Abstract
A natural gas tester is provided for testing the productivity of natural gas, belonging to the technical field of fabrication of test equipment for drilling and completion of natural gas exploration. The utility model comprises a straight tube mechanism and a bypass mechanism. A retractable adapter is arranged inside the straight tube mechanism and connected with a detachable connector via a punctured plate. The bypass mechanism is provided with a bended member connected with T-shaped adapters at the two ends of the straight tube mechanism. The bypass mechanism is connected with a fast-mount adapter. The utility model provides a retractable adapter for implementing a natural gas tester capable of the rapid change of porous plate. The utility model solves the problems of the prior art, such as large consumption of various parts, long assembly time for porous plate exchange, and heavy load of assembly and disassembly. The utility model realizes the connection between the straight tube mechanism and the bypass mechanism by using a bended tube and the retractable adapter; reduces the weight to 1/6 of the prior art, fabrication cost by 50%, installation time by 7/8, and porous plate exchange time to 1/6 of the prior art; reduces the labor intensity for transportation and installation; and reduces the probability of injury to the staff.
Description
Technical field:
A kind of rock gas proving installation is used for the test to the gasser production capacity, belongs to the manufacturing technology field of rock gas well completing test equipment.
Background technology:
In the prior art, after a bite gasser is finished drilling well, in the process of completion formation testing, in order to determine the gas production of this well, need to adopt special testing apparatus that the flow of rock gas is tested, the equipment that prior art is used to test mainly is the critical velocity flowmeter that adopts perforated plate, in test process in order to survey the output of accurate rock gas, must change the orifice plate of respective aperture on proving installation tests, two kinds of proving installations are arranged at present: a kind of is the proving installation of not being with by-pass pipe, when changing orifice plate, opens emergent open flow igniting flow process, close testing process and change orifice plate, its problem is: adopting this mode to test needs to use 20 in oil pipe, and proving installation need be fixed 14 places, and the replacing orifice plate time needs 30min, and the use accessory is many, and dismounting and the workload of installing are big; Second kind is the proving installation of band by-pass pipe, this prior art is when changing orifice plate, to open by-pass valve earlier, close upper and lower two valves of critical velocity flowmeter then, open orifice plate again and connect the replaceable orifice plate of trip ability in the ninth of the ten Heavenly Stems, its shortcoming is: use this test mode need use 10 in oil pipe, the position that proving installation need be fixed is 7 places, the elbow that connects by-pass pipe is to be made of two joints and a connector, therefore the accessory that needs is various, the built-up time of device needs 4 hours, and dismounting and the workload of installing are big, and the replacing orifice plate time also needs 30min.
Goal of the invention: the purpose of this utility model is the shortcoming at prior art, adopts the mode of simplifying combination, and a kind of collapsible joint that has is provided, and can realize changing fast the rock gas proving installation of orifice plate.
The utility model is achieved in that the utility model comprises straight tube mechanism and bypass mechanism, and straight tube mechanism comprises that the ninth of the ten Heavenly Stems is swum in two valves, expansion joint, orifice plate connection, manage at the upper reaches; Bypass mechanism comprises two bend pipes, a valve and a ready-packaged joint; Two valves in the straight tube mechanism are arranged on the inboard of two bend pipes, and expansion joint is arranged on orifice plate and connects the trip dirty part in the ninth of the ten Heavenly Stems, and the upper reaches pipe is arranged on orifice plate and connects the trip upper reaches part in the ninth of the ten Heavenly Stems; The ninth of the ten Heavenly Stems is swum in upper reaches pipe, orifice plate connection, expansion joint all is arranged between two valves; Two bend pipes of bypass mechanism are connected with the T junction at straight tube mechanism two ends respectively, and a valve and a ready-packaged joint are set between two bend pipes; During use, the upper and lower end interface of this device straight tube mechanism is connected on the relief line, when testing, close the bypass mechanism valve earlier, open two valves of straight tube mechanism, rock gas flow to the open flow lighting-up tuyere by orifice plate in the straight tube mechanism and expansion joint, so just can record the flow of rock gas; When needs are changed orifice plate, open the valve on the bypass mechanism earlier, close two valves in the straight tube mechanism, rock gas just flows to the open flow lighting-up tuyere from bypass mechanism, opens the orifice plate connection then and swims the ninth of the ten Heavenly Stems, take out orifice plate, change required orifice plate, tighten the orifice plate connection and swim the ninth of the ten Heavenly Stems, open the valve at straight tube mechanism two ends again, close the valve on the bypass mechanism, just can recover test job.
Advantage of the present utility model and effect are, the bend pipe that is used to connect straight tube mechanism and bypass mechanism does not need joint, replaced by the expansion joint of activity and to be fixedly coupled pipe and joint, therefore various connection fittings have been reduced greatly, weight drops to 40 kilograms from 240 kilograms of prior art, manufacturing cost has reduced more than 50%, the time of erecting equipment is 1/8 of prior art, the time of changing orifice plate in the test process is original 1/6, has to reduce the worker and remove the feature that peace labour intensity and minimizing personnel injure probability.
