Description
Technical field:
The invention belongs to logger corollary apparatus field, be specifically related to a kind of a kind of lithology and density logging microsphere logging instrument coupling probe measuring density of earth formations and resistivity.
Background technology:
During oil well logging operation, different types of logger it is combined into instrument string operation in the wellbore.One of development trend of logger is that integrated, miniaturization is to shorten tool length.
At present, lithology and density logging probe and microsphere pole plate have the trend of integrated design, and unrealized real integration.General by following two scheme:
One is lithology and density logging probe and microsphere pole plate side assembled scheme, and they are together arranged on telescoping ram principal arm.Shortcoming is probe abutment face length, area increase, causing the probe patch borehole wall bad.
Two is lithology and density logging probe and microsphere pole plate side assembled scheme, is arranged on propeller auxiliary arm by microsphere pole plate, and shortcoming is that lithology and density logging is measured and Microsphere is not on same track (not at the same direction borehole wall), is unfavorable for log curve correlation analysis.And owing to lithology and density logging is popped one's head in well logging, microsphere pole plate all leans out, go into the well and easily meet card, cause well logging accident or damage microsphere pole plate, causing logging well unsuccessfully.
The most existing microsphere pole plate mostly is soft pole plate, and pole plate is wider than mounting seat, is easily damaged in logging operation.
Summary of the invention:
It is an object of the invention to the problems referred to above existed for prior art, a kind of lithology and density logging microsphere logging instrument coupling probe is provided, being installed on lithology and density logging and promote mainly on arm rest, pole plate is consistent with probe width and can realize lithology and density logging and microsphere well logging same track well logging simultaneously.
The object of the invention technical scheme:
A kind of lithology and density logging microsphere logging instrument coupling probe, including coupling probe housing, microsphere pole plate and coupling probe assembly, coupling probe assembly includes electronic circuit, crystal, photomultiplier tube, wherein: in coupling probe housing, be provided with axial cavity, coupling probe assembly is placed in axial cavity, the coupling probe hull outside corresponding with coupling probe assembly offers long rabbet, long rabbet was sealed by microsphere pole plate involutory connection, the axial cavity opening of coupling probe housing is connected sealing by sealed base, coupling probe housing is provided with source chamber and source window outside bottom, it is provided with inside coupling probe housing bottom and prevents leaning out protector, it is being respectively equipped with long space detection window and short space detection window near microsphere pole plate and the obverse upper and lower side of axial cavity.
Such scheme farther includes:
The electrode of microsphere pole plate is between long space detection window and short space detection window, and the upper and lower side of microsphere pole plate is sealed by pole plate respectively and microsphere signal connects seat and pressing plate is connected with coupling probe housing.
Described coupling probe housing axially has two different height, and two different height sections are chamfered transition, and install anti-abrading block additional at microsphere pole plate two ends.
Coupling probe housing upper end is connected with propeller auxiliary arm by probe galianconism, and the anti-probe protection cavity leaning out protector and be positioned on telescoping ram of coupling probe housing lower end and stopper limit and coordinate.
The technique effect of the present invention:
(1) due to the fact that the version of density and microsphere complete combination, microsphere pole plate are positioned at above density probe, be effectively increased the integration degree of instrument.
(2) microsphere of the present invention and lithology and density logging are popped one's head in integrated combination version, microsphere pole plate both sides width is consistent with density probe width, can draw in intracavity of popping one's head in completely, it is to avoid logging well is hampered, meets the well logging accidents such as card, improves success log ratio.
(3) microsphere pole plate of the present invention designs according to the geometry of the former probe of lithology and density logging, thus does not affect scale and the well logging of lithology and density logging.
(4) microsphere pole plate use hard electrode design, self with pole plate one pressure-bearing, sealing plug, lead-in wire installation, maintenance softer pole plate than microsphere, soft is more convenient, and reliability is higher.
Accompanying drawing illustrates:
Fig. 1 is a kind of lithology and density logging microsphere logging instrument coupling probe structural representation；
