gravimetry

Steel corrosion processes that occur due to the effects of the biochemically treated water in coke quenching plenums have been studied. Model investigations into the processes of the corrosion failure of carbon St. 3 steel and alloyed 18Х1MF  steel were carried out to study the behavior of the  metal exposed to the action of the primary but treated water used for the coke quenching after the metal is heated to 373 K and 773 K.

The introduction of elements of geographic information technologies in the process of interpretation of gravity anomalies led to the possibility of constructing three-dimensional density models every detail of the earth's crust. These models meet the criteria of Hadamard. The results obtained allowed to identify new and confirm the previously known patterns.

In connection with ambiguity of the decision of return problems of gravimetry (RPG) very sharply there is a question on existence of absorption of a gravitational field (GF) by a substance. For definition of various factors as measures of absorption of a field some variants of direct problems of gravimetry (DPG) for sphere are solved.

Mathematical formulations of specific geophysical problems are usually reduced to determination of coefficients in the equations of mathematical physics, comprising a formulation. In the groove of the fact, the solution of the Alexidze problem in the form of non-linear integral equation has been reduced to linear combination of desired solutions. Then, the resulting problem was reduced to a classical problem of variational calculation.

Purpose. Identify patterns in position earthquake hypocenters relative density stratification in the borders of the earth's crust. Methods. The methods of the new interpretative gravity anomalies by interpreting the gravity field is determined by the power of the earth's crust, forming the anomaly in the gravity field (Bouguer). In this border area forms a surface that separates two sector of the earth's crust. In its upper part, in the sector above the fixed surface, observed density change substance at the transition from one block to another in the horizontal direction.

In the absence of a priori information about the geological structure of study area the structural nonlinear inverse problem (IP) is incorrect and its solution is ambiguous and even physically nonsense or difficult to interpretation. Therefore it is possible to use a space-fixed multilayered model of linear IP with horizontal strata which are composed of quite a large number of blocks in the boxes form (400 to 2500) and to solve the linear IP relative to anomalous density (AD) or the intensity of magnetization (IM) of each block.

A new area is suggested for hydrocarbon explorations in the margin shaft of the Eurasian platform, in the Transcarpathians. The productive systems: Devonian, Carboniferous, Jurassic, Cretaceous, Paleogene, Neogene. Traps of various types are possible.

The goal. The UQG2012 regional quasigeoid solution of an accuracy better than 4 cm with respect to the GPS-levelling data of the 1st and 2nd order was constructed by means of the least squares collocation method. In the first iteration the gravimetry-only quasigeoid UQG2011 was developed from the gravity anomalies for the subsequent detection of gross errors in GPS-leveling data. All terrain reductions were based on the 3x3 digital terrain model SRTM3. Scientific significance.
