| Abstract: | The Ordovician carbonate reservoir in Middle Tarim has been damaged sometimes during exploration and development process because of its special geological characteristics and sensitivity, thus affecting normal production of oil wells. Through analysis of geological characteristics and core flow test for sensitivity, the factors, mechanism and degree of potential reservoir damage are studied. The result shows that this reservoir is strongly velocity - sensitive,strongly water- and salt - sensitive, strongly pressure - sensitive, weak - medium strong alkali - sensitive, and non acid - sensitive. |
| Keywords: | Ordovician of Middle Tarim carbonate reservoir damage mechanism damage degree experimental study |
