Abstract
The utility model discloses a bevel measuring device for followed drilling drill bit wells, which comprises a nonmagnetic drill collar. A followed drilling measuring unit is arranged in the nonmagnetic drill collar. A joint is arranged between the nonmagnetic drill collar and a screw. One end of the screw is arranged on the joint. A joint is arranged at the other end of the screw, and a drill bit is arranged on the joint. A near drill bit measuring unit is arranged on the joint. The near drill bit measuring unit comprises a well bevel measuring module. The utility model can accurately measure the current slope of the drill bit and primely control the quality of the well body of the drilling well by adopting the structure of the utility model.
Description
Technical field
The utility model relates to a kind of drilling equipment, especially relates to a kind of with boring nearly drill bit hole angle measurement mechanism.
Background technology
At present, along with skyrocketing and the high speed development of World Economics of oil price, people exploit without restraint to this non-renewable resources of oil, cause oil to visit reserves and reduce day by day, " oil sheet " oil that the past people do not consider worth doing to exploit always has to be subject to people's attention.We know will exploit this " oil sheet " oil, must be " horizontal orientation well ".Be that hole deviation is about 90 ℃ and need passes through certain distance in shallow oil reservoir.Because requirement in the horizontal orientation well drilling technology must add screw rod in drill bit and non magnetic drill collar (apparatus measures point), so just making between residing survey mark of instrument and the drill bit has certain distance.The data that instrument in non magnetic drill collar records at this moment can not reflect the situation of drill bit truly.According to the data that instrument records, think that mistakenly drill bit still creeps in oil reservoir, and actual drill bit may get out oil reservoir this moment, causes heavy economic losses.
Summary of the invention
The purpose of this utility model just is to provide a kind of measurement more accurately with boring nearly drill bit hole angle measurement mechanism.
The purpose of this utility model can realize by following measure:
The utility model comprises non magnetic drill collar, is provided with the measurement while drilling unit in non magnetic drill collar, is mounted with joint between non magnetic drill collar and screw rod, and an end of screw rod is placed on the joint, is mounted with joint at the screw rod other end, is mounted with drill bit on joint; Joint is provided with nearly drill bit measuring unit, includes the hole angle measurement module in the nearly drill bit measuring unit.
Screw rod in the utility model is at least one, two or three.Include acceleration transducer in the hole angle measurement module, acceleration transducer is directly to be placed on the joint.Also include wireless transmitter module in the nearly drill bit measuring unit; Comprise the wireless receiving module corresponding in the measurement while drilling unit with this wireless transmitter module.Between measurement while drilling unit and nearly drill bit measuring unit, be provided with holding wire.
The utility model can be measured the current inclination of drill bit exactly owing to adopt said structure, controls the wellbore quality of drilling well well.
Description of drawings
Accompanying drawing is a structural representation of the present utility model;
The specific embodiment
The utility model is done with detailed description below in conjunction with drawings and Examples:
As shown in the figure, the utility model comprises non magnetic drill collar (1), in non magnetic drill collar (1), be provided with measurement while drilling unit (2), between described non magnetic drill collar (1) and screw rod (4), be mounted with joint (3), one end of screw rod (4) is placed on the joint (3), be mounted with joint (5) at the screw rod other end, on joint (5), be mounted with drill bit (6); Joint (5) is provided with nearly drill bit measuring unit (7), includes the hole angle measurement module in the nearly drill bit measuring unit (7).Screw rod (4) is at least one or two or many.Include acceleration transducer in the hole angle measurement module, acceleration transducer is directly to be placed on the joint (5).In addition, some does not establish joint with boring in the nearly drill bit hole angle measurement mechanism between drill bit and screw rod, and at this moment, nearly drill bit measuring unit (7) is placed on screw rod or the drill bit.Also include wireless transmitter module in the nearly drill bit measuring unit (7); Comprise the wireless receiving module corresponding in the described measurement while drilling unit (2) with this wireless transmitter module.Be the wireless transmission working method this moment.Perhaps, between measurement while drilling unit (2) and nearly drill bit measuring unit (7), be provided with holding wire.At this moment, be the wire transmission working method.
Operating principle of the present utility model is as follows: the utility model as shown in the figure, the hole angle measurement module sends the bit inclination angular data that records to wireless transmitter module, wireless transmitter module is launched the data that obtain by form of electromagnetic wave; Wireless receiving module can receive these data, and wireless receiving module sends the data that receive to the measurement while drilling unit again.Like this, just obtained the real angle of slope of drill bit.。
The utility model installation site is at a distance of 1 meter of drill bit less than, and its measured angle of slope can be thought the angle of slope of drill bit substantially.
