Description
Technical field
The utility model relates to a kind of holder barrel structure; be applicable in the industries such as oil, petrochemical industry; a kind of at the medium-term and long-term holder cylinder that is placed on down-hole protection downhole testing device of oil well production well logging, the one point sensing device holder cylinder of especially a kind of fiber optic temperature and pressure permanent oil well sensing specifically.
Background technology
Smart well technology starts from the nineties in 20th century, improves under the main trend of oil reservoir production capacity at that time Global Oil industry, and smart well technology is developed and commercialization.The research and development of this technology make many original unworkable marginal oil fields obtain exploitation, for the exploitation of deep water, sea, outlying district and old filed has brought hope.So-called smart well is exactly that sensor, the data transmission system that can obtain down-hole oil gas production information unify control appliance and the well that can carry out on ground Data Collection and decision analysis have been installed in well.Can carry out Long-distance Control by smart well, reach the purpose of optimizing production capacity.Use smart well technology and can carry out Long-distance Control, the cross flow one of avoiding different reservoir pressures to bring to inflow and the outflow of a plurality of reservoir fluids by a bite well.Adopt for heavy wool is laminated, the application of intelligent well completion allows alternately to exploit the upper and lower payzone, has accelerated the speed of production of whole well, has also improved the net present value (NPV) of oil well.The telemanagement of oil reservoir has reduced the cost of potential workover treatment so that the operating personnel need not well is carried out physical interventions.Under the condition of rig time (especially in deep water or seabed) cost costliness, the reduction of workover cost can bring significant benefit, has also remedied the output of losing owing to well workover simultaneously.In addition, the Injection Well of using intelligent well completion can carry out water filling control better, improves the ultimate recovery of oil well.Simultaneously, using the smart well system also can reduce the surface based construction and execute cost.The purpose of smart well technology is to improve the oil mining rate, and the control of raising oil field automation is transversely arranged, reduces oilfield operations cost and equipment cost, thereby realizes long-range economic benefit.
Core component in the smart well technology is permanent oil well sensing, and it is responsible for providing earthward the pressure and temp data.Along with the continuous exploitation in oil field, the degree of depth of Oil/gas Well constantly increases, and the operating ambient temperature of sensor is also more and more higher.The conditional electronic sensor has been difficult to satisfy the demand.According to foreign statistic, 18 ℃ of the every risings of downhole temperature, the fault rate of electronic sensor just improves 1 times.Royal Dutch Shell to the analysis showed that of 952 permanent oil well sensings of electronics, is being lower than under 100 ℃ the continuous operation environment between 1987-1998, and 12% sensor lost efficacy in 1 year, and 31% lost efficacy in 5 years.U.S. Quartzdyne company surpasses 450 high-temperature electronic sensors to it and tests under 180 ℃ of environment, surpasses 60% sensor failure in 3 months, and in 6 months, all sensors lost efficacy.Therefore, electronic sensor generally is used for being lower than 100 ℃ oil well.The temperature of some deep-sea oil wells has reached 200-250 ℃, and the temperature of thick oil filling gas well is up to 300 ℃.In these applied environments, electronic sensor can't meet the demands fully.
Optical fiber technology has all obtained application in a lot of fields, and this is because with respect to the mode of occupation of former electronic conductor, and optical fiber has a very large raising in that communication, the quality of reception and transmission speed are upper.At present in the application of Fibre Optical Sensor in the oil field with high temperature resistant, anticorrosive, anti-electromagnetic interference, use the advantages such as safety is not struck sparks, volume is little extensively to be approved, along with the development of oilfield exploitation technology, Fibre Optical Sensor will become a kind of trend in the utilization of oil field.Carry out at present oil well abroad and U.S. Weatherford company is arranged, U.S. Sabeus company, U.S. Baker-Hughs company with the company of Fibre Optical Sensor exploitation, Canada FISO company, Brazil Gavea company, Britain Sensornet company, French Schlumberger company.The main direction of the first five company is the single-point temperature and pressure transmitter, and the main direction of latter two company is distributed temperature sensor.
But the condition of oil field well is very harsh, and for example HTHP vibrates, corrosive fluid etc., and under the independent or common effect of these condition, Fibre Optical Sensor is easy to impaired, causes the in advance inefficacy of using at other field with respect to optical fiber.And be also noted that the impact that Fibre Optical Sensor is subject to easily in being installed to the process of down-hole, vibrate the impact of the factors such as friction.The working environment of down-hole all is disadvantageous for fiber plant in most of situation.Therefore in order to utilize the good technological value of optical fiber, need some can more effectively utilize optical fiber and can be with the more convenient solution that is placed in reliably the down-hole of Fibre Optical Sensor.
But, not yet have a kind of holder cylinder of extraordinary sensor to meet the following requirements simultaneously at present:
A: for sensor provides the installation site, reach the purpose that sensor is fixed at tubing string.
B: cable is pressed abd fixed on the holder cylinder, when cable is received extraneous pulling force, cable is extracted out in sensor, cause the interruption of sensor transmissions signal.
C: can provide Anti-bumping protection to sensor, extraneous impact be kept out by the holder cylinder, and sensor mounted thereto is not impacted.
