Abstract
The utility model discloses a double trust force combined well logging meter of lithology density and micro-ball for oil well logging, which comprises a trust spring(1), a spring lead rod(2), a micro-ball polar plate(3), a frame(4), a polar plate frame(5), a propeller main body(6) and a lithology density detector(7). The propeller main body(6) is connected with the lithology density detector(7), and one side of the propeller main body(6) is provided with the micro-ball polar plate(3); the polar plate frame(5) is provided with the micro-ball polar plate(3), and one end of the micro-ball polar plate(3) is connected with the spring lead rod(2); the frame(4) is arranged at the micro-ball polar plate(3). The utility model uses the lithology density detector instead of the compensation density detector for well logging, and is provided with the structure of integrated well logging meter; as using the lithology density detector instead of the density detector, when detesting the well, the lithology density detector is combined with the micro-ball polar plate and both are arranged at the same propeller, which produces different thrust force to the well wall.
Description
Technical field
The utility model provides a kind of logging instrument that LDS replaces the well logging of compensation density probe of using, specifically, be that a kind of double applying leans on power lithology and density logging-microballoon combination logging tool, it relates to the mechanical part of density quasi-instrument and electrical method instrument combining structure.
Background technology
For remedying the technical deficiency of compensation density probe in the formation at target locations well logging, satisfy the demand of " integrated well logging " operation simultaneously, in the structure of the highly integrated combination of instrument string, the instrument of band backup satisfies the synchronous well logging of density and layer resistivity (or microballoon etc.) as much as possible.The scheme that addresses this problem at present has two kinds: a kind of is that resistivity (or microballoon) pole plate is attached on the compensation density probe, realizes the combination logging of two kinds of instruments.Another kind is that resistivity (or microballoon) pole plate is installed on the auxiliary (the compensation density probe back side) of compensation density (hydraulic pressure backup).
First kind of scheme is bigger to the density log influence.Second kind of scheme is comparatively serious to the wearing and tearing of resistivity (or microballoon) pole plate.
Summary of the invention
The purpose of this utility model is to provide a kind of double applying by power lithology and density logging-microballoon combination logging tool, it replaces the well logging of compensation density probe with LDS, and possess " integrated well logging " apparatus structure, substitute density detector with LDS; LDS and microballoon pole plate are installed on the same telescoping ram when combination logging, produce different from the borehole wall power that reclines.
Technical solutions of the utility model are as follows: comprise thrust spring 1, spring guide 2, microballoon pole plate 3, carriage 4, pole plate frame 5, telescoping ram main body 6, LDS 7, telescoping ram main body 6 is connected with LDS 7, side in telescoping ram main body 6 is equipped with microballoon pole plate 3, settle microballoon pole plate 3 on the pole plate frame 5, one end of microballoon pole plate 3 is connected with spring guide 2, and microballoon pole plate 3 is provided with carriage 4.
Replace the well logging of compensation density probe with LDS, and possess " integrated well logging " apparatus structure, substitute density detector with LDS; LDS and microballoon pole plate are installed on the same telescoping ram when combination logging, produce different from the borehole wall power that reclines.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in drawings, comprise thrust spring 1, spring guide 2, microballoon pole plate 3, carriage 4, pole plate frame 5, telescoping ram main body 6, LDS 7, telescoping ram main body 6 is connected with LDS 7, side in telescoping ram main body 6 is equipped with microballoon pole plate 3, settle microballoon pole plate 3 on the pole plate frame 5, one end of microballoon pole plate 3 is connected with spring guide 2, and microballoon pole plate 3 is provided with carriage 4.
The augmented thrust part that design is formed with pole plate frame 5, carriage 4, thrust spring 1, spring guide 2 on microballoon pole plate 3 supports, when telescoping ram main body 1 was opened work, its upper end guaranteed the power that reclines of 7 couples of about 50Kg of the borehole wall of LDS; The same backup power (50Kg) of microballoon pole plate 3 carrying on telescoping ram main body 6 back side backup auxiliarys, the i.e. borehole wall that microballoon pole plate 3 is produced about 20Kg by the augmented thrust on the pole plate frame 5 power that reclines.The reaction (50Kg) of pole plate frame 5 carrying LDSs 7, the borehole wall that carriage 4, thrust spring 1 and 2 pairs of microballoon pole plates of spring guide 3 the produce about 20Kg power that reclines.
Because LDS 7 and microballoon pole plate 3 be under the well logging duty, the active force of the borehole wall that reclines is required difference, when development " integrated logger ", densilog instrument is respectively two different instruments that respectively carry telescoping ram with microsphere logging instrument.When instrument group string, the length of instrument string is longer, can not satisfy the job requirements of " integrated well logging ".Realize the combination logging of " integrated logger " string, the technology of this part becomes solution and shortens " integrated logger " string length, the key of problems such as lifting density log technical level.
Finish the logging operation of two kinds of probes simultaneously by a telescoping ram.The on-the-spot actual tests of process produces a desired effect, thereby has promoted the technical level of density log, has solved the key technical problem of " integrated logger " effectively.
