To construct a mathematical model of this process, the soil is represented as a solid body with a system of vertical cylindrical microtubules with the same diameter, and the infiltration of liquid into the soil is represented as the movement of a cylindrical liquid layer of variable height formed in the microtubule. It is assumed that liquid slides on the microtubule wall is according to Navier's law. First, formulas are proposed for determining the forces of inertia and viscous friction on the microtubule. Taking into account the acting forces, a mathematical model of the motion of a cylindrical liquid layer in a microtubule is constructed, which is a nonlinear ordinary differential equation of the second order. The resulting model is represented as a system of nonlinear ordinary differential equations of the first order with initial conditions. A discrete analogue of the latter problem is constructed using the finite difference method and a computational algorithm is proposed for the numerical solution of the resulting nonlinear system of difference equations. Numerical experiments were carried out on the basis of the proposed computational algorithm. Keywords: infiltration of oil and petroleum products into the soil; the model of ideal soil; sliding according to Navier's law; the finite difference method.","PeriodicalId":43516,"journal":{"name":"SOCAR Proceedings","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87841090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on laboratory studies, it has been found out that from one ton of water, on average, 180–210 kg of well killing fluid and 140–150 kg of common salt can be obtained, and dilution of heavy brine with fresh technical water can significantly increase the cement stone strength when fixing wells. The carried out simulation tests indicate that there is no deterioration in the reservoir properties of productive formations when they come into contact with heavy brines and the possibility of using such brines as a well killing fluid.

Technological processes and a set of equipment created using the supersonic movement of natural gas are studied, their advantages and disadvantages are analyzed. It is known that a change in the process of gas injection into UGS facilities in a wide range of pressure during the season creates opportunities for more efficient use of compressor equipment. The thermobaric parameters of gas cooling due to supersonic motion in various designs have been calculated, and the existence of ample opportunities for creating new technological processes has been proved. Recommendations have been developed on the throughput capacity of gas installations to ensure the regulation of cooling systems created for underground gas storage facilities. It was noted that the cooling and gas separation systems created on the basis of thermobaric parameters and principles of regulation will be useful not only for underground gas storages, but also for other sub-sectors of the gas industry.

The article considers: conventional megareservoirs of oil and gas bearing basins (OGB), in which giant and unique oil and gas deposits are accumulated (on the example of the Pokur suite of Western Siberia); megareservoirs associated with commercial vanadium-bearing heavy oils and natural bitumen in unconventional reservoirs: bituminous sands in the province of Alberta (Western Canadian OGB), Permian natural bitumen in the Volga-Ural (Republic of Tatarstan) OGB, Cambrian bitumen in Eastern Siberia; megareservoirs of unconventional low-pore shale reservoirs. These accumulations of hydrocarbons (HC) can be considered megareservoirs: due to their vast areas and high saturation with kerogen. It is shown that accumulations of hydrocarbons in megareservoirs of shale formations, high-viscosity oils and natural bitumens accumulate ore concentrations of industrially valuable metals; an integrated approach to field development is economically in demand in the present conditions.

It is noted that large-scale oil and gas accumulation is possible in natural reservoirs that meet certain conditions. Reservoirs with good characteristics, in the presence of a powerful source of replenishment of hydrocarbons, can form larger deposits with sufficient trap volumes in the natural reservoir. With a homogeneous reservoir with high characteristics, the distribution area of hydrocarbon accumulation can be more concentrated. Heterogeneous reservoirs more often generate hydrocarbon accumulations scattered over the area. Using the example of unique and large deposits in the junction zone of the Yenisei- Khatanga regional trough with the West Siberian depression, a dependence with a high correlation coefficient between the value of hydrocarbon deposits and the effective volume of the trap, which is determined by the effective thickness of the reservoir and the area of distribution of the trap in the natural reservoir, was obtained. In the area of the Vankorskoye , Tagulskoye and Vostochno-Messoyakhskoye fields, the collectors of the Yakovlevskaya and Nizhnekhetskaya formations with the highest oil and gas saturation have the maximum effective capacity and distribution area.
