The utility model discloses a continuous gas -liquid solid three -phase catalytic reaction kettle, including kettle body, feed pipe and discharge pipe, the kettle body top is equipped with the kettle lid, the feed pipe extends to the inner chamber bottom of kettle body through the kettle lid, the discharge pipe extends to the inner chamber of kettle through the kettle lid, the inner chamber of kettle body is installed with filter equipment, the output of filter equipment is connected to the discharge pipe, and filter equipment is placed above the liquid end of feed pipe. The filter equipment includes a plurality of filters, the filter is placed in the filter frame, the output of the filter is connected with the branch pipe, and the other end of the branch pipe is connected to the discharge pipe. The filter equipment also includes a filter frame, which is fixed in the inner chamber of the kettle body, and the filter is placed in the filter frame. The continuous gas-liquid solid three-phase catalytic reaction kettle can stably maintain uniform reaction conditions, maintain conversion rate indicators, prolong the service life of the catalyst, achieve long-period operation, and reduce equipment investment.

The present application belongs to the technical field of oil and gas testing and logging, and discloses a device and method for measuring the volume of flowback fluid in oil and gas testing and logging. The device comprises a buffer tank, which is provided with a liquid inlet, a liquid outlet, a liquid outlet and a gas release port. The liquid inlet is connected to the liquid outlet pipe of the flowback fluid, and the liquid outlet is provided with a liquid outlet pipe to communicate with the liquid pool. A partition is arranged in the buffer tank to divide the buffer tank into a first chamber and a second chamber. A liquid flow channel is arranged between the partition and the inner wall of the buffer tank to communicate the first chamber and the second chamber. A stirrer is arranged in the first chamber, and a liquid level meter is arranged in the second chamber. An electric ball valve is arranged on the liquid outlet pipe, and an electromagnetic flowmeter is arranged on the liquid outlet pipe between the liquid outlet and the electric ball valve. The present application sets the buffer tank and the partition, which facilitates the pressure relief of the flowback fluid and the obtaining of the liquid level height of the stable liquid. The present application realizes the continuous and smooth flow of the flowback fluid to achieve the purpose of accurately measuring the volume of the flowback fluid.
