Embodiment Construction
[0046] In order to make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Unless otherwise defined, all technical terms used in the embodiments of the present invention have the same meanings as commonly understood by those skilled in the art.
[0047] An embodiment of the present invention provides an automatic control system for cementing annular pressure. The automatic control system is used to control the annular pressure of the oil well annulus through a well control manifold. The well control manifold includes a kill manifold 1, a node A flow manifold 2 and a pressure gauge 3 for measuring the annular pressure, the automatic control system includes:
[0048] A pressure compensation pump 4 arranged on the kill manifold 1;
[0049] a hydraulic throttle valve 6 arranged on the throttle manifold 2; and
[0050] A pressure ...
