摘要
复杂的烃水库在从在早阶段形成的烃水库的多重结构的改变，改革和破坏形成的中国的附加的盆广泛地发展了。他们被陷井调整，部件变化，阶段变换，和规模改革当前描绘。这为由在烃水库形成以后并且为预言揭示进化机制指导当前的烃探索是重要的仍然是潜在的资源。基于很多座复杂的烃水库的分析，有四个地质的特征，控制在早阶段形成的烃水库的破坏的度：在构造进化期间为油和气体封上的构造事件紧张，频率，时间和 caprock。研究看那越大构造事件紧张，越多经常构造事件，以后的最后构造事件，越多更弱为油和气体封上的 caprock，并且更大在早阶段的破坏的烃的体积。基于关于烃水库破坏机制，构造重迭的一个地质的模型和评估潜在的留下的复杂的烃水库的一个数学模型的主要控制因素的研究被建立了。断言方法和技术过程在 Tarim 盆的 Tazhong 区域被使用，在烃累积的四个阶段和烃改变的三个阶段发生了的地方。Geohistorical 烃累积到达了 31.84 亿吨， 12.71 亿吨被破坏。仍然是为探索可得到的资源的全部的体积是 19 亿吨。
Complex hydrocarbon reservoirs developed widely in the superimposed basins of China formed from multiple structural alterations, reformation and destruction of hydrocarbon reservoirs formed at early stages. They are characterized currently by trap adjustment, component variation, phase conversion, and scale reformation. This is significant for guiding current hydrocarbon exploration by revealing evolution mechanisms after hydrocarbon reservoir formation and for predicting remaining potential resources. Based on the analysis of a number of complex hydrocarbon reservoirs, there are four geologic features controlling the degree of destruction of hydrocarbon reservoirs formed at early stages： tectonic event intensity, frequency, time and caprock sealing for oil and gas during tectonic evolution. Research shows that the larger the tectonic event intensity, the more frequent the tectonic event, the later the last tectonic event, the weaker the caprock sealing for oil and gas, and the greater the volume of destroyed hydrocarbons in the early stages. Based on research on the main controlling factors of hydrocarbon reservoir destruction mechanisms, a geological model of tectonic superimposition and a mathematical model evaluating potential remaining complex hydrocarbon reservoirs have been established. The predication method and technical procedures were applied in the Tazhong area of Tarim Basin, where four stages of hydrocarbon accumulation and three stages of hydrocarbon alteration occurred. Geohistorical hydrocarbon accumulation reached 3.184 billion tons, of which 1.271 billion tons were destroyed. The total volume of remaining resources available for exploration is -1.9 billion tons.
