Особенности строения природных резервуаров газового месторождения Западное Сулигэ
Аннотация
В статье предпринята попытка литолого-фациального анализа, проведенного по результатам геолого-геофизических исследований месторождения Западное Сулигэ, в целях уточнения пространственного размещения пород-коллекторов. Месторождение Сулигэ, расположенное в северо-западной части Ордосского нефтегазоносного бассейна, является одним из крупнейших и перспективных газовых месторождений Китайской Народной Республики.
В статье, в частности, рассмотрены особенности пространственного распределения палеорусловых песчаников. Исследование показало, что песчаники характеризуются унаследованным строением в направлении снизу вверх. Выявлено также, что песчаники вдоль направления сноса источников с севера на юг развиты шире, чем перпендикулярно, по направлению сноса с востока на запад. На основании данных геофизических исследований скважин, проведенных с применением самопроизвольной поляризации и гамма-методов, и построенных корреляций разреза были созданы трехмерные модели литологических фаций. Установлено, в частности, что нижний предел эффективности коллектора по пористости и проницаемости песчаника в исследуемом регионе составляет соответственно более 5 % и 0,06 мД, при этом газонасыщенность, как правило, превышает 50 %. Произведен подсчет запасов природного газа месторождения Западное Сулигэ с применением функции объемного расчета программы Petrel. Объем подсчитанных запасов природного газа категории С2 в районе исследования оценен в 1,0174·1012 м3.

Features of the Structure of Reservoir in the Western Sulige Gas Field
Abstract
The article attempts to lithologic-facies analysis based on the results of geological and geophysical studies of the Western Sulige field, in order to clarify the spatial distribution of reservoir rocks. The Sulige field, located in the north-western part of the Ordos oil and gas basin, is one of the largest and most promising gas fields in the People’s Republic of China. In particular, the article discusses the spatial distribution of paleochannel sandstones. The study showed that sandstones are characterized by an inherited structure from the bottom up. It was also revealed that sandstones along the direction of the drift of sources from north to south are developed more widely than perpendicularly – in the direction of drift from east to west. Based on the data of geophysical studies of wells conducted using spontaneous polarization and gamma methods, and constructed correlations of the section, 3D models of lithological facies were created. It was established, in particular, that the lower limit of reservoir efficiency for porosity and permeability of sandstone in the studied region is more than 5 % and 0.06 mD, respectively, while gas saturation, as a rule, exceeds 50 %. The natural gas reserves of the Western Sulige field were calculated using the volume calculation function of the Petrel program. The volume of reserves of natural gas of category C2 in the study area is estimated at 1.0174·1012 m3.
