Abstract

The stadial structure of the formation of technogeosystems of oil and gas fields (TGSOGF) are characterized based on field and laboratory studies using remote sensing data from 12 key study plots within oil and gas fields in the Volga–Ural steppe region. TGSOGF is understood as a complete set of modified natural components and technological facilities that function as a whole during the development of an oil and gas field. Two main principles of the formation and functioning of a TGSOGF are distinguished. The first principle implies the temporal stadiality of development, determined by the period of field development and by the level (variety) of technogenic load on the landscape. The other principle is the reversible and irreversible transformation of landscape components, leading to changes in mutual physical-energy connections of its vertical and horizontal structures. The random diffuse-linear distribution of structural links of oil and gas fields forms a specific space of technogenic influence, which is characterized by the overlap, intersection, and combination of impact zones of oil and gas production facilities. There are five stages of transformation of the initial landscape with varying degrees of involvement of components in the transformation process. The initial landscape structure is formed from a technogenic block, including units with the irreversible introduction of structures of liquidated and/or temporarily abandoned wells at the final stage of field development. This results in the manifestation of equifinality: the completion of the oil and gas production process becomes equivalent for different landscapes and the natural invariant is replaced by the natural-technogenic one. Analysis of the features of oil and gas fields and determination of patterns of their functioning gave rise to the proposed concept of formation of a TGSOGF and made it possible to rationalize the optimization of the environmental management of oil and gas fields, taking into account the systematic principles of TGSOGF development and stadiality.

油气田技术系统地层特征及作用原理

摘要

油气田技术地质系统 (TGSOGF) 地层结构的特征基于现场和实验室研究,使用来自伏尔加 - 乌拉尔草原地区油气田内 12 个关键研究区的遥感数据。TGSOGF被理解为在油气田开发过程中作为一个整体发挥作用的一套完整的改性天然成分和技术设施。TGSOGF 的形成和功能的两个主要原则是有区别的。第一个原则意味着发展的时间稳定性,由田地开发的时期和景观上的技术负荷水平(种类)决定。另一个原则是景观成分的可逆和不可逆变换,导致其垂直和水平结构的相互物理能量连接发生变化。油气田构造联系的随机扩散-线性分布形成了一个特定的技术影响空间,其特点是油气生产设施影响带的重叠、交叉和组合。初始景观的转变有五个阶段,其中组件在转变过程中的参与程度不同。最初的景观结构由技术区块形成,包括在油田开发的最后阶段不可逆转地引入已清算和/或暂时废弃的井结构的单元。这导致等价性的表现:石油和天然气生产过程的完成对于不同的景观变得等效,自然不变性被自然技术成因取代。对油气田特征的分析和对其功能模式的确定,提出了形成 TGSOGF 的概念,并使油气田环境管理的优化合理化成为可能,同时考虑到系统性TGSOGF 发展和稳定性的原则。
