A new type practical hydrocarbon expulsion model is suggested in this paper. According to this model, hydrocarbon expulsion can be divided into monofactor and bifactor two stages. During the monofactor hydrocarbon expulsion stage, oil saturation is the only controling factor to the expulsion of hydrocarbons, and the driving force of hydrocarbon expulsion is compaction; in the difactor hydrocarbon expulsion stage, the expulsion of hydrocarbons is doubly controlled by critical oil saturation and critical...

A new type practical hydrocarbon expulsion model is suggested in this paper. According to this model, hydrocarbon expulsion can be divided into monofactor and bifactor two stages. During the monofactor hydrocarbon expulsion stage, oil saturation is the only controling factor to the expulsion of hydrocarbons, and the driving force of hydrocarbon expulsion is compaction; in the difactor hydrocarbon expulsion stage, the expulsion of hydrocarbons is doubly controlled by critical oil saturation and critical fracturing pressure, and the driving force of hydrocarbon expulsion is fluid overpressure. This breaks through the limitations to monostage or monofactor hydrocarbon expulsion simulation before, refrains from studying on complex facies during hydrocarbon expulsion, and avoids the accumulation of errors. The key of the model is dividing standards of the two stages, the determination of critical oil saturation ( S c) and critical fracturing pressure ( p c), and the acquirement of fluid overpressure. This model has obtained good application effects during the quantitative evaluation on the hydrocabon source rocks of the Jiazhangsi Sag in the eastern depression of the Liaohe Basin.

本文提出了一种新型实用的排烃模拟模型。根据该模型可将排烃分为单因素排烃和双因素排烃两个阶段。在单因素排烃阶段,含油饱和度是烃类排出的唯一控制因素,排烃的动力是压实作用;在双因素排烃阶段,排烃受临界含油饱和度和临界破裂压力的双重控制,排烃的动力是流体超压。这突破了以往单阶段或单因素排烃模拟研究的局限并避开了对排烃复杂相态的研究,避免了误差的积累。该模型的关键是两阶段的划分标准及临界含油饱和度(Sc)及临界破裂压力(pc)的确定和流体超压的求取。该模型在辽河盆地东部凹陷驾掌寺洼陷烃源岩定量评价中取得了良好的应用效果。

A new model is presented for characterizing the propagation of long fatigue crack based on the analysis of test data of LZ50 carbon steel.The cracking threshold,fracture roughness and cyclic ratio are incorporated in the model.The behaviour of fatigue crack propagation nearby the cracking threshold is well reflected.And in the high stress intensity factor range the growth rate growing up to the critical fracturing point is well also revealed.The present model is derived from a comparing analysis of the existent models,i.e. Paris-Erdogan equation,Forman-Kearney-Engle model,and Elber equation.Paris-Erdogan equation is invalid to the regimes of nearby the cracking threshold and the stress intensity factor range.Forman-Kearney-Engle model is also invalid to the regime nearby the cracking threshold.And the Elber equation has a big deviation to the critical fracturing point in the high stress intensity factor range.All of the disadvantages in the existent models have been well overcome by the present model.
