During the logging work of the foreign cooperation mudlogging projects, the description of drillling cuttings (sample) required by the foreign companies is quite different from what we did at home. This paper is intended to give some ideas of description of sample at wellsite with the reference of the guidance of standards of several foreign companies and the working experiences of the author, also some problems that the geologists should pay attention to during the description of sample at wellsite.展开更多

Because of the complicated distribution of remaining oil and great difficulties of potential excavation, effective succeed development methods are in urgent. Through physical modeling in lab, field experiments and industrial deployment, a set of necessary industrialized technology is posted, which is suitable for terrestrial fluvial delta reservoirs during super high water bearing stage, including the detailed description of major reservoir, remaining oil monitoring, fine potential exploitation by water flooding and IOR technology by chemical flooding. This technology has been applied to Shengli, Zhongyuan and Henan oilfields with remarkable benefits and social effects.展开更多
