Исследование газообразных углеводородов донных отложений - основа, на которой построена геохимическа методика поисков нефт ных и газовых месторожений в водных бассейнах , разрабатываема в насто щее врем в СССР и других странах.The study of gaseous hydrocarbon deposits in bottom sediments is the basis on which the geochemical method for searching oil and gas deposits in water basins, which is currently being developed in the USSR and other countries, has been developed.
Известный способ отбора и обработки донных геохимических проб заключаетс в том, что подн та со дна колонка донных отложений извлекаетс пегерметичными грунтовыми трубками, разрезаетс на определенные части, отделенные образцы помеплаютс в стекл нную посуду, герметизируютс крышкой, затем дегазируютс специальным дегазатором, и отобранные газы анализируютс . При этом донные отложени соприкасаютс с атмосферным воздухом, в результате происходит естественна дегазаци и потер газов. Результаты анализов газов, даже на весьма чувствительных хроматографах, не отражают естественного состава газообразных соединений, а данные по компонентам нос т качественный, нежели количественный характер. Таким образом , известный способ извлечени газов вл етс весьма несовершенным. По полученным данным трудно судить о составе газов и использовать их при геохимических поисках залежей нефти и газа.A known method for the selection and processing of bottom geochemical samples is that the bottom sediment column is removed from the bottom by pegging soil pipes, cut into certain parts, the separated samples are heated into glassware, sealed with a lid, then degassed with a special degassing agent, and the selected gases are analyzed . At the same time, bottom sediments come into contact with atmospheric air, as a result of which natural degassing and gas losses occur. The results of gas analyzes, even on highly sensitive chromatographs, do not reflect the natural composition of gaseous compounds, and the data on the components are qualitative rather than quantitative. Thus, the known method of gas extraction is very imperfect. According to the data obtained, it is difficult to judge the composition of gases and to use them in geochemical searches for oil and gas deposits.
Целью изобретени вл етс новышение достоверности геохимических исследований и их удешевление.The aim of the invention is to increase the reliability of geochemical studies and reduce their costs.
Сущность изобретени состоит в том, что донные отложени поднимают специальным устройством в герметизированные секции, в каждой из которых имеетс отверстие. Свободный газ принудительно извлекаетс через отверсти и подаетс на анализ. Дл извлечени сорбированного газа кажда секци подогреваетс и аналогичным образо.м газ извлекаетс из донных отложений и подаетс в газоанализатор . Таким образом получают характеристику как свободного, так и сорбированного газа (без искажени результатов за счет контакта донных отложений с воздухом). Предложенный способ значительно дешевлеThe essence of the invention is that bottom sediments are lifted by a special device into sealed sections, in each of which there is an opening. The free gas is forcibly removed through the orifices and fed to the analysis. To extract the sorbed gas, each section is heated and, in a similar manner, the gas is extracted from the bottom sediments and fed to a gas analyzer. Thus, a characteristic of both free and sorbed gas is obtained (without distorting the results due to the contact of bottom sediments with air). The proposed method is much cheaper
известного, так как сокращаетс количество операций, а следовательно, средств и трудозатрат на его реализацию. Кроме того, этот способ позвол ет получить достоверные результаты и повысить эффективность геохимическихknown, as the number of operations and, consequently, the cost and labor costs of its implementation is reduced. In addition, this method allows to obtain reliable results and increase the efficiency of geochemical

Предмет изобретени Subject invention
Способ отбора и обработки донных геохимических проб, заключающийс в извлечении, дегазации и десорбции сорбированного газа в донных отложени х, отличающийс тем, что, с повышени достоверности результатов исследовани и их удещевлени , отбор грунта производ т с помощью герметизирующего устройства, свободный газ извлекают из 3 грунта принудительно без контакта с атмосферными газами, десорбцию сорбированного газа производ т путем термической обработки 4 грунта непосредственно в пробоотборнике, а освобожденный таким образом газ извлекают также принудительно.The method of sampling and processing of bottom geochemical samples, which consists in extracting, degassing and desorbing sorbed gas in bottom sediments, characterized in that, with increasing the reliability of the research results and their reduction, the selection of soil is carried out using a sealing device, 3 the soil is forced without contact with atmospheric gases, desorption of the sorbed gas is performed by heat treatment of 4 soils directly in the sampler, and the gas thus released is extracted Cabins are also mandatory.
