Abstract
The invention relates to a gas well testing safety monitoring and controlling technology. The gas well testing safety monitoring is that data, such as pressure, temperature and oil, gas and water yield of a well mouth, a throttling testing manifold, a heater, a separator and the like can be monitored in real time and automatically collected and recorded by a data acquisition system, and over-limit alarm is realized; the real-time monitoring, the automatic acquisition, the data recording and the over-limit alarm of harmful gases, such as hydrogen sulfide, carbon dioxide and methane in well site air are realized; and real-time video monitoring in field and the like can be realized. The gas well safety monitoring and controlling technology disclosed by the invention aims to carry out pressure, temperature and flow monitoring and automatic alarm on the well mouth, a casing pipe hohlraum, an upper and lower flow of an oil nozzle, a heater, a separator and toxic, harmful gas and the like, whole-area video area monitoring is realized, the field technology measure is guided, multiple parameter curves are displayed in the same screen, data is synchronously printed and drawn, and therefore the data is safely monitored and completely and accurately obtained.
Description
Affiliated technical field:
The present invention relates to a kind of gas well test safety monitoring and control technology, belong to technical field of petroleum extraction.
Background technology:
Existing gas well test safety monitoring and control technology, there is following difficult point in the irrationality because of its safety monitoring and control technology: (1) safety monitoring function, safety monitoring technology measure must be rationally reliable, perfectly safe; (2) how to carry out choke pressure drop distribution, heating, dosing and could prevent effectively that stagnant ice is stifled; When (3) superpressure appears in ground flow, how to carry out automatically unloading, ice occurs when stifled, how safe and effective enforcement de-plugging guarantees that ground flow reaches test safely and carries out smoothly; When (4) natural gas leaking occurring, how to guarantee the safety of personnel and equipment; (5) how to realize safety monitoring and control interlock automatically, make safety monitoring and security control synthesize a reliable system.Gas well test safety monitoring process proposes to use the multiple means comprehensive monitoring, comprehensively carries out accident monitoring and prediction.The maintenance data acquisition system realizes the real-time monitoring of data such as well head, throttling test manifold, heater, eliminator equal pressure, temperature, oil gas aquatic products amount and collection and typing automatically, overload alarm; Realization is to the real-time monitoring of pernicious gases such as the airborne hydrogen sulfide in well site, carbon dioxide, methane and gather and logging data overload alarm automatically; Realization is to on-the-spot real-time video monitoring
Summary of the invention:
The objective of the invention is in test process, dirty on well head, casing annulus, the oil nozzle, heater, eliminator, toxic and harmful etc. be carried out the monitoring of pressure, temperature, flow, automatically report to the police, region-wide video monitoring, instruct on-the-spot technological measure, the multi-parameter curve shows with screen, data isochronous printing and drawing reach safety monitoring, get and get accurate data entirely.
The present invention is achieved through the following technical solutions, specifically comprises the steps:
Ground flow is formed.Comprise: main testing process; Secondary testing process; Straight-through open flow flow process; Sleeve pipe open flow flow process; Circulation kill-job flow process; Data Collection ﹠ Processing System; The emergent control system of safety
Safety monitoring.Safety monitoring comprises the real-time collection monitoring to 20 several data such as pressure, temperature, fuel gas, CO2 gas, H2S gases, and the monitoring flow process comprises four buses, is respectively pressure and temp bus, fluid flow bus, leakage gas bus and video bus.
Safety control system.Control system comprises down-hole, well head, surface safety valve (SSV).Storm valve is installed in apart from the position of well head 100m, liquid controling pipe line passes through from the oil jacket annular space, and well mouth release valve is christmas tree secondary main valve, surface safety valve (SSV) be installed in well head between the choke manifold near well one side, all adopt the hydraulic pressure Long-distance Control, down-hole, well mouth release valve also have fusible plug control.
Beneficial effect:
In test process, dirty on well head, casing annulus, the oil nozzle, heater, eliminator, toxic and harmful etc. are carried out the monitoring of pressure, temperature, flow, automatically report to the police, region-wide video monitoring, instruct on-the-spot technological measure, the multi-parameter curve shows with screen, data isochronous printing and drawing reach safety monitoring, get and get accurate data entirely.
The specific embodiment:
The well head control system; Christmas tree or control head control contain the flap type that surges.
Surface safety valve (SSV); The flap type that surges is installed between well head and the throttling test manifold.
The throttling test manifold; Comprise positive choke and adjustable bean.
Heater; It is dirty generally to be installed in the throttling test manifold, if pressure rating allows, also can be installed in throttling test manifold upper reaches, heater generally has the second throttle function, generally be to come throttling by the needle-valve that is installed on the heater, be not higher than 0.546 times of oil nozzle upstream pressure as long as guarantee the oil nozzle downstream pressure, just can not exert an influence to gas production.
Eliminator; Two-phase or three phase separator are installed in heater or the throttling test manifold is dirty, are typically equipped with gas flowmeter fluid flowmeter, the output that can be used for measuring oil, gas, water on the eliminator.Most of eliminator also is equipped with automatic control system, generally realizes by the air bladder valve, can realize automatic drain, automatically regulatory function.
Surge tank; Be connected the effect of get up buffering and metering liquid output with the eliminator tapping line.
The combustion combustion system; The gas well test of asking product for not entering the station, natural gas can only be burnt, and is finished by combustion system, constitutes by burning tube and igniter.
The throttle well killing manifold; Be connected on oil pipe and the sleeve pipe, be used for throttle well killing, import connects ball-and-seat, the outlet noticeable degree, and much the throttle well killing manifolds need not reconnect pipeline, just can realize the circulating with choke kill-job.
Mud circulating system; Preparation, storage mud, well killing fluid, tubing flow displacement liquid etc.
Data collecting system; Gas well safety monitoring main equipment can realize enrolling data such as pressure, temperature, output, can also detect fuel gas, toxic and harmful etc., simultaneously can also realize data analysis and processing, and overload alarm is with function such as automatic control system interlock.
