilfield in high pressure, big angle, ultra-low permeability and other characteristics, developed for the block drilling of a mature technology become guaranteed Chaoyanggou oilfield development is the key. This study is aimed at Chaoyanggou oilfield drilling is slow, the drilling cost is high, on the basis of actual research and theoretical analysis, to carry out safety and high-efficient drilling technology research. Based on the existing drilling equipment, by the original drilling advanced and mature technology to optimize the combination study, integrated applications,and be innovative, it formed a set of high formation pressure in Chaoyanggou oilfield,drilling angle and other characteristics supporting technology, this technology in Chaoyanggou oilfield application confirmed rate of penetration greatly improved drilling cycle was shortened, well drilling cost savings. safety and high-efficient drilling technology is not a single theory or technology breakthroughs, but preferred characteristics for Chaoyanggou oilfield in advanced and suitable drilling technology, and combine, through a variety of integrated application of drilling technology to improve the rate of penetration, it no additional equipment or large-scale transformation of the existing equipment, with targeted, small investment, quick, significant economic benefits features.
