Abstract
The utility model relates to an integrated combination logging instrument capable of realizing measuring various downhole data, which is composed of a data transmission gamma ray logging instrument, a density logging instrument, a sound wave logging instrument, centralizers and a connection interface. The upper portion of the integrated combination logging instrument is equipped with a standard interface, the lower portion of the standard interface is sequentially connected with the data transmission gamma ray logging instrument, the density logging instrument and the sound wave logging instrument. The upper portion and the lower portion of the integrated combination logging instrument are provided with the centralizers. Signals of each of the data transmission gamma ray logging instrument, the density logging instrument and the sound wave logging instrument can be transmitted to a ground receiving system though respective plug sockets by communication cables. The integrated combination logging instrument capable of realizing measuring various downhole data has the advantages of replacing multiple single clogging instruments to measure downhole data, shortening the instrument overall length and the spreading distance of data cables, integrally measuring downhole data, improving working efficiency, and obtaining various data at one time.
Description
Technical field
The utility model relates to a kind of logger, particularly a kind of integrated combination logging tool of realizing multiple underground data measuring.
Background technology
In the prior art, the measurement of oil field downhole data, all adopt single logger to obtain required data, required instrument quantity is many, and measuring number of times increases, data are inaccurate, the explanation of stratigraphic structure is needed the data support of a plurality of instruments, and data are loaded down with trivial details, and labour intensity is big, production efficiency is low, has increased the input of cost of production.
Summary of the invention
The purpose of this utility model provides a kind of integrated combination logging tool, this logging instrument can replace the measurement of many single logging instruments to downhole data, shortened the propagation distance of the contour length and the data cable of instrument, downhole data has been realized integrated measurement, improved operating efficiency, once can obtain several data by this instrument.
The utility model is achieved through the following technical solutions:
Integrated combination logging tool, this device is made of number biography gamma ray logger, densilog instrument, acoustic logging instrument, centralizer, connecting interface, the device top interface that sets up standard, the standard interface bottom is connected with number in turn and passes gamma ray logger, densilog instrument and acoustic logging instrument, and the device upper and lower is provided with centralizer; The signals transmission that number passes gamma ray logger, densilog instrument and the acoustic logging instruments all socket by separately transfers to ground receiving system by communication cable.
The beneficial effects of the utility model are: this logging instrument can replace the measurement of many single logging instruments to downhole data, shortened the propagation distance of the contour length and the data cable of instrument, downhole data has been realized integrated measurement, improved operating efficiency, once can obtain several data by this instrument.
Description of drawings
Fig. 1 is the structural representation of integrated combination logging tool.
The specific embodiment
See Fig. 1, integrated combination logging tool, this device is made of number biography gamma ray logger 3, densilog instrument 4, acoustic logging instrument 5, centralizer 2, connecting interface 6, the device top interface 1 that sets up standard, standard interface 1 bottom is connected with number by connecting interface 6 and passes gamma ray logger 3, number passes gamma ray logger 3 bottoms by connecting interface Connection Density logging instrument 4, and densilog instrument 4 bottoms connect acoustic logging instrument 5 by connecting interface; The device upper and lower is provided with centralizer 2; The signals transmission that number passes gamma ray logger 3, densilog instrument 4 and the acoustic logging instruments 5 all socket by separately is connected to ground receiving system by communication cable and transmits.
The utility model will be counted and pass gamma ray logger 3, acoustic logging instrument 5, densilog instrument 4 and do to mutually combine in frame for movement and signal transmission, shortened the overall length of instrument, shorten to 30.7 meters by 40.6 meters, the module of electronic circuit has been carried out integrated, simplify the structure, cancelled the centralizer quantity that every list props up instrument, be reduced to 2 by 6.Combination logging tool can be obtained following data simultaneously by once going into the well: the 1) intensity of cementing, the degree of porosity of cement, the firm intensity of the gluing of sleeve pipe and cement, and the identification of lithosphere character; 2) determine the size of rock behavio(u)r and drilling well hole diameter; 3) determine clay component, identification igneous rock, identification radioactive element.
Each instrument connecting interface all adopts 5700 standard interfaces, can with conventional supporting connection of 5700 instruments, the transmission of the signal of each instrument interconnects the receiving system that is transferred to ground by communication cable by the socket that connects.Every flat spring thrust of centralizer is about 10kg, guarantees that effectively the instrument string is centered at the well head center; The borehole wall that the probe backup arm of density produces about 50kg by the driven by motor power that reclines can guarantee tight contact the under pole plate and the borehole wall are in working order, the accuracy of raising data.
Every index of device is as follows:
The length overall of instrument string is 30.7 meters;
Withstand voltage: 140MPa;
Heatproof: 150 ℃;
Impact resistance: 50g 11ms;
Operating voltage: 250vac/50-60Hz;
Measurement category: bulk density 1.0-3.0g/cm3; Photoelectricity index 1.0-14Pe unit;
Pole plate opens power: 〉=45kg;
Pole plate opens the time :≤2s,
Certainty of measurement: URAN-uranium ± 1.5ppm, POTA-potassium: ± 0.1%; 131 μ s/m≤T≤200 μ s/m
Integrated combination logging tool can be obtained several data by one action, through on-the-spot actual tests, has reached the effect of design, has improved the order of accuarcy and the operating efficiency of data, has reduced job costs, has solved the difficult problem of integrated well logging.
