Abstract
The utility model discloses a combined logger with hydrogen sulfide resistance. The combined logger comprises a cable head, a rotary short joint, a measuring device formed by an built-in circuit, a sensor and a metal shell, a stabilizer and a sampler, wherein the measuring device orderly comprises remote metering and positioning gamma combined device, a temperature and pressure combined device, an X-Y caliper device, an online flow metering device, a water holding capacity device and a full hole flow metering device; and the above devices are all in a threaded connection with the metal shell. The combined logger with hydrogen sulfide resistance can be combined according to construction needs, thereby meeting requirements for different measuring parameters of an oil and gas well.
Description
Technical field
The utility model relates to a kind of combination well detecting Instrument, is specifically related to a kind of anti-H 2 S combination logging tool.
Background technology
At present, Oil/gas Well output adopts single flow meter to measure mostly, adopt typical turbine flow meter in oil pipe and sleeve pipe, to measure, but it is high to start discharge capacity, the measurement of inapplicable stripper well simultaneously; The startup discharge capacity of full bore flowmeter is low, but full bore flowmeter can only be surveyed the flow velocity in sleeve pipe, cannot measure the flow velocity in oil pipe.These two kinds of flow meters can not be crossed line because of structure and can only be connected on instrument string bottom, thereby cannot descend together well measurements, and turbine is positioned at the lower end of instrument, and in actual use, turbine is easily stuck, causes flow measurement to do over again, and wastes time and energy; The sealing ring of simultaneous logging instrument generally adopts fluorubber material, and in high-hydrogen sulfide environment, the inefficacy of can expanding very soon of fluorubber material, loses sealability, so this logging instrument is not suitable for the measurement of high-hydrogen sulfide environment oil, gas well.
Utility model content
The purpose of this utility model is to provide a kind of anti-H 2 S combination logging tool that can meet Oil/gas Well different measuring parameter needs.
For achieving the above object, the utility model is by the following technical solutions:
Anti-H 2 S combination logging tool, comprise measuring instrument, centralizer, sampler that cable head, rotating short-knot, built-in circuit and sensor and metal shell form, described measuring instrument comprises remote measurement magnetic orientation gamma combination instrument, temperature, pressure combination instrument, XYC, online flow meter, water holdup tool, the full bore flowmeter being threaded with described metal shell successively.
Described metal shell is threaded connection and is formed by outer tube and connecting short section, the metal C shape sealing ring of resistance to hydrogen sulfide is installed between the end face that described outer tube is combined with connecting short section, the O RunddichtringO of resistance to hydrogen sulfide is installed in the screw thread joint portion of outer tube and connecting short section.
Anti-H 2 S combination logging tool of the present utility model comprises cable head, rotating short-knot, measuring instrument, centralizer, sampler; Remote measurement magnetic orientation gamma combination instrument, temperature, pressure combination instrument, XYC, online flow meter, water holdup tool, full bore flowmeter that measuring instrument comprises built-in circuit, metal shell and is threaded with metal shell successively, this anti-H 2 S combination logging tool can need to carry out applied in any combination according to construction, can meet the needs of Oil/gas Well different measuring parameter.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the utility model;
Fig. 2 is the generalized section of metal shell.
The specific embodiment
?embodiment of the present utility model, as shown in Figure 1-2: anti-H 2 S combination logging tool comprises measuring instrument, centralizer 4, the sampler 9 that cable head 1, rotating short-knot 2, built-in circuit and sensor and metal shell form.Metal shell is threaded and is formed by outer tube 14, connecting short section 11, the metal C shape sealing ring 12 of resistance to hydrogen sulfide is installed between the end face of outer tube 14 and connecting short section 11 combinations, the O RunddichtringO 13 of resistance to hydrogen sulfide is installed in the screw thread joint portion of outer tube and connecting short section.Measuring instrument comprises remote measurement magnetic orientation gamma combination instrument 3, temperature, pressure combination instrument 5, XYC 6, online flow meter 7, water holdup tool 8, the full bore flowmeter 10 being threaded with metal shell successively.
During work, cable head 1 is connected with logging cable, is that anti-H 2 S combination logging tool is powered, and receives the data that downhole instrument is uploaded by cable; The torsion that rotating short-knot 2 can be applied to cable instrument discharges, and prevents the dropout of instrument screw thread; Centralizer 4 carries out righting in conjunction with XYC 6 and 10 pairs of whole string instruments of full bore flowmeter below, has improved the accuracy of measuring, and has prevented the wearing and tearing between instrument and sleeve pipe; Remote measurement magnetic orientation gamma combination instrument 3 can be measured collar and stratum gamma, and is responsible for the data of all parameters in down-hole to be sent to ground simultaneously; The temperature and pressure value that temperature, pressure combination instrument 5 is responsible under measuring well; XYC 6 is responsible for measuring hole diameter; The rate of flow of fluid that online flow meter 7 can be measured in oil pipe can be measured the flow velocity of fluid in sleeve pipe again, and can articulate Other Instruments below; Water holdup tool 8 is responsible for measuring the specific retention of downhole fluid; 9 pairs of down-hole liquids of sampler sample; Full bore flowmeter 10 carries out the measurement of the flow of interval of interest, and the turbine area of this anti-H 2 S combination logging tool is large, starts discharge capacity low, and flow-speed measurement is accurate.
External metallization component of the present utility model and sealing ring all adopt the materials processing of hydrogen sulfide corrosion resistant to form, be applicable to the measurement of high-hydrogen sulfide well, instrument is once gone into the well and can be recorded collar, gamma ray intensity, temperature, pressure, tubing string internal diameter, specific retention, eight curves of seven parameters of flow simultaneously, flow is wherein included in linear flow rate and two curves of full hole flow, greatly improved the success rate of flow measurement, and can sample down-hole liquid.
