Для того чтобы открыть (обнаружить)

Для того чтобы открыть (обнаружить) нефтяное и газовое месторождение необходимо выполнить целый комплекс поисково-разведочных работ, который включает в себя несколько этапов: полевые, геологические работы, поверхностные геофизические и геохимические исследования, бурение разведочных скважин с одновременными глубинными исследованиями.
Основная задача первого этапа разведки - выполнить геологическую съемку - метод изучения поверхностной геологии и геоморфологии местности, на основании чего составляется геологическая карта района. На этом этапе изучают выходящие на дневную поверхность элементы пластов и образцы горных пород, окаменевшие остатки древних животных и растений, измеряют углы и направление простирания (падения) пластов, вы¬полняют необходимые лабораторные анализы.
Для более детальной структурной геологической съемки бурят мелкие картировочные и структурные скважины глубиной от 20 до 300 м, которыми «проходят» все наносные современные отложения и достигают коренных пород, устанавливая структуру их и отбирая пробы коренных пород для описания и последующего лабораторного изучения.
По результатам первого этапа работ строят геологическую карту района, на которой условными обозначениями отражают распространение пород различного возраста.
Более детально геология района описывается дополнительно предполагаемым сводным стратиграфическим разрезом в виде колонки с последовательно изображенными по глубине породами и структурной картой, отражающей поверхность характерного пласта и форму его распространения.
На втором этапе используют поверхностные геофизические, геохимические и биологические методы разведки, позволяющие косвенно установить вероятное местонахождение нефтегазового пласта.

To unlock (find) oil and gas field you must complete a range of exploration, which includes several stages: field, geological works, surface geophysical and geochemical studies, drilling of exploratory wells with simultaneous profound research.The main objective of the first phase of exploration-run geological survey-learning method of surface geology and geomorphology of the area, which is a geological map of the area. At this stage of the study on the surface elements and samples of rocks, the fossilized remains of ancient animals and plants, measure the angles and direction reach (fall) layers, you will perform the necessary laboratory tests.For more detailed structural geological survey bore small kartirovočnye and structural wells from 20 up to 300 m, which "are" all the modern sediments of silt and reach bedrock, establishing the structure of it and taking samples of the bedrock for description and subsequent laboratory analysis.Based on the results of the first phase of building a geological map of the area on which the symbols reflect the distribution of rocks of different ages.The geology of the area is described in more detail further the alleged composite stratigraphic section in the form of columns with consistently depicted in depth and structural map reflecting surface typical of the formation and shape of its distribution.In the second phase use surface geophysical, geochemical and biological methods of exploration, to indirectly set the probable location of oil and gas reservoir.

To discover (detect) oil and gas fields must perform a complex exploration, which includes several stages: field, geological work, surface geophysical and geochemical studies, drilling of exploratory wells with simultaneous depth of investigation.
The main objective of the first phase Intelligence - perform geological survey - method for studying the surface geology and geomorphology of the area, which is made ​​on the basis of the geological map of the area. At this stage, exploring emerging to the surface layers and elements of rock samples, fossils of ancient animals and plants, measured angles and direction of stretch (fall) formations vy¬polnyayut necessary laboratory tests.
For a more detailed structural geological survey is drilled small Kartirovochno and structural wells with depths ranging from 20 to 300 m, which "pass" all modern alluvial sediments and reach the bedrock, establishing their structure and taking samples of bedrock for the description and subsequent laboratory study.
As a result of the first phase of building a geological map of the area in which the symbols reflect the distribution of rocks of different ages.
A more detailed geology area is described further alleged summary stratigraphic column in the form of a sequence of images with depth rocks and structural maps showing the surface characteristic of the formation and shape of its distribution.
In the second stage using surface geophysical, geochemical and biological intelligence allowing indirectly establish probable location of oil and gas reservoir.

In order to open the (discover) oil and gas should be to perform a set of prospecting and exploration activities, which includes a number of stages: field, geological work,Surface geophysical and geochemical studies, drilling exploration wells with simultaneous underlying research.
The main task of the first stage of exploration is to perform geological surveys - method to investigate surface geology and geomorphology terrain, on what grounds is geological map of the area.At this stage the day exploring beyond the surface elements reservoirs and sample rocks, petrified remnants of ancient animals and plants, measure the angles and direction at (fall) reservoirs,You¬complement the necessary laboratory analyzes.
For more detailed structural geological survey are drilled small картировочные and structural drilling depth 20 to 300 m,The "pass" all discussed this frankly modern sediments and reach indigenous species, installing the structure of their samples and robbing indigenous species for the description and subsequent laboratory study.
On the results of the first phase of work build geological map of the area, in which symbols reflect the distribution of species of different ages.
A more detailed geology the area is described further alleged consolidated due cut in the form of a column with consistently portrayed in depth native species and structural map,Distinctive reflective surface reservoirs and its form of disseminating.
in the second stage using surface geophysical, geochemical, and biological methods of prospecting,To help indirectly to establish probable location gas reservoir.
