摘要

松辽盆地南部梨树断陷基底结构复杂,潜山形成机制多样,潜山的分布预测、储集性能评价及油气成藏规律研究是进一步评价潜山勘探潜力面临的主要问题。在钻井岩心分析测试的基础上,运用地质、地球物理技术,研究了潜山油气成藏主控因素。结果表明:潜山的形成主要与控盆断裂、褶皱构造、反转构造的发育相关;基岩储层普遍低孔低渗,构造裂缝是改善储集性能的关键,总体上越靠近断裂带,裂缝越发育;潜山能否富集成藏取决于基底与烃源的接触方式、裂缝的方向及开启性与烃类运移方式是否一致;桑北、桑南基底潜山直接与烃源岩接触,供烃有利,有利于形成基底油气藏;中央构造带、七棵树和秦家屯等地区基底潜山幅度低,距离大断裂位置相对较远,基底主要以断层和不整合面与烃源岩呈间接接触,对基岩油气成藏相对有利;通过该研究在梨树断陷识别出20多个潜山圈闭,显示出良好的勘探前景,西部桑树台潜山带和中央构造潜山带为下步潜山勘探的重点区带。研究成果可为该区基岩油气资源预测与勘探提供重要理论支撑。

Abstract

The Lishu fault depression in the southern Songliao Basin is characterized by complex bedrock structure and diverse buried hill development mechanisms. The major challenges for further evaluation of buried hill hydrocarbon exploration potential include buried hill distribution prediction, reservoir performance evaluation and hydrocarbon accumulation patterns. Geological and geophysical techniques were adopted to analyze the main controlling factors of buried-hill hydrocarbon accumulation based on the drilling core test. Result indicates that the buried hill development is dependent on basin-controlling fault, fold structure and reverse structure. Bedrock reservoir is generally featured by low porosity and low permeability, and structural fractures are the key aspect to improving reservoir performance. Generally, there is a increasing trend for the fracture development closer to the fault zone. Hydrocarbon enrichment and accumulation in the buried hill depends on the contact patterns of bedrock and source rock, consistency between fracture direction, opening level and hydrocarbon migration mode. There is a direct contact between bedrock buried hill and source rock in Sangbei and Sangnan, and favorable hydrocarbon supply condition is conductive to bedrock hydrocarbon accumulation. The bedrock buried hill shows a relatively low amplitude in the central tectonic belt, Qikeshu, Qinjiatun and other regions which are far away from the major fault. The basement contacts with source rock as fault and unconformity, which is favorable to bedrock hydrocarbon accumulation. A total of more than 20 buried hill traps were identified in the Lishu fault depression, indicating great hydrocarbon exploration prospect. The western Sangshutai buried hill zone and the central structural buried hill zone are considered as the major zones for further hydrocarbon accumulation. This research could provide certain theoretical reference for the bedrock hydrocarbon resource prediction and exploration.

Key words： bedrock buried hill; hydrocarbon accumulation condition; main-controlling factor of hydrocarbon accumulation; favorable zone; buried hill hydrocarbon exploration in Lishu fault depression
