Abstract

A novel segmented combined type multifunctional high-pressure rotary control head disclosed by the present invention comprises a control seat, a top sleeve and a sealing mechanism, the control seat comprises a base and an air guide sleeve, the air guide sleeve is installed in the middle of the upper end face of the base, the air guide sleeve is vertically and fixedly connected with the base, the top sleeve is installed on the upper end face of the air guide sleeve, and the sealing mechanism is installed on the top sleeve. The top sleeve is fixedly connected with the gas guide sleeve, the sealing mechanism is installed in the middle of the top sleeve, and the sealing mechanism is fixedly connected with the top sleeve, so that it is guaranteed that the gas guide sleeve can be stably installed on the upper end face of a wellhead through the base when a user needs to use the gas guide sleeve, and it is guaranteed that the user can install the gas guide sleeve through the base for use; a user can conveniently cooperate with a wellhead for connection and exhaust through the sleeve, the user can stably install the matching sleeve on the sleeve to ensure that the top sleeve is stably installed for use during use, and the user can conveniently install the lower ring sleeve at the upper end of the matching sleeve for cooperative use.

Description

technical field [0001] The invention relates to the technical field of oil well control equipment, in particular to a novel segmented and combined multifunctional high-pressure rotary control head. Background technique [0002] Oil wells are holes drilled according to the well layout system of the oil field development plan for the exploitation of oil, and the passage of oil rising from the bottom of the well to the well head is the hole drilled by the drilling method. Generally, after the oil well is drilled into the oil layer, the oil layer casing is lowered, and oil well cement is injected into the annular space between the casing and the well wall to maintain the well wall and seal the oil, gas, and water layers. The hole gun shoots through the oil layer to form a channel, which is lowered into the oil pipe, and the oil is raised from the bottom of the oil well to the head of the well by a suitable induction method. [0003] The inventor of the present application found...
