Above-mentioned two kinds of cuttings are conducive to the differentiation of two cylindrical steel shells, are convenient to install, and can also indicate transmitting transducer/receiving transducer, the tram of sound insulation part below shell.
Described spacing pipe nipple assembly is constituted by the dismounting of the pipe nipple of acoustic isolater, centralizer, three kinds of different functions of flexible pipe nipple.
The major function of acoustic isolater is to isolate the shearing vibrations of vertical and horizontal, decay effectively and postpone harmful direct sound wave and disturb, being far to survey the pith that spacing is formed in the imaging of acoustic reflection ripple, is the pipe nipple that must have in emission sonic system and reception sonic system.
Flexible pipe nipple self can be on 360 ° circumferencial direction, can be arbitrarily crooked less angle, when the instrument string that has flexible pipe nipple removes in the process in the down-hole, when running into well direction flip-flop, can make the instrument string change direction thereupon bending, thereby the instrument string is passed through smoothly, prevent the instrument card that is hampered.
The main effect of centralizer is to make the instrument string placed in the middle, and the assurance instrument can be logged well between two parties.
This spacing can be regulated acoustic logging sonic system structure, can design the number range of spacing according to reflecting interface to the distance of the borehole wall and the calculated relationship of spacing when reality is logged well.According to spacing and borehole wall situation, select different numbers acoustic isolater, centralizer, flexible pipe nipple, be added in the emission sonic system and receive between the sonic system according to designing requirement, constitute the adjustable sonic system of spacing.This sonic system can be regulated spacing size and the order of connection according to actual needs at any time.Must be noted that in each pipe nipple that constitutes the variable source distance, will guarantee an acoustic isolater at least.
According to the time apart from the time curve map analysis of equation and different lithology as can be known, when the sonic system spacing is at least reflecting interface to 1.2-1.5 times of borehole wall distance, could observe back wave preferably.Spacing is too little or well external reflectance interface is too far away, and back wave appears at after the shear wave; Spacing is too big or the well outer boundary is too near, back wave easily and the follow-up ripple of compressional wave overlap, be unfavorable for signal extraction.The acoustic reflection ripple imaging logging instrument of surveying far away has carried out field trial in different kinds of rocks (as: tight sand, limestone, igneous rock, dolomite etc.).The short space that adopts during test is 3.85m, and long space is 13.1m.According to theoretical and on-the-spot well-log information analysis, spacing is chosen in the 8-13.71m scope, can measure the small-sized geological structure in the well week 3-10m scope.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
