| An Integrated Analysis of Water Flushed Formation of the Weixing Oilfield |
| The Weixing Oilfield is a new oil field reported by the Limited Liability Company. As the oilfield was discovered not long ago, and its development cycle is short, the information on the reservoir description and formation water flooded degree are very insufficient. In order to check the formation water flooded degree and distribution of remaining oil of various Putaohua reservoirs under the current well network condition, the authors deployed a confined coring well-examination. Based on the analytical data of oil-based mud coring and confined coring in the early production or pre-production stage, this paper made a preliminary evaluation of the reservoir, and analyzed the washing degree through identifying and calculating flooding. The result shows that Putaohua reservoir has the following characteristics: irreducible water saturation is relatively low, oil and water seepage range is wide, flooding degree is low, washing thickness is thin, washing degree is medium, and well producing degree is low. |
