来源岩石控制的理论从 source-rock-control 烃累积演变，到有效 source-rock-control 烃累积，并且到高质量的 source-rock-control 烃累积。然而，有问题，高质量的来源岩石是否存在吗？岩石是多么高质量的来源，并且怎么识别他们，还有待于被同意在之上。瞄准了 explorationists 的担心的这个问题，并且拿 Beier 作为一个例子在 Hailaer 盆下垂，这份报纸为高质量的来源岩石的评估定义高质量的来源岩石和更低的限制，由在烃(油)的关系曲线上使用变化点逐出，它由材料平衡原则，对全部的器官的碳( TOC )是计算的。结果证明当 TOC 是低的时，所有来源岩石限制了烃逐出和慢生长率，这样他们不能是高质量的来源岩石。然而，当 TOC 升起到某阀值时，烃逐出与 TOC 显著地增加。这个变化点应该是高质量的来源岩石的更低的限制：有比变化点价值大的 TOC 的那些是高质量的来源岩石。另外，高质量的来源岩石的更低的限制也与在来源岩石，以及影响剩余烃的来源岩石的矿物质部件中的有机物的类型和成熟有关。理论上，高质量的来源岩石的更低的限制取决于地质的条件而非是经常的价值。为简洁和有实行可能的缘故，然而，在这份报纸， TOC=2.0% 被认为是高质量的来源岩石的更低的限制。在工作区域的如此的标准的考试显示在成员 K1n2 和 Nantun 形成的 K1n1 的高质量的来源岩石贡献 76% 和 82% 给产生上油，并且 96% 和 91% 分别地给逐出上油。高质量的来源岩石的分发也是仔细与在这个区域的烃水库的分发有关，表明那高质量的来源摇控制烃累积。

英文摘要：

The theory of ＂source rock control＂ has evolved from source-rock-control hydrocarbon accumulation, to effective source-rock-control hydrocarbon accumulation, and to high-quality source- rock-control hydrocarbon accumulation. However, there are problems, such as whether high-quality source rocks exist or not？ What high-quality source rocks are, and how to identify them, are yet to be agreed upon. Aimed at this issue of concern to explorationists, and taking the Beier Sag in the Hailaer Basin as an example, this paper defines the high-quality source rocks and the lower limit for evaluation of high-quality source rocks, by using the inflection point on the relationship curve of hydrocarbon （oil） expulsion, which is calculated by the material balance principle, versus total organic carbon （TOC）. The results show that when TOC is low, all source rocks have limited hydrocarbon expulsion and slow growth rate, thus they cannot be high-quality source rocks. However, when TOC rises to some threshold, hydrocarbon expulsion increases significantly with TOC. This inflection point should be the lower limit of high-quality source rocks： those with TOC greater than the inflection-point value are high-quality source rocks. In addition, the lower limit of high-quality source rocks is also related to the type and maturity of organic matters in the source rocks, as well as the mineral components of the source rocks affecting the residual hydrocarbons. Theoretically, the lower limit of high-quality source rocks depends on geological conditions rather than being a constant value. However, for the sake of simplicity and practicability, in this paper TOC=2.0% is regarded as the lower limit of high-quality source rocks. The examination of such standard in the work area indicates that the high-quality source rocks in members K~n2 and K~n~ of the Nantun formation contribute 76% and 82% to oil generation, and 96% and 91% to oil expulsion, respectively. The distribution of high-quality source rocks is also closely related to
