Abstract
A novel ground measuring device to measure natural gas output at producing layer returned from an under-balanced drilling shaft comprises a flange, a main connecting pipe, a butterfly valve, a throttle valve pipe, an orifice throttling set, a measuring transducer interface, a bypass connecting pipe and a bypass siphon. Wherein, the flange is connected with a ground vent pipe manifold flange. The main connecting pipe is connected with the throttle valve pipe through a bolt. A middle flange is connected with the butterfly valve. In addition, the orifice throttling set is connected with the throttle valve pipe through a flange. An upper end and a lower end of the orifice throttling device are provided with a measuring transducer interface. A measuring transducer is inserted into an interface 6. Besides, the butterfly valve is connected with the main connecting pipe and the bypass connecting pipe through welding. The bypass connecting pipe is welded with the bypass siphon. The utility model removes the defect that no measuring device to measure the gas overflowed onto ground from the oil-gas producing layer in the under-balanced drilling shaft and is widely suitable for measuring natural gas output from the under-balanced drilling shaft.
Description
Technical field:
The utility model relates to a kind of under-balanced drilling pit shaft that measures and returns out a kind of novel payzone gas ground measuring apparatus that gas production is used.
Background technology:
Present domestic oil field is along with polytype hydrocarbon resources constantly is exploited, the exploratory development of low pressure and low permeability oil gas field more and more is subject to people's attention, therefore, under-balanced drilling technology has obtained unprecedented development, when opening payzone, have oil gas to flow to ground because of brill, for accurate determine gas with boring quantum of output, carry out the well control trouble free service, so designed a kind of novel payzone gas ground measuring apparatus.Domestic by retrieval correlation technique data of not seeing this device.
The utility model content:
The utility model purpose is to provide a kind of novel payzone gas ground measuring apparatus, this device solves lack in the under-balanced drilling and measure the gas flow proving installation that overflows to ground in the layer of oil gas production, can measure the gas flow that overflows to ground by this device, so that the pilot-gas quantum of output.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of novel payzone gas ground measuring apparatus is made up of flange, main connecting pipe, butterfly valve, throttle tube, throttle orifice plate apparatus, metering transmitter interface, bypass connecting pipe, bypass bend pipe; Flange is connected with ground exhaust manifold flange, main connecting pipe is connected by bolt with throttle tube, spacer flanger connects butterfly valve, flange connects throttle orifice plate apparatus between throttle tube, be provided with metering transmitter interface at the throttle orifice plate apparatus upper and lower side, and will measure transmitter and insert in its interface 6, butterfly valve and main connecting pipe and bypass connecting pipe welding, bypass connecting pipe and the welding of bypass bend pipe.To measure transmitter during work and be connected the back energized with the throttle orifice plate apparatus insertion.When carrying out the normal drilling well of gas, butterfly valve on the main connecting pipe cuts out, and at this moment gas passes through from throttle orifice plate apparatus, forms pressure reduction in the orifice plate both sides, be delivered on the metering transmitter by metering transmitter interface, and its pressure difference signal is changed into discernible signal output promptly obtain the gas yield data.
The new beneficial effect of this practicality is simple in structure, is convenient to maintenance and uses, and cost is low, this device solves the problem that payzone gas can't be measured in the under-balanced drilling, and improved the well control degree of safety.
Description of drawings:
Accompanying drawing is the utility model one-piece construction synoptic diagram.
Among the figure, 1, flange, 2, main connecting pipe, 3, butterfly valve, 4, throttle tube, 5, throttle orifice plate apparatus, 6, metering transmitter interface, 7, bypass connecting pipe, 8, the bypass bend pipe.
Embodiment:
As shown in the figure, a kind of novel payzone gas ground measuring apparatus is made up of flange 1, main connecting pipe 2, butterfly valve 3, throttle tube 4, throttle orifice plate apparatus 5, metering transmitter interface 6, bypass connecting pipe 7, bypass bend pipe 8; Flange 1 is connected with ground exhaust manifold flange, main connecting pipe 2 and throttle tube 4 are connected by bolt, spacer flanger connects butterfly valve 3, flange connects throttle orifice plate apparatus 5 between throttle tube 4, be provided with metering transmitter interface 6 at throttle orifice plate apparatus 5 upper and lower sides, and will measure transmitter and insert in its interface 6, butterfly valve 3 and main connecting pipe 2 and bypass connecting pipe 7 welding, bypass connecting pipe 7 and 8 welding of bypass bend pipe.
