What should be checked for on-site inspection of drilling equipment?

The day-to-day inspection of the well-drilling equipment for protection on the ground should be conducted, starting with a determination of vehicle traffic, stationation of equipment and support for the suspension. With regard to the construction of drilling platforms, the relocation of equipment, the supply of materials and the auxiliary hang-up sites, the topic is concerned with what “the daily inspection of surface protection of drilling equipment should look at” which usually follows multiple stages of entry, construction, overhaul and evacuation, and changes in ground water content and traffic. The most vulnerable to neglect is the lack of support on the edge of the road, which leads to the bending and crushing of the sheet. The problem of grass-roots and drainage may have expanded if only ad hoc slabs were added after a vehicle has been trapped.

The technical communication should first identify the control design of the driller module, the transport vehicle axial load, the tracked size, the retroactivity of the crane leg, the equipment set-up, the underground facility, the site endurance and the conditions of the rainy season. It is proposed to set speed limits, prohibit in-situ wheeling and arrange for exclusive command for heavy vehicles, and to require suppliers to specify the materials for the pavement or stubble, the finished goods, the methods of testing, the basis of application and the conditions of limitation. Reference data such as nominal 50 to 200 tonnes cannot be directly compared horizontally without the same test basis. With regard to “what should be checked for routine ground protection inspections of drilling equipment”, the information review should also check the continuity of lighting, reflective boundaries and night-time transfer records and include missing information as items to be confirmed for quotations and construction programmes.

A smooth transition should be put in place at the different ground crossings to avoid the sudden impact of vehicles on temporary circuits from hard roads. The internal and external wheels and brake positions of the most heavy vehicles will also be reviewed after the installation of a speed limit, a ban on in-situ wheeling and a exclusive command for heavy vehicles has been completed. The rigs shall distinguish between vehicle access, stationing of equipment and cranes, and the pavement shall be responsible for the protection of the ground and the mats shall be accounted for on the basis of maximum reversibility and durability. Physical segregation and clear rules for release are required in the vicinity of public areas. The trial preparation record of “what should be checked during the day-to-day inspection of the protection of the well-drilling equipment” should indicate the starting and ending position, vehicle condition and release conclusions, so as to facilitate review as construction conditions change.

The inspection should not only be “normal”, but should be identified around the track track, the permanent deformation of the sheet, the deposition of the legs, the drainage of the floor, soft spots, connectors, mud contamination and the level of the level, and the anomalies should be classified into three stages: observation, restriction and decommissioning. A fixed photo angle and measurement benchmark should be established for key points that are designed to set speed limits, prohibit in situ wheeling and place a person in command for heavy vehicles. A loose connection, a permanent deformation, a breach through or a deviation of a branch shall be immediately isolated. What should be checked during the daily inspection around “ground protection of drilling equipment”, the inspection forms are to show a lack of support on the edges of the separate road, leading to changes in the bending and crushing of the sheet, as well as a reference to the repeater and the time of return.

The offers from different suppliers should be compared under the same size, material, connection, packaging, delivery and test basis. Supplementation should be requested if the maximum load is given without a description of the ground, distance and load. The oil and gas project should also focus on batch consistency, removal efficiency, repairability and container loading. It should also answer whether “the day-to-day inspection of the protection of the well-drilled equipment on the ground should examine” has been certified as improved by setting speed limits, prohibiting in situ cycling and arranging for exclusive command of heavy vehicles, avoiding a subjective description of the conclusion.

The construction, equipment, HSE and logistics team should confirm the use of the same version of data before the procurement is issued. The common dimensions, thickness or reference load range referred to in this paper are not on-site commitments and actual performance is influenced by materials, temperature, foundations, connections and installation patterns, and the recommended results should indicate assumptions and no application.

The following special checks should also be carried out in connection with the construction of drilling platforms, the relocation of equipment, the supply of materials and the auxiliary suspension site: the daily inspection forms should be itemized by location, not just normal. It is recommended that the photo angles be fixed, comparing downfalls, faults, loose connections, swipes and pollution changes, and that those responsible be identified, processing times, the results of the re-examination and the conditions for reopening.

On-site implementation of recommendations: The frequency of inspections should be adjusted to traffic and weather changes. The duration of the stabilization period can only be increased appropriately, with additional checks after laying, heavy rainfall, after heavy vehicle concentrations and during night shifts, and a spot-check mechanism is maintained.
