Abstract
The utility model relates to a small-diameter noise logging instrument, which belongs to an annular noise logging instrument for an oil field. With the purpose of testing in a sleeve pipe and an oil pipe and annular testing, the logging instrument is designed, and is mainly composed of an outer cylinder 1, a power supply Inserter, a lining sleeve 3, a circuit board 4, a bracket 5, a sensor 6, an outer cylinder 7 of the sensor, an O-shaped sealing ring 8, a joint 9, etc., wherein, the outer cylinder 7 of the sensor is provided with a long bar-shaped window. The upper part of the sensor 6 is provided with the O-shaped sealing ring 8. The instrument is mainly used for annular testing noise, with the advantages of the improvement of instrumental sensitivity, the reduction of instrumental outside diameter, the widening of the range of application, etc.
Description
The utility model relates to the oilfield test technical field, belongs to annular space noise logging instrument.It can with magnetic localizer and the supporting use of temperature logging tool, be suitable for having the logging equipment of AT+ test macro.
BATS is at exploitation of oil field superencipher and the test of off-balancesheet reservoir exploitation, and three encryption development experiments middle sleeves are scurried increasing of groove phenomenon outward and developed.It can be scurried the groove position reliable foundation is provided for determining leakage.
The present domestic BATS that does not still have minor diameter.The BATS external diameter that oil fields such as grand celebration, Sichuan, the Liaohe River and Xi Yichang successively introduce is Φ 35-Φ 43mm.The weak point of these instruments is: can only test in sleeve pipe and oil pipe, can't test by annular space.
The purpose of this utility model is to avoid the weak point in the above-mentioned prior art and a kind of minor diameter fenestration noise logging instrument that can test by annular space of providing.
The utility model mainly is made up of urceolus, power insert, lining, circuit board, carriage, sensor, sensor urceolus, O RunddichtringO, joint etc.Wherein power insert is packed in the garden ring on carriage top, lining places between power insert and the carriage, plays insulating effect, and circuit board is fixed on the upper and lower side of carriage up and down with screw, the O RunddichtringO is equipped with on sensor top, seal, screwed connection in top and the carriage, rectangular window left by the sensor urceolus, make noise transducer exposed outside, especially responsive to noise signal, sensor urceolus upper end and carriage screwed connection, the lower end is connected with joint sealing with the O RunddichtringO by screw thread.
Sensor is made up of wire guide, main body, transducer, sound transmitting rubber, protective etc., and wherein main body top is the high pressure connection of two seal grooves, and the junction of main body and sound transmitting rubber is two seal grooves, and protective also is two seal grooves.
The utility model compared with prior art has following advantage:
1. this utility model adopts fenestration structure, the sensitivity that has improved instrument;
2. the reduced diameter of this utility model has solved the difficult problem of annular space noise testing, has widened the scope of application.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a minor diameter BATS structure diagram;
Fig. 2 is the sensor construction sketch.
The utility model is described in further detail below in conjunction with accompanying drawing:
The minor diameter BATS mainly is made up of urceolus 1, power insert 2, lining 3, circuit board 4, carriage 5, sensor 6, sensor urceolus 7, O RunddichtringO 8, joint 9 etc.Wherein sensor is made up of wire guide 10, main body 11, transducer 12, sound transmitting rubber 13, protective 14 etc.; main body 11 tops are for adopting the high pressure connection of two seal grooves; main body 11 is two seal grooves with the junction of sound transmitting rubber 13; sound transmitting rubber 13 closely bonds together with main body 11; guarantee to receive effectively the noise of downhole fluid like this, guarantee that also sensor 6 is under high pressure water-tight simultaneously.And protective 14 also adopts two seal grooves, further increased anti-high pressure ability.
During work, at first ground instrument is connected with cable one end, and places ground, upper end of the present utility model is connected with cable again, dress weighted lever in lower end in the lower going-into-well, and rests on institute's location with this instrument and puts.After sound in the downhole fluid is received by sensor 6, by transducer 12 transducings is that the signal of telecommunication is sent into circuit board 4 by the lead in the wire guide 10, after amplifying, the preposition amplification of process circuit board 4 and transmission send into cable, the duty of this instrument is determined by the supply voltage in the cable, when voltage during less than 45V this instrument do not work, instrument is operated in high gain state when voltage is 45-50V, and when voltage was 60V, instrument was operated under the low gain state.If the noise signal of the well of being surveyed is very big, then select the low gain state, if noise signal a little less than, then select high gain state.Signal carries out signal by circuit part to be handled, and finally delivers to ground instrument, the output measured result.
