摘要
随着对地应力认识的逐步加深,它在油气勘探开发中的作用日益受到重视。本文运用多种方法确定了巴喀油田现代最大主应力的方向,利用水力压裂资料估算了三个方向主应力的大小及分布规律,力图客观真实地反映出巴喀油田现今地应力的状况,并阐述了裂缝与古今地应力的关系及在不同开发时期的作用。在此基础上,结合巴喀油田的生产情况,提出了有关井网调整、压裂改造和注水的一些看法。
In pace with in-situ stress knowledge deepening, it is increasingly paied attention to the exploration and development of oil and gas. This paper utilizes varied methods to determine the direction of maximum principal stress nowdays in Baka Oilfield, makes use of hydraulic fracturing data to estimate the sizes and distribution laws of principal stresses in three directions, reflects objectively and authentically recent in-situ stress conditions for Baka Oilfield, and elaborates the relation between fracture, ancient-modern in-situ stress and the function of different development periods. On the basis of them, it integrates production situation of Baka Oilfield, and put forward some opinions on well pattern adjustment, fracturing transformation and water injection.
