Description
Technical field
The utility model relates to a kind of oil and gas pipeline leakage intelligent patrol detection machine, particularly a kind of machine of patrolling and examining that can detect the oil and gas pipeline leakage position automatically.
Background technique
At present, the detecting method of pipe leakage mainly concentrates on direct leak detecting and indirect leak detecting both at home and abroad.
Directly leak detecting mainly utilizes image analysis or makes the sensor pipeline with the leakage sensitive material whether leakage is arranged outward, comprise Leak testtion cable method and air sampling method, Leak testtion cable method is along the pipeline setting with special Leak testtion cable (cable or optical cable), when pipeline takes place to leak, cable generation deterioration is also changed into electrical signal or optical signal output, promptly leaks as can be known by particular instrument and takes place.Leak testtion cable method has very high sensitivity, but there is the cost height, lacks the shortcoming of using continuity, equipment replacement difficulty, thereby limited promoting the use of of they, and the air sampling method is to detect by flame ionisation detector and combustible-gas detector, and detector is suitable for the ground detection that directly buried pipeline leaks, and is unsuitable for managing pipe laying road Leak testtion.
Leak detecting is the Operational Limits by the monitoring pipeline indirectly, estimates to leak as pressure, flow, temperature etc.Comprise: the mass balance method: judge whether to leak according to the difference in flow of importing and exporting pipeline fluid, when the leakage difference has surpassed preset threshold, think that promptly leakage has taken place pipeline, this method is owing to depend on the validity of flowmeter, so cost is higher, and can't locate leakage point; Suction wave leak detecting: at pipe ends difference setting pressure sensor, judge leakage according to the suction wave that sensor is caught, and leak according to the time difference location that suction wave arrives pipe ends, this method method is simple because of it, use at present extensivelyr, not high (positioning error can reach 100~200m/km) but only be fit to detect big leakage, Location accuracy; Pressure gradient method: the pressure gradient in entrance and outlet is made line, joint is exactly the position of leaking, but because pressure gradient along the line is nonlinear Distribution in the reality, so the Location accuracy of this method is relatively poor, and accuracy of instrument and spacing all have bigger influence to positioning result, so this method is only used with additive method as supplementary means usually; Pressure spot analytic method: carry out Pressure testing along the line by pipeline is set up an office, adopt the methods analyst checkout value of statistics, extract the data variation curve,, can carry out Leak testtion with the curve contrast of pipeline normal operating condition, this method detectable gas, liquid and some multiphase flow pipeline leak, rely on the single measuring point of analysis to measure data, realize that very easily the response time is fast, shortcoming is and can't locatees, and is poor to the evaluation capacity of leakage rate simultaneously; The statistics leak detecting: leakage causes the relation between manifold pressure and the flow velocity to change, flow velocity and pressure according to pipe ends, calculate the statistical probability that leakage takes place continuously, according to pipe ends flow velocity and pressure and assembly average estimation leakage rate, use method of least squares that no lateral is leaked and position, this method advantage is to need not complicated pipeline model, and amount of calculation is little, mounting cost is low and be convenient to safeguard that shortcoming is that wrong report easily and Location accuracy are low; Stress wave: in tube wall, propagate along pipeline with the form of stress wave in the vibration meeting that punching on the pipeline produces, highly sensitive shockwave sensor is installed on pipeline outer wall and is detected and locate leakage and punching incident by the power spectrum of analyzing stress wave signal, also can position according to the time difference that stress wave arrives pipe ends, this method shortcoming is to be difficult to find that little leakage and thick tube wall leak, Location accuracy is not high.
