| Abstract: | Requirements and measures to maintain thenormal reverse circulation are discussed proceeded from theprinciple of pump suction reverse circulation. The keytechnological problem is the reasonable determination ofthe upward velocity of mixed fluid,proper control of thecuttings content in mixed fluid and right matching of thedrill pipe inside diameter with the well diameter. Methodsof deteminating the upward velocity,controlling the cut-tings content and calculating the D/d ratio are also de-scribed. |
