Description
Technical field
The utility model relates to oilfield, a kind ofly specifically carries out on-line real time monitoring, real time sample and protect Casing Failure not to be extruded or the oil-water well cover external pressure on-line continuous monitoring sampling ground installation of bad break for Casing Failure external pressure.
Background technology
In recent years, owing to strengthening oil field injection and extraction intensity, cause old filed to occur casing damage district in blocks, some block casing damage well number accounts for about 50% of total well number, and casing damage scope is in increasing trend year by year.Through investigation statistics, in the casing damage well occurred, about 60% casing deformation or the bad break position typical floor (tender two sections) in oil field, all there is typical floor (tender two sections) in most of oil field, be about between 600 ~ 1000 meters apart from the earth's surface degree of depth, and this typical floor is mainly fine and close dunn bass, there is bedding phenomenon, fine and close dunn bass does not generally seep water, but after long-term high pressure water injection, multilayer dunn bass interlayer can be made to occur cleavage phenomenon, produce slippage, the sleeve pipe at extruding or this typical floor place of bad break, causes casing damage.Due to casing repairing cost very high (general 60 ~ 1,000,000/well), cause very large waste.In order to solve typical floor casing damage problem, needing that oil-water well typical floor water quality pressure is detected and take out water quality sample and analyzing, and be at present insoluble problem to water quality pressure detecting and sampling.
Summary of the invention
Overcome existing oil field typical floor sleeve pipe easily occur extruding or bad break and need the problem that detects typical floor water quality pressure and sample to solve, the utility model provides a kind of oil-water well to overlap external pressure on-line continuous monitoring sampling ground installation, this oil-water well cover external pressure on-line continuous monitoring sampling ground installation can monitor oil-water well typical floor place water quality pressure condition, and in real time take out water quality sample, releasing pressure automatically, avoid occurring water under high pressure string and the phenomenon such as the production casing extruding that causes or bad break.
The technical solution of the utility model is: a kind of oil-water well cover external pressure on-line continuous monitoring sampling ground installation, comprise pressure measurement sampling catheter, described pressure measurement sampling catheter lower end connects pressure measurement probe tube by box cupling II, and pressure measurement sampling catheter outside is provided with pressure measurement probe tube sheath; Described pressure measurement sampling catheter top is connected with shut-in valve, and shut-in valve top is connected with threeway II; Threeway II upper interface is connected with fluid injection exhaust draining valve, and threeway II side face port is connected with pressure measxurement recorder and sample cock.
Described fluid injection exhaust draining valve top is provided with fluid injection exhaust leakage fluid dram, described threeway II side interface connects blocked valve and releasing pressure automatically safety valve successively, releasing pressure automatically safety valve is connected with threeway I, threeway I is connected to sample cock and pressure measxurement recorder.
The utility model has following beneficial effect: owing to taking such scheme, this device is connected to pressure measurement probe tube upper end, coordinate with the underground device being placed down in typical floor place, easily can be extruded production casing or bad break position is monitored, realize carrying out Real-Time Monitoring to typical floor place water quality pressure, and water quality sample can be taken out analyze, thus avoid or reduce the probability of sleeve pipe extruding or bad break.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of oil-water well cover external pressure on-line continuous monitoring sampling ground installation, comprise pressure measurement sampling catheter 16, described pressure measurement sampling catheter 16 lower end connects pressure measurement probe tube 14 by box cupling II 17, pressure measurement probe tube 14 lower end connects sampler, sampler is placed in the monitored position of typical floor, can carry out monitoring and sampling.Pressure measurement sampling catheter 16 outside is provided with pressure measurement probe tube sheath 11, what pressure measurement probe tube sheath 11 was fixed on 0.2-0.5 rice, oil-water well well head 19 lower end returns in high cement, pressure measurement probe tube 14 is fixed between production casing 20 bore hole 3, and make it fixed, in operation process, there is not loosening phenomenon.Bore hole 3 outside is provided with surface pipe 2 and conduit 1, and production casing 20 inside is oil pipe.Described pressure measurement sampling catheter 16 is transition short circuit, can be formed by connecting by a few joint conduit by box cupling I 15, and box cupling I 15 can armour tubing junction screw thread, as damage appears in conduit, can be convenient to maintain and replace.Pressure measurement sampling catheter top is connected with shut-in valve 18, when each device in shut-in valve top or tie point break down, can be closed, and is convenient to each parts keeping in repair or change shut-in valve 18 top.Shut-in valve 18 top is connected with threeway II 13; Threeway II 13 upper interface is connected with fluid injection exhaust draining valve 12, and fluid injection exhaust draining valve 12 is provided with fluid injection exhaust leakage fluid dram 10.Threeway II 13 side face port is connected with blocked valve 9, releasing pressure automatically safety valve 7 in turn, releasing pressure automatically safety valve 7 is connected with threeway I8, threeway I8 is connected to sample cock 5 and pressure measxurement recorder 6, and sample cock 5 place is provided with sample tap 4.
Under fluid injection exhaust draining valve 12 closedown and blocked valve 9 open mode, as water under high pressure string appears in monitoring point place, releasing pressure automatically safety valve 7 is opened automatically, monitoring point place water quality can be discharged, to make monitoring point place pressure be in equilibrium state, anti-sealing string hypertonia, causes production casing 20 to be extruded or bad break, underground water can be taken out by sample tap 4 simultaneously, be convenient to assay.Wherein when oil-water well normally works, the pressure change at monitoring point place, pressure measxurement recorder 6 Real-Time Monitoring underground, and automatically record pressure delta data, simultaneously before extruding or bad break appear in sleeve pipe, real-time grasp water under high pressure string stressor layer problem, and take corresponding measure, avoid or reduce the probability of casing failure.
