One of the main sources of obtaining information about the degree of heating of the oil reservoir and the effectiveness of steam cyclic treatment of wells is geophysical research, which consists in measuring the temperature in the wellbore using a descent geophysical instrument.
This is a rather laborious and not always successful process. As an alternative, this article attempts to develop an engineering software product capable of predicting the temperature distribution in a well and thus partially or completely replace the downhole survey. The neural network underlying the engineering product was trained on data from the wells of the Usinskoye field. The article notes that forecasting the temperature distribution in wells can allow engineers to find and implement the most rational modes of steam cycling treatment.

Materials and methods
When designing, generating, testing neural networks and neural network modeling, software tools, developments and experience of the scientific school of the Perm State National Research University were used. To train neural networks, a dataset was used, created on the basis of steam cycling data from 50 wells in the Usinskoye field.

Problem solving for emergency early detection at gas-main multi-pipeline linear part by linear telemechanics systems

Sergey V. Yevseyev


The present work object is to add the telemechanics system by methods for detecting gas-main multi-pipeline points of leakage. There are proposed algorithms for detecting gas pressure decrease at the sensor arising at the beginning of the leak and updating mathematical map of gas-main multi-pipeline (GMMP). Analysis of dispatcher actions when eliminating real breakdown in case of gas-pipeline partial break at the boundary of two linear production areas (LPA) was carried out. As a result of the analysis there is proposed a solution for accurate defining the point of leakage within LPA at the basis of providing additional communication channel between the end supervised stations.

Materials and methods
The work presents the algorithm for detecting pressure decrease at telemechanics supervised stations, the method for generating an integrated information card of gas-main multi-pipeline, an example of the real breakdown is studied and a conclusion was drawn about the necessity of interaction between the adjacent sections of the gas-main pipeline.

Problem of defining leakage at multi line gas-main pipeline by standard linear telemetering gear

Sergey V. Yevseyev

The present work objective is to define the main reasons causing complexity of defining leakage location at a multi-line gas-pipeline by a shift dispatching personnel on the basis of the information received from the linear telemechanics system. Analysis of dispatcher actions in case of real breakdown elimination when the gas-pipeline is broken completely was carried out. As a result of the analysis there are indicated available telemechanics systems basic shortcomings and the ways to solve the said problems. An important aspect presented in the work is the necessity of using system approach to the information recorded by the linear telemechanics system and creating additional methods and algorithms for automated processing this information in order to define the time and location of the emerged leakage without specialized sensors.

Usually the infrastructure of oil producing companies is distributed geographically and has distant objects. Data transmittion from all objects to control point can bring to problems related to the lack of system performance. This paper considersthe issue of the regime of sporadic transmission.
