Abstract
The utility model discloses an underground wireless LWD (logging while drilling) detection device. The underground wireless LWD detection device comprises a case mounted between drill rods, wherein a detection module and a sensor module are mounted in the case; and heat dissipating holes are formed in the case above the detection module. The underground wireless LWD detection module provided by the utility model has the advantages of simple structure, convenience in use, good heat dissipation effect, and long service life.
Description
Technical field
The utility model relates to a kind of oil drilling apparatus, is a kind of downhole wireless well logging during checkout gear concretely.
Background technology
At present, the well logging during checkout gear is generally with under the drilling rod lower going-into-well, because subsurface environment is abominable, affected by HTHP, affect application life, and the well logging during checkout gear in use can't dispel the heat, and, general design and installation together, like this when parts of damage, can only change fully, increase cost.
The utility model content
The purpose of this utility model is exactly the defective that exists for prior art, provides a kind of simple in structure, easy to use, good heat dissipation, the downhole wireless well logging during checkout gear that can increase the service life.
Its technical scheme is: downhole wireless well logging during checkout gear, comprise be used to the housing that is arranged between drilling rod, detection module and sensor assembly being installed in described housing, and be positioned at detection module top on described housing and be provided with heat elimination hole.
Described heat elimination hole is triangle or rhombus.
After having adopted technique scheme, the beneficial effect that the utility model is obtained is: the utility model is simple in structure, and is easy to use, and good heat dissipation has extended application life.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
As shown in Figure 1, downhole wireless well logging during checkout gear comprises be used to the housing 1 that is arranged between drilling rod, detection module 2 and sensor assembly 3 being installed in described housing 1, is positioned at detection module 2 tops on described housing 1 and is provided with heat elimination hole 4.
Described heat elimination hole 4 is triangle or rhombus.Certainly, also can be for rectangle etc., convenient heat radiation and be difficult for stopping up.
The heat that facilitates the interior checking module 2 of housing 1 and sensor assembly 3 to produce by heat elimination hole 4 dispels the heat, thereby extend the application life of detection module 2 and sensor assembly 3, when a certain damage of components, can change as required corresponding component gets final product, can increase the service life, applicable to the drilling rod of different size.
The utility model is simple in structure, and is easy to use, and good heat dissipation has extended application life.
Claims (2)
1. downhole wireless well logging during checkout gear, comprise be used to the housing that is arranged between drilling rod, detection module and sensor assembly being installed in described housing, it is characterized in that: be provided with heat elimination hole above being positioned at detection module on described housing.
2. downhole wireless well logging during checkout gear according to claim 1, it is characterized in that: described heat elimination hole is triangle or rhombus.
