Abstract
The utility model relates to a high resolution factor acoustic wave well logging meter used for the earth physics well measuring in an oil exploration ore yard, which solves the problem of unable to measure the thin oil layer below 0.5 meter, characterized in that the inner chamber of a meter main body (11) is equipped with an acoustical insulation body (8) coated by a leather bag (7), the acoustical insulation body (8) is orderly sleeved with receiving probes (3, 4, 5. 6) and an ejecting probe (9), wherein the probes (3, 4, 5. 6, 9) all has spans, and silicon oil (10) is filled inside the leather bag (7). The utility model can identify the thin oil layer below0.5 meter. The spot operation is flexible and convenient, and a high resolution factor acoustic wave moveout curve and a common acoustic wave moveout curve can be extracted at the same time.
Description
The utility model relates to petroleum prospecting field geophysics logging instrumentation, belongs to the high resolving power acoustic logging instrument.
In the whole logging technology in oil field, acoustic logging occupies very consequence at present, and particularly in uncased hole, acoustic logging instrument is used for measuring the acoustic wave character of wellbore medium.Right that is in order to prolong the stable production period in oil field, and the off-balancesheet oil reservoir of exploitation below 0.5 meter is most important.For the oil reservoir below 0.5 meter, existing well logger can not be divided thin layer, can not provide reliable foundation for the exploitation of oil sheet, the estimation of oil reservoir reserves.
The purpose of this utility model is to avoid the weak point that exists in the above-mentioned present technology, and the high resolving power acoustic logging instrument of a kind of energy measurement oil sheet below 0.5 meter is provided.
The purpose of this utility model can reach by the following technical programs: this well logger is made of joint, transmitting probe and apparatus subject, it is characterized in that: the sound insulator that the apparatus subject inner chamber has leather bag to wrap up in mutually, and sound insulator is coated with 4 receiving transducers and 1 transmitting probe successively, wherein between the probe spacing is arranged all, filled with silicone oil is arranged in the leather bag.
The utility model has following advantage than above-mentioned prior art: because this well logger is made up of four receiving transducers and a transmitting probe, can pass through same measuring well section successively, obtain three high resolving power interval transit times, can discern the thin layer below 0.5 meter.
Accompanying drawing 1 is that structure of the present utility model is cutd open figure.
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, this well logger is made of joint 1, transmitting probe 9 and apparatus subject 11, the sound insulator 8 that apparatus subject 11 inner chambers have leather bag 7 to wrap up in mutually, there is silicone oil 10 to fill in the leather bag 7, damaged by pressure by pressure when avoiding going into the well, and sound insulator 8 is coated with four receiving transducers (3,4 successively, 5,6) and transmitting probe 9, make transmitting probe 9 and receiving transducer (3,4,5,6) spacing between is respectively 124.8CM, 109.2CM, 93.6CM, 78CM, and two-phase is faced receiving transducer (3,4,5,6) spacing is 15.6CM.During measurement, transmitting probe 9 is launched sound wave, and receiving transducer (3,4,5,6) converts acoustic signals to electric signal.Transmitting probe 9 emission four times is carried out complete documentation one time to four waveforms like this.
When four receiving transducers (3,4,5, when 6) passing through same measuring well section successively, can obtain three high resolving power interval transit times,, average again time difference addition, time difference value as this measuring section, relatively accurately, it is very little to utilize this time difference to calculate the average error of factor of porosity of factor of porosity and core analysis, can measure oil reservoir below 0.5 meter, be particularly suitable for 0.2 meter oil sheet Measurement and analysis, 0.1 meter oil sheet is had obvious reflection.Execute-in-place is flexible, can enroll high resolving power interval transit time curve and common interval transit time curve simultaneously.
