| Abstract: |
| Based on the lithologic and physical properties of the Bohai oilfield, the reservoir characteristics are analyzed comprehensively. Based on the characteristics of reservoir porosity and permeability, reservoir characteristics, crude oil properties and formation temperature, the reservoir characteristics of Bohai oilfield are analyzed. And the main damage factors of the oil field reservoir were analyzed by the method of pressure sensitivity, formation water composition and clay mineral analysis. The main damage mechanism and damage degree were evaluated by laboratory sensitivity test. The results show that the damage degree of reservoir sensitivity Weak sensitivity, weak acid sensitivity, weak alkali sensitivity, no speed sensitivity, the adjustment program for the region and provide the basis for efficient development. |
