Based on the investigations of carbonate source rocks, which had expelled oil and gas in the past, and studies of simulation experiments about the generating and expelling hydrocarbons in carbonate rock at a series of temperature and pressure conditions. In this paper, the following novel points have been submitted:1.The expulsion energy of carbonate source rock mainly come from the increasing pressure within itself caused by the great increase in molar volumes with the generating and further cracking of hydrocarbons. However, the hydrocarbons would still be sealed untill micro-fracture appears in the rock caused by regional tectogene or exogenetic actions. In those cases, only by relying on the initiation of outside force, intrinsic pressure does be the expulsion energy. Compaction doesn't be expulsion factor due to the diagenesis-catagenesis particularities of carbonate rocks.2. Although the oil-generating time of carbonate source rock is earlier, generally the immature crude oil has been generated at R_0≈0.45%, yet the oil-expelling time would be delayed owing to missing the micro-fracture in rocks. Therefore, hydrocarbon-expelling time of carbonate source rock is controlled mainly by its fracturing time, not by its thermal evolutional stage.3. Basically, the phases of hydrocarbons of carbonate source rock during primary migration are oil and gas. It may be suggested that the release of either mineral crystallization water or free water have not being in catagenetic and metagenetic stages of carbonate rocks.

通过典型碳酸盐型油气田的野外调查研究和对未成熟碳酸盐生油岩在外加温、外加压条件下所作的生烃一排烃模拟实验结果,获得下列新的认识:(1)碳酸盐烃源岩排烃的驱动力主要不是来自地层的压实作用,而是由于生烃过程中分子体积膨胀所产生的内应力(即生烃增压)。该应力与周围环境形成潜在的压力梯度,这是排驱动力的内在因素。但是单凭此因素尚不足以造成排烃,只有当后来烃源层受到外力作用(如导致微裂隙产生的区域性构造活动、造成溶蚀交代出现缝缝洞洞的地下水活动等)生成裂隙空间,并在源岩与裂隙间出现真正的压差时,才引发烃源层中积蓄的应力释放,从而造成排烃。因此、区域性的外力作用是排烃的控制因素。(2)碳酸盐烃源岩中生烃时间甚早,一般在R_0为0.45%左右时就开始生成低熟原油。但由于碳酸岩岩石粒间孔径甚小,虽有低熟油生成,却不能象泥质烃源岩那样在其烃浓度超过最低石油运移饱和度时就可排烃。事实证明,无论生烃量多大,只要碳酸盐烃源岩中不出现有效的通道,排烃作用可能永远不会进行。因此,当碳酸盐烃源岩中油气生成之后,裂隙发生的时间就成为决定碳酸盐烃源岩排烃时间的基本因素。(3)碳酸盐烃源岩中烃类初次运移基本上是以全烃相进行的,这与碳酸盐岩在后?

Many oil and gas wells have high formation temperature. For obtaining optimum fracturing result, it is necessary to consider the effect of the temperature change along the fracture on the properties and fluid loss speed of fracturing liquid in fracturing design. For this reason, the temperature field mode inside the fracture is established for determining the temperature distribution of the fracturing fluid at any given moment. First, two partial differential equations is established for describing the temperature distribution in the fractured formation rock based on thermal energy equilibrum, one is suitable for permeable rock, and the other is for compacted rock. Then, the heat flux density expressions of the permeable and compacted fracture surfaces are obtained by the Laplace Transform of these two partial differential equations. The calculation and analysis of an example show that the heat flux density is decreased with the increase of fracturing time, to the permeable fracture surface, the greater the fluid loss coefficient of fracturing fluid and formation porosity, the lower the heat flux density at any given moment and position. The two heat flux density expressions can be used for establishing the temperature field model of three dimensional fracture.

It is shown that the headon collision of two detonation waves greatly reduces the time needed for fracturing, and increases the radial expansion speed at the colliding positions of the tubes, and the fracturing time at colliding positions calculated from the Taylor criterion is indeed significantly reduced compared with that at noncolliding positions.

利用闪光X光照相、光学高速分幅照相实验,测得了金属圆管在两个爆轰波对碰后产物驱动外壳的膨胀、变形过程,该过程表明爆轰波对碰作用使得对碰处金属圆管相对贯穿断裂时间明显提前,对碰处金属圆管径向膨胀速度较非对碰处明显增加。利用拉格朗日二维流体动力学程序TTD2C,数值模拟了对碰驱动过程,计算结果与实验结果符合很好,且用Taylor断裂判据得到的金属圆管相对贯穿断裂时间也明显提前。
