Description
Technical Field

Background
The screw pump for oil extraction is one kind of single screw type hydraulic machinery and is one application of cycloid inner meshing spiral gear pair. The rotor and stator pair (also called screw-bush pair) of screw pump utilizes cycloidal multiple equivalent dynamic point effect to form closed cavity in space, and when the rotor and stator are relatively rotated, the closed cavity can be axially moved, so that the liquid in the closed cavity can be moved from one end to another end, and the mutual conversion of mechanical energy and liquid energy can be implemented, so that the lifting action can be implemented. It has the advantages of both centrifugal pump and volumetric pump. The screw pump has few moving parts, no valve body and complex flow passage, good suction performance, small hydraulic loss, continuous and uniform suction and discharge of medium, difficult sedimentation of sand grains, no fear of abrasion, difficult wax deposition and no generation of airlock because of no valve. Therefore, the screw pump has become a practical and effective mechanical oil extraction device.
At present, the screw pump oil extraction technology mainly focuses on the aspects of improvement of a ground driving device, screw pump rod column anti-reversion technology, ground protection technology and the like, and few researches on the fault judgment of a screw pump well are limited. Such as: (1) and judging the fault by a current method. The method is a method for judging the state of the underground rod column of the screw pump well by using the measured current of the motor. But the running current is lower when the depth under the screw pump is shallower. When the oil well does not output liquid, the rod column is not loaded, the current display is lower, and the current is close to the no-load current of the motor of the screw pump driving device, so that the rod column can not be judged to be broken and separated, the sinking degree of the pump is not enough, or the liquid supply of the oil well is not enough. (2) And (5) judging the fault by a pressure building method. The fault judgment cannot judge whether the rod column is normal, the underground screw pump is normal, the pipe column is normal and the like when the submergence degree of the screw pump is shallow. Therefore, no effective judgment method is available at present for accurately judging the fault type of the screw pump well.

As shown in fig. 3, the present embodiment provides a method for determining a fault type of a screw pump well, including the following steps:

Therefore, when the screw pump is stopped, the entire string is connected to the polished rod and suspended in the entire string. And the load of the polished rod is measured, so that whether the pipe column is in good condition or not can be known.
In some embodiments, load data and torque data for a screw pump well string may be obtained according to the following methods:

Specifically, the sensor power line and the data line can be connected to one end of the rod string close to the wellhead through the hollow part of the hollow rod string, and a connecting contact is arranged. Accordingly, the connection contacts may include power contacts and data contacts. During the normal working period of the screw pump well, the sensor is in an open circuit and is not electrified.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate a dedicated integrated circuit chip 2. Furthermore, nowadays, instead of manually making an integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (Hardware Description Language), and vhigh-Language, which are currently used in most popular applications. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
From the above description of the embodiments, it is clear to those skilled in the art that the present specification can be implemented by software plus a necessary general hardware platform. Based on such understanding, the technical solutions of the present specification may be essentially or partially implemented in the form of software products, which may be stored in a storage medium, such as ROM/RAM, magnetic disk, optical disk, etc., and include instructions for causing a computer device (which may be a personal computer, a server, or a network device, etc.) to execute the methods described in the embodiments or some parts of the embodiments of the present specification.
The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, for the system embodiment, since it is substantially similar to the method embodiment, the description is simple, and for the relevant points, reference may be made to the partial description of the method embodiment.
The description is operational with numerous general purpose or special purpose computing system environments or configurations. For example: personal computers, server computers, hand-held or portable devices, tablet-type devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments that include any of the above systems or devices, and the like.
This description may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. The specification may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices.
While the specification has been described with examples, those skilled in the art will appreciate that there are numerous variations and permutations of the specification that do not depart from the spirit of the specification, and it is intended that the appended claims include such variations and modifications that do not depart from the spirit of the specification.
