新疆—区石炭系火山岩油藏注采动态特征研究
|
摘要
通过参阅大量的相关文献,细致分析了复杂的火山岩储集层形成过程,进行了相关的室内分析化验,仔细研究了新疆一区石炭系的开发历程。并以此为基础讨论火山岩油藏的地质特征,争取找到其油水运动的规律,从而合理全面的进行注采动态研究,并为进一步开发找到合理依据。力求找出适应火山岩变质岩油藏注水动态开发的最佳方案。为此类油藏在今后的注水动态开发的适应性及可行性方面做一些有益依据。
火山岩油藏目前开发中暴露出来的问题,反映出对裂缝与基质的渗流机理尚缺乏充分认识,合理有效的注水方式尚需进一步论证,油井开发方式也需进一步探讨。由于火山岩储集层形成过程复杂,形成途径多样,其结构更是复杂、差异巨大,由此导致的严重非均质性,给这类油藏的开发造成极大的难度和复杂多样的注采动态特征。
我们通过对国内火山岩变质岩类油藏开发历史的综合研究,特别针对新疆一区石炭系火山岩油藏,首先,仔细研究其油藏的基本地质情况,无论是油藏构造,储层岩性的特性,储集空间的特性,油藏渗流特征,流体性质还是油藏的整体特征都做了具体仔细的分析。其次,根据新疆一区石炭系火山岩油藏的开发历程,进一步研究其开采的动态特征,找到她的油水运动规律。最后,得到了对新疆一区石炭系火山岩油藏进一步开发的认识。从而扩展开来,对此类火山岩变质岩油藏提出了注水开发的新的思路。
在这个研究过程中,我们引用了大量的动态开发实例,进行横、纵向的对比,进一步分析裂缝在注水开发中的影响。从宏观和微观上得到油水的运动规律,为今后的火山岩油藏补充地层能量,改变水驱油方向和效率,探究高含水后期合理的注采方式,改善油藏开发效果,提供了有力的借鉴。
Through the reference of massive related literature, we have carefully analyzed the forming process of the complex volcanic reservoirs, carried on a series of related indoor analysis and assays, and carefully studied the development course of Xinjiang Yiqu area Carboniferous reservoir. Taking this as the foundation we discussed the geological features of volcanic reservoirs, and tried to find the movement rules of the fluid in it, so that we could carry on the dynamic research about the injection and production reasonably and comprehensively, further more we could find the reasonable basis for the further development. We made every effort to set up the optimum plan, which adapts volcanic and metamorphic reservoirs well for water-flooding development. These can be beneficial bases for this kind of reservoirs in the next step of research for the adaptability and the feasibility of water-injection development.
The problems exposed in the present development of volcanic reservoirs reflect that we have not know the transfusion mechanism in fracture and the matrix well enough, the reasonable and effective water-flooding patterns are still necessary to be studied, the oil well development modes also need to be further discussed. Because of the complicated forming process and diverse forming ways, the structure of volcanic reservoirs is very complicated with huge difference, which has caused its serious anisotropy and results in the enormous difficulty and various injection-production performances during the development.
We studied the development histories of many domestic volcanic and metamorphic reservoirs comprehensively, especially focused on the Xinjiang Yiqu area Carboniferous volcanic reservoir. Firstly, we studied its basic geological situation carefully, including its structural features, lothological characters, the reservoir space characters, the transfusion characters, the fluid nature and the overall characteristic. Next, according to its development course, we concluded its rules of the oil-water movement by the further study on its dynamic characteristic of the production. Finally, we obtained the ideas how to develop Xinjiang Yiqu Carboniferous volcanic reservoir reasonably. On the basis of this, we generalized some new ideas for water-flooding development targeting to common volcanic and metamorphic reservoirs.
In this research process, we have quoted a large numbers of dynamic development examples, contrasted each other longitudinally and horizontally, then made further analysis of the influence of the fractures in water-injection development. Consequently, macroscopic and microscopic laws of oil-water movement were educed, as can be used for the reference on many aspects for the future development of volcanic reservoirs, such as the supplement of producing energy, the change of water-oil displacement direction, the improvement of efficiency, as well as the discussion of reasonable injection-production way during the later high watery period and the improvement of final development effect.
