ECOLOGY BUSINESS-ACCENT Of all operations in the oil and gas sector, operations related to well construction and servicing and auxiliary operations require greatest care and responsibility; and that is precisely why the Siberian Service company is committed to taking timely measures to avoid pollution and ensure efficient response to emergencies at production sites, progressively curbing the negative environmental footprint. The purpose of safety standards and regulations and of the upgrading of the Siberian Service company’s industrial manufacturing equipment are to ensure correct and safe implementation of all kinds of operations carried out. For example, when constructing Russia’s northernmost pipeline underwater passages over the Indikyakha and Muduyakha rivers at the East Messoyakha field, the rivers’ natural area was preserved undisturbed thanks to the Company’s decision to employ directional drilling technologies. And to eliminate the effect of heat on watercourses, the wallthickness of the pipeline passing under riverbeds is 30% higher. To avoid damaging the unique Arctic ecosystem, the pipeline was laid above ground using special technique for temperature stabilisation of permafrost soil. Site managers are personally liable for arrangement and control over the compliance with industrial safety provisions and relevant experts. The Siberian Service company’s management has set for itself the 0 target, i.e. maximum reduction of the accident rate, which is a goal that absolutely all of the Company’s employees are supposed to pursue. The Siberian Service company has a special labour and industrial safety and environmental monitoring department, which is consistently working to incentivise employees with regard to individual and collective security, timely adjustment of the internal security standards, as well as seeks to facilitate production modernisation as far as using safe operation schemes at complex facilities is concerned. The Company is committed to continuous work on improving its operations in terms of environmental and industrial safety, using stateof-the-art methods, processes and technologies, routinely upgrading personnel management, training and incentive systems. And one thing to be mentioned in this connection is a tradition that has caught on remarkably with the Company’s employees: every year the Siberian Service company celebrates the Day of Oil, Gas and Fuel Industry Workers by holding an FACTS 2 m from the ground is the height of the multi-ton objects for preservation of the unique soil and entire field infrastructure -60 °С air temperature in winter, lasting for 9 months in the Tazovsky Peninsula 70% of oil reserves is represented by heavy, high-viscose, resinous oil with a low content of light fractions 868 m area of fields discovered 2 6 mln tons of oil – production to be reached at the Eastern section in 2020 annual environmentalist volunteer community services day at all of its branches and offices. The Siberian Service company’s teams in Novy Urengoy, Moscow, Tomsk, Krasnoyarsk and Nefteyugansk lay out lanes, work on improving the land and the playgrounds, and plant trees and shrubs. “Our professional holiday is the day when all of us get an extra opportunity to dedicate a little bit more time than usual to sizing up our personal contribution to the development of one of Russia’s key industries,” said Vladimir Shesterikov, Siberian Service company CEO, speaking at one of the environmentalist events. “We are pleased to see that many Siberian Service company’s employees demonstrate tremendous solidarity coming out to work together at such events. By working alongside adults, children learn to be mindful of the environment, foster a responsible attitude to nature, keeping the place they live in both clean and comfortable”. Continual upgrading of technologies, expanding the Company’s presence, continuous retrofitting, social responsibility and environmental concern all constitute the Siberian Service company’s key competitive strengths. Siberian Service company is an independent Russian company offering a wide range of services to companies operating in the oil and gas sector. The Siberian Service company’s key business lines include prospecting, exploratory and production drilling of oil and gas wells, well servicing, engineering services related to directional drilling, development of drilling fluids and supervision of their use in production operations, and well cementing. The geography of the Company’s operations includes Western and Eastern Siberia, in the Volga region, and in the Far North. 76
SPECIAL SECTION Classifier ROLLING DRILLING TOOL 1.1 The equipment for oil and gas extracting 1.1.1 Drilling equipment and instruments 1.1.1.1.5 Drilling tools In drilling the wells the most widely used the rolling drilling bits. They performed yearly about 85% from the penetration volume in our country and abroad. On the operating principle it is breaking and shearing instrument. According to the design, rolling drilling bit is related to the mechanisms, as it has the rotation parts, positioned on the support bearing devices. The most popular is three-rolling drilling bit. The design of such bit allows the best way mechanism of the instrument to fit into the cylindrical well with three cone roller hits. At than it is ensured the appropriate centering and the constancy of performance the hit. Three rolling drilling bits are produced as sectional (without housing). Sectional three rolling drilling bit is made from the sections, welded together on all external loop of the contact surfaces. At that the upper segments of the sections for the connection head, on which the conical external thread is cut. The middle part makes a whole in the result of welding the shoes. On the external surface of the shoes, reaming lugs, beads and stiffening plates and round semi cylindrical nozzle boss are provided. Nozzles are fixed with the capture lock. The Sealing of the gapping between the nozzle and internal wall of the cavity is provided with the rubber sealing. Shirttail is usually protected with anti-abrasive coating. On the back of the roller hit the protection coating with good resistance to the abrasion of the calibrated surface, divided by one of the cone surface of the roller hit housing is overlaid. The tip of the first roller hit is made with the spade-shaped elements. On the upper butt end of the connection head the size, fabric number and frilling bit type, trade mark and batch number of the drilling bits is punched. Internal elements of the drilling bit The support of the roller hit is usually consists of the projecting central shaft, making a whole with the lug and bearings, allowing free rotation of the roller bit relating to the central shaft and transferring the axial and radial loads. One of the bearings simultaneously with the specified functions perform the role of the locking, fixing device, supporting the roller hit on the center shaft from the longitudinal displacement. So, such bearing is called locking. As a rule, it is made as ball bearing. Its balls are established in the corresponding hole through the cylindrical pass, drilled in the central shaft and locked after its installation with the special part, called locking plug. This part has a shape of the bar and performs the function of the plug, coming into the pass and not allowing the balls to roll out of the track.
