Abstract
The utility model relates to a shell structure for installing a near-bit well deflection measuring pup joint of a vertical well drilling tool. The shell structure is mainly used for solving the problem that the deflection measuring sensors in the existing vertical well drilling systems cannot be placed at the centers of shells and is characterized in that two grooves are axially arranged on a nipple body (1) and are respectively used for placing a well deflection measuring pup joint (7) and a circuit board (11); the two grooves are communicated with each other through a threading hole (9); the outer part of the well deflection measuring pup joint (7) is fixed on the pup joint body (1) through a buckling cover (6); and the circuit board (11) is fixed on the pup joint body (1) through a circuit board buckling cover (10). By adopting a split type, the shell structure for installing the near-bit well deflection measuring pup joint of the vertical well drilling tool is convenient for mounting and dismounting and is capable of meeting the mounting of near-bit survey instruments.
Description
Technical field
The utility model relates to the field, oil field, and a kind of specifically vertical drilling tool is installed the shell structure of nearly drill bit directional survey pipe nipple.
Background technology
Measurement-while-drilling system or logging system all dispose the deviational survey sensor at present, and its effect is a hole deviation parameter of measuring well, carry out well track in view of the above and calculate and control.General directional survey sensor all adopts the form of inserting tube to place housing central authorities; But in the vertical drilling system because the requirement of close-in measurement is arranged; And the restriction that receives other machineries and physical space, can not be placed on housing central authorities, therefore can't realize the installation of nearly drill bit measuring apparatus.
Summary of the invention
In order to overcome the problem that deviational survey sensor in the existing vertical drilling system can't be placed on housing central authorities; The utility model provides a kind of vertical drilling tool that the shell structure of nearly drill bit directional survey pipe nipple is installed; The shell structure that this vertical drilling tool is installed nearly drill bit directional survey pipe nipple adopts split type; The installation of nearly drill bit measuring apparatus has been satisfied in easy installation and removal again.
The technical scheme of the utility model is: a kind of vertical drilling tool is installed the shell structure of nearly drill bit directional survey pipe nipple; Comprise pipe nipple body, directional survey pipe nipple; Axially have two grooves on the described pipe nipple body, place directional survey pipe nipple and circuit board respectively, be communicated with by cable-through hole between two above-mentioned grooves; Described directional survey pipe nipple outside is fixed on the pipe nipple body through buckle closure, and described circuit board is fixed on the pipe nipple body through the circuit board buckle closure.
Described directional survey pipe nipple passes through screw on the pipe nipple body, and connects through holding wire between directional survey pipe nipple and the circuit board.
The utlity model has following beneficial effect: owing to take such scheme; This pipe nipple adopts split-type structural; Directional survey pipe nipple and circuit board are placed on enclosure interior; Both avoided taking the space of housing central authorities, the installation that has solved nearly drill bit measuring apparatus again, and easy installation and removal, sealing are reliable.

The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
By Fig. 1, shown in Figure 2, a kind of vertical drilling tool is installed the shell structure of nearly drill bit directional survey pipe nipple, comprises pipe nipple body 1, directional survey pipe nipple 7; Axially have two grooves on the described pipe nipple body 1; One of them cross section is to place directional survey pipe nipple 7 in the semicircular groove, and another cross section is the interior circuit board 11 of placing of the groove of rectangle, is communicated with by cable-through hole 9 between two above-mentioned grooves; There is holding wire to pass in the cable-through hole 9; Connect directional survey pipe nipple 7 and circuit board 11 through holding wire, described directional survey pipe nipple 7 is fixed on the pipe nipple body 1 through screw 5, and directional survey pipe nipple 7 outsides are provided with buckle closure 6; The position that buckle closure 6 contacts with pipe nipple body 1 is provided with O type circle 4, with the enhanced leaktightness effect.Described buckle closure 6 is fixed on the pipe nipple body 1 through trip bolt 2; And trip bolt 2 outsides are fixing by circlip 3; Described circuit board 11 is fixed on the pipe nipple body 1 through circuit board buckle closure 10; Described buckle closure 6 and circuit board buckle closure 10 external surfaces and pipe nipple body 1 external surface match, and the right side of described pipe nipple body 1 is provided with the annular groove of placing conduction communication link 8.
The shell structure that this vertical drilling tool is installed nearly drill bit directional survey pipe nipple adopts split-type structural, easy installation and removal, and housing seal is reliable, and resistance to compression reaches 70MPa; Directional survey pipe nipple 7 is placed on enclosure interior, avoids taking the space of housing central authorities, realized that in limited space nearly drill bit measures the installation of pipe nipple instrument components and parts, and overall construction intensity, resistance to shock are high, satisfy the abominable operating mode in down-hole.
