Abstract

The issues of improving the efficiency of processing the results of studying the reservoir filtration properties (RFP) within the oil-and gas-producing areas of the central part of the West Siberian petroleum province are considered. The high degree of development of the hydrocarbon resources of the studied area is determined by the presence of deposits that developed for a long period of time. It enables one to solve tasks aimed at increasing the efficiency of searching for complex deeply buried reservoirs, as well as the efficiency of their exploration and additional exploration, since the overlying productive horizons are practically developed. This task is considered one of the most important at the current stage of field development in this region due to the decline in oil production at the main large fields and is open to interpretation. The present paper covers the issues of reservoir modeling using new scientific and methodological approaches to geophysical data processing and the possibility of using modern software products when grouping development objects according to criteria corresponding to a reservoir of a certain lithotype. This approach allowed us to develop high-quality geological models and justify the use of the most effective complex of geophysical studies for modeling low-amplitude (no more than 15 m) and small(less than 20 km²) oil deposits. In the course of research the results of studying the reservoir filtration properties were processed; low-amplitude and small deposits of channel sediments (river valleys) were established, the commercial oil and gas content of complex sediments characterized by low-amplitude and small deposits (Tyumen Formation, Yu₂ reservoir) was proved, the results of geophysical exploration (GIS) in wells were interpreted, the GIS results were compared with the energy characteristics of the reflected waves (seismic studies), zones saturated with water-oil-gas fluids were established (3D models were developed), and the possibility of using this technique for identifying and mapping complex deep oil deposits was shown.

在模拟复杂石油储量时提高处理储层过滤研究和参数结果的效率

摘要

研究了西西伯利亚石油省中部油气产区储层过滤特性（RFP）研究结果的提高处理效率问题。研究区油气资源的高度开发是由长期发育的矿床的存在决定的。它使人们能够解决旨在提高寻找复杂深埋储层的效率的任务，以及它们的勘探和额外勘探的效率，因为实际上开发了上覆的生产层位。由于主要大油田的石油产量下降，这项任务被认为是该地区现阶段油田开发中最重要的任务之一，并有待解释。本论文涵盖了使用地球物理数据处理的新科学和方法论方法进行储层建模的问题，以及在根据与特定岩型储层相对应的标准对开发对象进行分组时使用现代软件产品的可能性。这种方法使我们能够开发高质量的地质模型，并证明使用最有效的复杂地球物理研究来模拟低幅度（不超过 15 m）和小型（小于 20 km）是合理的²）油藏。在研究过程中，对研究储层过滤特性的结果进行了处理；_{建立了河道沉积物（河谷）低幅度小沉积，证实了以低幅度小沉积为特征的复杂沉积物（秋明组、豫2}储层）的商业油气含量，物探成果（解释井中的 GIS），将 GIS 结果与反射波的能量特征进行比较（地震研究），建立水-油气-流体饱和区（开发 3D 模型），以及使用该技术的可能性用于识别和绘制复杂的深层油藏。
