中国陆上油气勘探已进入岩性地层油气藏与构造油气藏勘探并重的新阶段,大部分盆地的岩性地层油气藏已成为近年储量增长的主体.新近完成的资源评价结果表明,中国陆上岩性地层油藏占剩余资源的42%,在4个主要勘探领域中所占比例最高,是今后相当长一个时期内我国陆上最现实、最有潜力、最有普遍性的油气勘探领域.近几年,中油股份公司每年探明石油地质储量4.3×108t~4.6×108t,其中岩性地层油藏占50%以上,在松辽、鄂尔多斯、渤海湾、准噶尔、塔里木、四川、二连等盆地,新发现了安塞、靖安、大情子井、留西、石南21井区、哈得逊等一批地质储量5×107t~3×108t的岩性地层大油田.我国陆上四种类型盆地的岩性地层油气藏形成条件与分布规律各异,陆相盆地主要受不整合面、最大湖侵面和断裂面三个面控制,古生界海相盆地主要受古隆起、不整合和海平面升降控制.通过勘探实践和研究积累,中石油股份公司形成了以三维地震和层序地层学为关键技术的岩性地层油气藏勘探配套技术系列.
中國陸上油氣勘探已進入巖性地層油氣藏與構造油氣藏勘探併重的新階段,大部分盆地的巖性地層油氣藏已成為近年儲量增長的主體.新近完成的資源評價結果錶明,中國陸上巖性地層油藏佔剩餘資源的42%,在4箇主要勘探領域中所佔比例最高,是今後相噹長一箇時期內我國陸上最現實、最有潛力、最有普遍性的油氣勘探領域.近幾年,中油股份公司每年探明石油地質儲量4.3×108t~4.6×108t,其中巖性地層油藏佔50%以上,在鬆遼、鄂爾多斯、渤海灣、準噶爾、塔裏木、四川、二連等盆地,新髮現瞭安塞、靖安、大情子井、留西、石南21井區、哈得遜等一批地質儲量5×107t~3×108t的巖性地層大油田.我國陸上四種類型盆地的巖性地層油氣藏形成條件與分佈規律各異,陸相盆地主要受不整閤麵、最大湖侵麵和斷裂麵三箇麵控製,古生界海相盆地主要受古隆起、不整閤和海平麵升降控製.通過勘探實踐和研究積纍,中石油股份公司形成瞭以三維地震和層序地層學為關鍵技術的巖性地層油氣藏勘探配套技術繫列.

The onshore oil and gas exploration has stepped into a new stage in China, with equal attention paid to both stratigraphic and subtle reservoirs and structural reservoirs. In the past few years, the increases in oil reserves in most basins were found mainly in the stratigraphic and subtle reservoirs. Latest resource evaluation shows that the onshore stratigraphic and subtle reservoirs in China account for 42% of the total remaining resource, the highest in the four major exploration regions. Therefore, these reservoirs will be the most practical, potential and prevalent fields for long-lasting oil and gas exploration in onshore China. Among PetroChina's annual oil geologic reserves of 4.3×108t~4.6 × 108t, the stratigraphic and subtle reservoirs account for more than 50%. In such basins as Songliao, Ordos, Bohai Bay, Junggar, Tarim, Sichuan and Erlian basins, stratigraphic and subtle reservoirs with geologic reserves ranging from 5 × 107t to 3 × 10st were discovered,including Ansai, Jing'an, Daqingzijing, Liuxi, well-21 area in Shinan, and Hadexun. Stratigraphic and subtle reservoirs in the four types of inland basins differ from each other in the formation conditions and the distribution patterns. While continental basins are controlled by unconformity surface, maximum flooding surface and fracture surface, the Paleozoic marine basins are influenced by paleouplift, unconformity surface, and fluctuation of the sea level. Through exploration practices and research, PetroChina has formed its own technique series focused on 3-D seismics and sequence stratigraphy.
