The Study of Sedimentary Facies in Daqing Oilfield from the Perspective of Science of Science

The sedimentary facies research in Daqing oilfield has gone through a process of generating ideas, conducting research, and achieving results, the achievements of which have been widely applied in oilfield production1. The research is a very typical case in the history of petroleum science and technology with strong science of science significance, which is in conformity with the universal law of science of science on the emergence, development and maturity of new science and technology. It came into being along with the actual needs of the development and production of Daqing oilfield，and was gradually formed and has been gradually improved through step by step exploration and accumulation under the guidance of scientific methodology. The principle of science of science points out that there are three necessary conditions for the existence and development of a new theoretical doctrine, the case of Daqing oilfield fully complied with the principle: it not only contains the scope of the original theory, but also can solve the problems that the original theory are unable to solve, and may further predict the future development, so it has a strong vitality. Meanwhile，science of science also points out that it is almost impossible for a new science and technology to emerge smoothly without obstacles and setbacks. This study is just such a case, which was initially accused of heresy, not accepted by some authorities. However, after being tested through repeated practice, it has finally established its status, and has still been playing an important role in the development process of Daqing Oilfield.
