Integrated wellhead device for filtering injected and produced gases

An integrated wellhead device for filtering injected and produced gases, comprising a horizontal tank and spacer plates inside the horizontal tank, wherein the spacer plates divide the internal space of the horizontal tank into an upper space, a lower space and a right space, the upper space and the lower space are connected to the right space, and an injected gas filtering system and a produced gas filtering system are provided in the horizontal tank;

• the injected gas filtering system comprises an injected gas inlet, an injected gas channel, an oxygen removal chamber, and an injected gas outlet that are connected in sequence;
• the injected gas inlet is fitted on the top of the horizontal tank, the injected gas channel penetrates the spacer plate and is connected with the oxygen removal chamber located in the lower space, and the injected gas outlet is fitted at the bottom of the horizontal tank;
• the produced gas filtering system comprises a filtering system, a quasi-overpressure gas direct drainage system, and an overpressure gas direct drainage system;
• the filtering system comprises a produced gas inlet, a gas deposition chamber, a gas removal chamber, a gas retention chamber, a gas acceleration channel, and a produced gas outlet that are sequentially connected;
• the gas removal chamber comprises oxygen removal chamber two, sulfur removal chamber and carbon dioxide removal chamber that are connected in any order;
• the right space is the gas retention chamber;
• the produced gas inlet is located at the top left end of the horizontal tank, and the gas deposition chamber and the gas removal chamber are located in the upper space, the gas acceleration channel is arranged in the lower space and penetrates the gas removal chamber one, and the produced gas outlet is set at the left end of the horizontal tank;
• the gas deposition chamber is provided with a pressure monitoring device;
• the quasi-overpressure gas direct drainage system comprises a gas flow channel, a safety ball valve, a spring one, a spring fixing block one, and a quasi-overpressure gas direct drainage channel that are connected in sequence;
• the spring fixing block one is set on the spacer plate, and the quasi-overpressure gas direct drainage channel is connected to the gas retention chamber;
• and
• the overpressure gas direct drainage system comprises a safety floating plate, a safety spring, a safety baffle, an overpressure gas drainage chamber, and a safety gas outlet that are connected in sequence;
• the safety baffle is provided with a overpressure gas drainage channel;
• the safety floating plate is cut from the spacer plate, the safety baffle is located in the lower space facing the gas deposition chamber, a gap is left between the safety baffle and the spacer plate to provide a gas flow channel when the gas is overpressured, and the safety gas outlet is arranged at the bottom of the horizontal tank.
