The specific embodiment
With reference to figure 1, near the well head that high-integrity protective system (HIPS) 10 is installed in the plumbing system so that from well head 102 transmit pressurization fluid product (such as, oil or gas) by pipeline 104 to main place at a distance.HIPS has the entrance 1 that is connected to well head pipeline 102 and the outlet 2 that is connected to plumbing system 104, and liquid product enters and leave HIPS10 by this entrance and exit.Preferably, in order to be transported to the well head place, and if necessary, HIPS is provided with suitable flange and adapter to HIPS by skid, in order to be attached to the entrance and exit of oil field pipe.
Two groups of disconnecting valves (ZV) 11,12 and 13,14 are communicated with entrance 1 and outlet 2 fluids, therefore can operate the path as fluid product.Identified and be called each group in the ZV group of ZV-1 and ZV-2 and have respectively two ZV11-12 and the 13-14 that is connected in series.ZV is autoshutdown when not supplying electric power, and is maintained in the open position by traditional hydraulic-driven actuator or driven by power actuator, avoids the abnormal operation situation with protection downstream line system 104.
Two exhaust-control valves (VCV) 41,42 respectively with two groups of ZV11, the pipelines in the middle of 12 and 13,14 connect, and are communicated with discharge pipe 106 fluids.Discharge pipe 106 is communicated with fluid reservoir 70 fluids, and this fluid reservoir is as the collection system case of sealing.Alternatively, discharge pipe can lead near the burn pit (not shown) in well site.VCV41,42 can be discharged to the pressure fluid between two ZV in the discharge pipe 106 when they are opened.Valve 71,72 and 81 is controlled the hydraulic pressure supply of being undertaken by pressure reservoir by their opening and closing operation.When valve 81 is opened, force fluid to leave storage 70 from the pressurized nitrogen of case 80, and enter the HIPS pipeline or via valve 72 in order to its with or dispose.VCV41,42 will be discharged in the discharge pipe from the pressure fluid between two ZV when they are opened.Pressure-sensing transmitter 54,55 between the corresponding ZV to determine the fluid pressure between two ZV.Alternatively, can 54 and 55 places be installed by a plurality of pressure-sensing transmitters in the place, to guarantee reliability and for subsequent use as test macro.
Pressure-sensing transmitter 51,52,53 is installed in outlet 2 upstreams to monitor from exporting 2 fluid pressures that leave HIPS.Three transmitters are monitored by security logic solver 31.If any two of three transmitter 51-53 sense pressure and are elevated on the predetermined threshold, then logic solver 31 makes the well autoshutdown by ZV11-14, therefore protects the downstream pipeline to avoid excess pressure.
The security logic solver 31 that is preferably the software module that programming is good in advance in computing machine etc. connects by hardwire or by radio transmitters and ZV11-14, VCV41,42 and pressure-sensing transmitter 51-55 communicate by letter.31 generations of security logic solver and transmitted signal are with control ZV11-14 and VCV41,42 operation.Carry out control based on the pressure data from pressure-sensing transmitter 51-55.
Hand valve 61-64 be installed in entrance 1 and export 2 and ZV11-14 between with in the situation that urgent with the isolation of two groups of ZV11-14 and plumbing system, also so that this system can manually be closed in order to keep in repair and/or change its any parts.
All valves are by operating such as those conventional valve actuators (not shown) of knowing in this technical field.Valve actuator and pressure sender 51-55 have self diagnostic capability and any fault communication that will detect to security logic solver 31.
The method that is used for closing test and total travel test according to of the present invention is described with reference to Fig. 2.Before beginning this test, carry out the safety inspection of HIPS plumbing system.If fluid pressure surpasses predetermined threshold levels (S10), then close all ZV(S20).Otherwise, close first group of ZV11,12, and second group of ZV13,14 stay open (S30).
Then, open first group of ZV11,12 with setup test second group of ZV13,14(S40).Determine at second group of ZV13,14 close test period as first group of ZV11 of fluid path, whether 12 open (S50) fully.If first group of ZV11,12 do not open fully, start alarm signal and stop this test (S60).If first group of ZV11,12 open fully, then close second group of ZV13,14(S70).Check to want tested ZV13,14 close fully in order to prepare closely to close test (S80).If ZV13,14 do not close fully, then start alarm signal (S90) and stop test.
If ZV13,14 close fully, then begin ZV13,14 closely close test.Be positioned at second group of ZV13, the VCV42 in the middle of 14 are opened with ZV13, and the pressure between 14 is reduced to stationary value (S100).
Then close the pressure sealing (S110) of VCV42 and inspection VCV42.If VCV42 does not close fully, perhaps this valve leaks so that the pressure in the discharge of pipes section between valve reduces continuously, then starts alarm signal (S120) and takes suitable remedial action.If VCV42 closes fully, then measure ZV13, the pressure between 14 (S130).Closely closing test period, ZV13, the pressure between 14 monitor by pressure sender 55 continuously, and the result is sent to security logic solver 31, until closely close the test end in period (S140).
Fig. 3 is to scheme to express the data of closely closing the test period acquisition under two kinds of different situations.When VCV42 opens, ZV13, the pressure between 14 is reduced to lower pressure from routine operating pressure, and VCV42 closes fully.If ZV13, the pressure between 14 raises, and this is considered to be in ZV13, has the evidence that leaks in one or two of 14.Because some micro-leakages may be acceptable, therefore must determine during the period of closely closing test or whether pressure increases or pressure increases afterwards speed surpasses predetermined threshold levels (S150).If pressure is elevated on the threshold level during test period, this indicates ZV13,14 the ability of taking a seat et out of order, and security logic solver 31 starts alarm signals so, informs ZV13,14 the fault of closely closing test (S160).If during test period, the pressure increase is no more than threshold level, second group of ZV13 then, 14 by closely closing test.At ZV13,14 closely close test period, first group of ZV11,12 are shown in an open position, for production provides flow path (S170).For the completion system function test, by closely closing second group of ZV13 of test, 14 are opened again, and as fluid path (S180).
As from top description with obvious, use substantially the same methodology to test first group of ZV11,12.
The present invention makes HIPS can be used as continuously fluid path carrying out closely to close when test with total travel, and the while can be taked any necessary protection behavior.Even the automatic operation of being carried out by the security logic solver guarantees also will be performed in test period emergency cut-off condition.The record of test is stored, and can recover later on or electronically and/or show or as table data with the graphic form of printing.
