构造、沉积与成岩综合一体化模式的建立——以松南梨树地区后五家户气田为例

The Establishment of Intrgrated Model on Structure,Deposition and Diagenesis

石油与天然气地质勘探工作的最终目的就是对某个地区的构造、沉积及成岩进行综合评价，以便准确地寻找新的勘探靶区或油田。然而，长期以来人们在这方面的研究是各自独立的进行，这对新的勘探地区进行综合评价与预测，尤其是精确布井产生了一定的困难。因而，多学科的综合研究则是当前石油与天然气勘探的主要方法与内容。作者以松辽盆地南部梨树坳陷后五家户气田为例。从盆地的构造演化、沉积体系分布的分析入手，研究了该区的主要产气层位的成岩特征及成岩演化机理，建立了构造、沉积与成岩三者的综合一体化模式，进而对该区的储层发育、成因与展布进行了详细的分析。这一研究思路与方法或许是今后油气勘探研究的方向与主体内容之一。

The final purpose of explorion work in petroluem geology is synthetically to appraise a certain field on its structure,deposition and diagenesis in order to find new area and oilfield for next exploring step.However,this study in petroleum geology has been Carried out independently for a long time.If we used this method of thinking,It would be very difficult for us to appraise and predict new field of exploration,especially to determine the location of exploration well synthetically.Today the main method and content of petroleum exploration are to integrate knowledge of multidiscipline for studing a certain qeustion.The author took the Houwujiahu gas fild as the example exposed the diagenesis characteristic of this area had set up a integrated model through the study of structure and deposition features.Furthermore,the author made the detailed research on reserioir development,genesis and distribution of this area.The way and method of established integrated model may be one of the main study content and direction of hydrocarbon exploration in the future.
