摘要:
为突破制约柴达木盆地油气勘探的瓶颈,“十三五”以来,在“向非常规进军、向深部找油气”的思想指导下,大力推进了非常规和深部油气的勘探和理论研究工作。经过几年的攻关研究,取得了一系列新进展和新认识:明确了咸化湖相烃源岩母质类型及生烃机理,建立了可溶有机质、干酪根和矿物质相互作用而显著提高产烃率的“三元”成烃模式;总结了细粒碳酸盐岩、深层碎屑岩和基岩储集层特征及成储机制;建立了混积碳酸盐岩油藏和深层碎屑岩气藏成藏模式。在理论认识的指导下,落实了英雄岭构造带深层混积碳酸盐岩油藏、冷北斜坡带深层碎屑岩气藏、阿尔金山前基岩气藏等一批勘探目标,并获重大发现。截至2019年4月,累计新增油气探明三级地质储量2.5×108 t原油当量。
Abstract:
Since the 13th Five-Year Plan, in accordance with the guiding ideology of “marching toward unconventional oil and gas and prospecting oil and gas in deep strata”, the Qinghai oilfield has vigorously promoted the exploration of unconventional and deep oil and gas resources and the studies on related theories. Over several years of research, a series of new progresses and new understandings have been achieved:the hydrocarbon-generating parent material in saline-lacustrine source rocks and its hydrocarbon generation mechanism have been identified; a hydrocarbon generation model including interactions among soluble organic matter, kerogen and minerals has been established, which is so called “three-factor controlling” hydrocarbon-generation model; the characteristics and forming mechanisms of fine-grained carbonate reservoirs, deep clastic reservoirs and basement reservoirs have been summarized; and the hydrocarbon accumulation patterns of mixed carbonate reservoirs and deep clastic reservoirs have been built. Guided by these theoretical understandings, a series of exploration targets such as the deep mixed carbonate reservoirs in the Yingxiongling structural belt, deep clastic gas reservoirs in the north Lenghu slope, and basement gas reservoirs in the piedmont of Altyn Tagh mountain have been proved and significant discoveries have been gained. As of April 2019, the cumulative incremental proved OOIP is 2.5×108 tons of equivalent crude oil
