摘要
滩海地区成藏条件较为复杂,主要的烃源岩层段为沙三段、沙一段和东三段,成熟度较好,主体都已达到生油门限,可以为全区提供丰富的油气。本区储盖组合主要集中于沙河街组与东营组,形成多种组合形式。同时,本区圈闭类型多样,油气主要围绕两个生油洼陷(海南洼陷与盖州滩洼陷)聚集。
     对滩海西部、中部和东部的三个典型地区油气成藏特点进行分析,主要取得以下认识:(1)在滩海西部笔架岭地区,部分烃源岩有较好的生烃能力,但油气主要来源于邻近海南洼陷深部位,储层集中于沙一、二段与东三段,砂体发育良好,连通性质佳,由于地层倾缓,断层欠发育,所以油气侧向运移为油气成藏的主要特点;(2)在滩海中部月东-海南地区,油气具有双向来源特点,断裂在本区尤其发育,覆盖全区范围,来自海南洼陷和盖州滩洼陷的油气通过断裂运移至本区成藏。部分断裂长期活跃,油气的长期保存或保存条件控制油气聚集是本区油气成藏的主要特点;(3)在滩海东部太阳岛-葵花岛地区,油气主要来源于邻近盖州滩洼陷,储层主要为东营组。且由于地层陡峭,使储层与深部烃源岩沟通程度不好,只能依靠油源断裂,因此油气垂向运移是本区油气成藏主要特点。
     通过典型地区油气成藏特点解剖,总结滩海地区油气成藏不利条件:西部地区主要的不利条件是配套条件与圈闭条件;中部地区主要的不利条件是储层条件和保存条件;东部地区则是储层条件和输导条件。对成藏条件进行整理,把滩海地区成藏条件分为五大类(烃源岩条件、储层条件、圈闭条件、保存条件和配套条件),并通过地质风险概率法定量化五大类成藏条件,运用多元线性回归模型原理,在SPSS软件上进行拟合,计算得到油气成藏条件与油气成藏之间的影响关系方程以及对成藏影响最大的条件。
     通过成藏条件综合研究、油气成藏不利因素与计算结果的对比等分析,确定油气成藏主控因素:在西部地区是配套条件(储盖层配置)、中部地区是保存条件(断裂破坏程度)、东部地区是储层条件(与烃源岩沟通程度)。
In Liaohe tidal zone, oil-gas reservoir conditions is more complex. The main source rocks include E2S3, E2S1, E2d3, and gather in two sag(Hainan sag and Gaizhoutan sag). Maturity of source rocks is better, the majority has reached the limit throttle Health and can provide a wealth of oil and gas region. Reservoir-seal combination in this area focuses on E2S and E2d, and come in many forms. At the same time, the region has multiple types of traps, oil and gas gather around the two sag.
     Analysis of the Liaohe Tidal Zone western, central and eastern areas of the three typical characteristics of hydrocarbon accumulation, Recognized: (1) In Bijialing of the tidal zone west, part of hydrocarbon source rocks have good hydrocarbon generation capacity, but the oil and gas mainly come from the neighboring deep depression of Hainan, and focus on the E2d3 E2S1+2 reservoir. Sand body developed well, and had the nature of good connectivity. As a result of dumping stratigraphy relief and dueing to development of faults, so the main hydrocarbon accumulation is characterized by lateral migration; (2) In Yuedong– Hainan of the central tidal zone, hydrocarbon come from two sag, and fracture develop well particularly, coverd with the whole region. The migration was vertical through the fracture. As part of long-term active fault, the main features was that the controlled storage conditions impact accumulation in this area. (3) In Sun Island–Sunflower Island of tidal zone east, the oil and gas mainly come from the neighboring deep depression of gaizhoutan, and focus on the E2d reservoir. Stratigraphy was so steep that links between source rocks and reservoir was bad, and then they communicated only through the fracture. Thus oil and gas vertical migration is one of the main characteristics of hydrocarbon accumulation.
     Through analysis of a typical region, adverse conditions of hydrocarbon accumulation was sumed up in beach area: The main disadvantage of the western region provided that the associated conditions and trap; reservoir、preservation conditions and trap become the main adverse conditions in the central region; The eastern region was reservoir and conducting conditions. conditions of accumulation collated into the Liaohe tidal zone was divided into five major categories, including source rocks, reservoir, trap, storage and matching. And then they were quantified by the geological risk probability method. Using multiple linear regression model, it get affecting relationship equation between hydrocarbon accumulation and accumulation condition through fitting in the SPSS software. And the greatest impact conditions was calculated.
     At last it determined the controlling factors of oil and gas accumulation through the integrated study of reservoir conditions and comparison analysis between accumulation adverse factors and the results. The controlling factors of oil and gas accumulation was matching conditions (reservoir cap configuration) in the western region; was preserve (the degree of fracture damage) in central region; was reservoir (the degree to communicate with the of source rock) in eastern region.
