Pre-Production/Preparation

The volumetric coefficient is widely used in various calculations related to the estimation of petroleum reserves, crude oil production, preparation and transport of oil. The existing methods of its calculation determination are mainly empirical that makes it difficult to use them in solving various tasks, primarily optimization problems. The article is devoted to the development of similar technique in the form of analytical dependence, devoid of the noted shortcomings. For this purpose, the provisions of the hole theory of the dropping liquid are used, on the basis of which a theoretically and physically justified expression acceptable for a wide range of gas-saturated oils under different conditions is obtained. The acceptability of dependence is tested on oil data from different regions of the country and near abroad. The obtained dependence makes it possible to calculate the volume coefficient at a pressure equal to the pressure of oil saturation with gas.

The article analyzes the influence of errors from elastic deformations on the accuracy of processing in the conditions of complex automation. Different variants of multi-tool processing are considered: parallel processing, when different tools are alternately, one after the other, involved in the processing of the workpiece surfaces, and parallel-sequential processing, when different surfaces of the workpiece are processed simultaneously by several tools located in the working position. Design automation in machine-building production is part of the complex problem of automation of engineering work in all areas of the functioning of a modern production system. Therefore, when creating design automation systems, its connections in the general complex of automation of engineering activities in the production cycle should be taken into account. In general, the automation of the engineer's work is task planning, design and technological preparation of production, and management of the production system. The choice of favorable cutting modes for multi-tool processing is a difficult task, since, along with taking into account the features of each individual tool, it is necessary to make a general analysis of the entire setup, i.e. the set of tools used on the machine, and the distribution of processing transitions among them. Machine-building production is currently characterized by the desire to constantly update the range of released products. The requirements of multi-product manufacture can be met under the condition of its automation, which covers both the automation of production preparation and management. The article provides recommendations for reducing the error from elastic deformations in the conditions of complex automation.
