The invention discloses a plug-in blowout
wellhead crude oil collecting device. The plug-in blowout
wellhead crude oil collecting device comprises a central
pipe, a connector mechanism, a
hydraulic cylinder mechanism, a slip mechanism, a
capsule sealing mechanism, an interference sealing mechanism and a guide mechanism. The invention further discloses a blowout
wellhead crude oil collecting method. The method comprises the following steps that firstly, the matched extension pipeline, the
blowout preventer device, the hydraulic valve and the collecting pipeline are selected; secondly, a central
pipe, an extension pipeline, a
blowout preventer device, a hydraulic valve and a collecting pipeline are fixedly connected in sequence; thirdly, the connector mechanism and the hydraulic valve are connected with the hydraulic
station; (4) the device is placed at a proper position in a sleeve; fifthly, the slip mechanism is fixed in the casing
pipe in a fastened mode, it is ensured that the
capsule sealing mechanism and the interference sealing mechanism are both tightly sealed on the casing pipe, and then crude
oil can be collected. The device is reasonable in structure, high in practicability and capable of reducing the risk that crude oil pollutes the environment and improving the efficiency of emergency operation.
