Solid particle erosion of construction materials under the influence of hard abrasive particles is relevant to many elements of power equipment, gas and oil pipelines. Despite the large amount of experimental and theoretical studies, there is no sufficiently complete understanding of the dynamics of this process because of its statistical nature. The aim of this study was to research the influence of the gas-abrasive flow different attack angles on the erosive wear of flat X20Cr13 steel target. The studies found that with decreasing of gas-abrasive flow attack angle the depth of «the abrasive track» reduces, the length increases, and generally was marked increase in the area of the damaged area. Maximum of wear of flat X20Cr13 steel target observes at the gas - abrasive flow attack angle a close to 30 degrees. The results of these tests can be used for further researches of the solid particle erosion processes of steels used for the manufacture of power equipment, gas and oil pipelines.

The problem of maintaining oil production levels shouldn''t only be related to oil production intensification or increasing the reserves by geological exploration and new fields commissioning, but also due to the large-scale application of enhanced oil recovery. One of the well-known and relatively cheap to implement hydrodynamic methods of enhanced oil recovery technology is cyclic waterflooding. The technology consists of creating in a formation unsteady pressure differentials between layers and regions of different permeability via systemic change in well operating mode. The mechanism of enhanced oil recovery consists of water injection into stagnant oil-saturated low-permeability layers during increased water injection and displacing oil along with a part of the penetrated water into active drainage zones during reduced injection. Further development of cyclic waterflooding method involves the use of threedimensional hydrodynamic modeling for zones and regions selection and development of well operating strategy Based on multivariate three-dimensional hydrodynamic modeling of cyclic waterflooding for different oil field conditions a normalized criteria for the technology applicability is obtained. Map constructing algorithm to locate favorable areas and wells for the implementation of the technology is proposed.

On the example of the sedimentary section of the contact of the Paleozoic and Jurassic zone of Urmano-Archinskaya area the importance of lithogenetic step process identification is discussed for the forecast of high potential zone and of oil and gas prospects in general. Pre-Jurassicsedimentary interval of Archinskoye and Urmanskoe fields contains the supergene altered Paleozoic limestones altered by weathering and overlying redeposited laterites. The rocks have a complex composition; they are ambiguous in the genetic interpretation and prediction of reservoir properties. However, a wide range of oil and gas exploration and production problems - from hydrocarbon sources to forecast the quality of reservoirs, their irregularities and localization of traps is associated with this interval of the sedimentary section. On the basis of geological, geophysical data and detailed lithological characteristics the problems concerned to the lithogenesis of contact Paleozoic - Mesozoic zone as the basis of the forecast distribution and variability properties of the productive horizon are discussed.

The paper describes the problem of increasing the efficiency of the oilfield management by combining real-time information control systems for different purposes into a single network. To do this, the authors have developed a novel technology in order to organize such systems on the basis of the techniques of self-organization and adaptive interaction characterized by centralization of control functions and data processing, and provides the transition to dynamically changing network architecture. As the basis of the technology authors have proposed to apply a multiagent approach. Such an approach allows to produce systems, based on a wide variety of geographically distributed computational nodes of different performance, having direct communication with each other.
