Abstract Many ways of information about the downhole pressures of existing wells collecting have long been outdated. With the improvement of processing techniques, the need to modernize the ways of information about oil and gas fields obtaining becomes more obvious. Many oil and gas industries are developing in this direction. The article discusses an innovative technology for downhole characteristics monitoring, which is called multi-well deconvolution. It is based on the creation of a system of equations that includes the relationship between the downhole pressure and the flow rate graph. This technique has been widely used among foreign research groups, but it was not until recently that it started to be applied in the Russian Federation. The first oil and gas companies to be interested in the multi-well deconvolution technology were Gazpromneft and Rosneft, which managed to conduct some studies using thу technology and confirmed its profitability. This technology makes it possible to assess the well operation mode and predict its further operation, which in turn makes it possible to optimize the development and operation modes.

Drill Collar

Casing wear is one of the key issues in the development of oil and gas fields and in the process of drilling operations. In this study, the relationship between hardness and wear resistance of drill collar and casing was studied; thereby the wear conditions between the two materials were improved. Chemical analysis, optical microscopy, hardness test and friction wear test were conducted to study the effects of heat treatment on hardness of the drill collar 4145H and the casing 30Mn5V, and discuss the relationship between hardness and wear resistance of them. The results showed that the materials of drill collar and casing after different heat treatment had varying degrees of wear, both of the respective wear amounts were gradually increasing with the increase of hardness of them, the wear extent of casing material was greater than that of drill collar material. The hardness of casing material was the lowest and its wear resistance was the best when quenching at 880°C and tempering at 630°C. And when quenching at 900°C and tempering at 690°C, the hardness of drill collar material was the lowest and its wear resistance was the best. Therefore, the hardness of drill collar and casing can be improved by changing the heat treatment process to improve the wear resistance, thereby reducing the wear conditions between them.
