Description

Novel pipe pole storage maintenance system for drilling/workover operation

Technical Field

The invention relates to a mechanical workover operation device in the petroleum industry, in particular to a novel pipe rod storage maintenance system for drilling/workover operation.

Background

The pumping well repairing operation is one operation measure that is necessary to be carried out in the development and production process of an oil field. At present, most oil fields are operated by using traditional equipment, at least two workers are required to convey and discharge the oil pumping pipe rod in a pulling and carrying mode, the working environment is severe, the labor intensity of the workers is high, and potential safety hazards exist in the operation process. Secondly, the oil pipe has crude oil drippage pollution in the transportation and storage process, and the method of preventing pollution in the traditional process is to spread a three-proof cloth on the ground of the whole workover operation to collect oil stain, and because the three-proof cloth has high manufacturing cost and can only be used once, high cost is caused. When the pipe rod is put into the well, 2-3 persons need to shut down the well for special measurement, the labor intensity of operation workers is increased, and errors are easy to generate during manual measurement and recording.

With the progress of society and the issuance of environmental protection laws, the more and more strict environmental protection requirements and operational specification requirements make it more and more difficult for the traditional operation mode to meet the new operational requirement standards. Semi-automatic workover pipe rod treatment systems are developed by petroleum machinery manufacturers in succession. In practical application, the design does not systematically consider the whole well repairing process and the environmental protection requirement, still needs manpower to discharge the pipe rods, and is not widely accepted.

The disadvantages of the conventional workover operations for oil wells are as follows:

1. the oil pipes are manually placed, so that the occupied area is large, the labor intensity is high, and the efficiency is low.

2. The polluted soil in the process of placing and transporting the oil pipes cannot be cleaned, and the requirements of green well site construction are not met.

3. Waste oil and waste water in the well repairing operation can not be comprehensively collected and discharged.

4. The number and the length of the pipe rods are counted, and the automation degree of pipe supplementing is low.

5. The existing operation mode needs a large amount of human resources and relates to the cooperation of multiple industries and types, and the average human cost is the best in the oil extraction industry.

Therefore, a need exists for a system for storing and maintaining a sucker rod during drilling/workover operations, which provides a convenient and efficient working platform for daily workover operations.
