Abstract
The utility model relates to a digital comprehensive automatic driller system, which includes a roller, a driller motor connected with the roller and a driller device connected with the driller motor. The driller device is connected with a control module for controlling the driller device and the control module is connected with an input device for selecting the control way. The control module is externally connected with a weight-suspension sensor, a pump pressure sensor and a roller coder installed on the roller. The system not only integrates mature constant drilling pressure control and constant drilling speed control, but also applies to constant pump pressure control for drilling level wells.
Description
Technical field
The utility model relates to the digital comprehensive automatic bit feed system that uses on a kind of petroleum drilling operation.
Background technology
Along with the continuous development of science and technology, the automatization level of petroleum drilling technology improves constantly, and automatic driller has become the basic configuration of modern drilling machine.But for the horizontal well that uses helicoid hydraulic motor, permanent the pressure of the drill automatic bit feed can not satisfy the needs of development.Horizontal well drilling technology is promoted at faster speed and is popularized in the world at present, becomes the important channel of improving oil field prospecting exploitation comprehensive benefit.The proportion of horizontal well in China oil field is also progressively rising.The automatic bit feed that creeps into based on permanent the pressure of the drill has been difficult to satisfy the control requirement for the horizontal well of working power drilling tool.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, and a kind of digital comprehensive automatic bit feed system is provided, to realize the permanent pump pressure control of permanent the pressure of the drill control, the control of permanent drilling speed and the horizontal well of fetching water.This system is applicable to various working, makes operating personnel easily according to actual condition, selects different control models.
For achieving the above object, the technical solution adopted in the utility model is: a kind of digital comprehensive automatic bit feed system, it comprises that cylinder, sending of being connected with cylinder bore motor and bore the drill feeding facility that motor is connected with sending, drill feeding facility is connected with the control module that is used to control drill feeding facility, described control module is connected with the input equipment that is used to select control mode, and described control module is circumscribed with the cylinder encoder of installing on weight transduser, pump pressure sensor and the cylinder.
The utility model compared with prior art has the following advantages:
(1) can improve application life of power drilling tool;
(2) can control the pressure of the drill, rate of penetration and permanent pump pressure control function;
(3) has the pressure reduction control function of power drilling tool motor;
(4) have the pressure of the drill amplitude limit function, motor maximum pressure drop amplitude limit function;
(5) reduce driller's labour intensity, the generation that improves wellbore quality, minimizing down-hole accident and reduction drilling cost.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
The specific embodiment
As shown in Figure 1, the digital comprehensive automatic bit feed system of the utility model, it comprises that cylinder 5, sending of being connected with cylinder 5 bore motor 4 and bore the drill feeding facility 3 that motor 4 is connected with sending, drill feeding facility 3 is connected with the control module 2 that is used to control drill feeding facility 3, described control module 2 is connected with the input equipment 1 that is used to select control mode, and described control module 2 is circumscribed with weight transduser 7, pump pressure sensor 8 and is installed in cylinder encoder 6 on the cylinder 5.
Beating the peupendicular hole stage, can adopt permanent the pressure of the drill control or the control of permanent drilling speed according to actual condition.Permanent the pressure of the drill control and the control of permanent drilling speed are by weight transduser 7, cylinder encoder 6, control module 2, drill feeding facility 3, the closed-loop control system of sending brill motor 4 and cylinder 5 to constitute.The pressure of the drill or drilling speed are maintained in the certain numerical value scope, with protection drilling equipment and raising drilling efficiency.
When fetching water horizontal well, can adopt by the working power drilling tool permanent pump pressure control.When operation, need the operator to import some parameters of the power drilling tool of current use: motor maximum pressure drop, work pump pressure, maximum the pressure of the drill, these parameters are used for calculating motor pressure reduction amplitude limit and the pressure of the drill amplitude limit respectively.When being in permanent pump pressure duty, pump pressure sensor 8 sends detected pump pressure signal and weight transduser 7 detected suspending weight signals to control module 2, control module calculates by the control corresponding algorithm and sends drill feeding facility 3 controls behind the result to and send and bore motor 4, drag cylinder 5 and change its rotating speed, realize permanent pump pressure control.
It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the spirit and scope of technical solutions of the utility model.
