检测碳酸盐岩储层溶洞系统的累计能量差法
|
摘要
新疆TPT油田一间房组碳酸盐岩储层为缝洞型储层,其缝洞系统在纵横方向上具有较强的非均质性,寻找储层中的溶洞是提高勘探成功率的有效途径之一。提出了一种新的溶洞检测方法——累计能量差法,通过建立溶洞系统的理论地质模型进行地震正演,对TPT油田三维地震数据进行累计能量差处理后,通过对过井剖面与钻探成果的比较,证实了该方法是非常有效和精确的,能成功地识别和检测储层中的溶洞发育位置和特征。提取了一间房组地震能量差检测值,形成碳酸盐岩储层的溶洞发育平面图,其对后期勘探和开发具有积极的指导意义。
The carbonate rock reservoir of Yijianfang Formation is vug-fracture one in TPT oilfield in Xinjiang,in the system,there is stronger heterogeneity in vertical and horizontal direction.Seeking the vugs in the reservoir is an effective approach to improve prospecting successful rate.In this paper,one kind of new vug detecting method is put forward,i.e,cumulative energy difference,seismic forward modeling is carried out by building the theory geology model of vug system,according to application effect,the developing location and characteristic of vugs in reservoir are successfully recognized and inspected.3D seismic data of TPT oilfield is dealt with cumulative energy difference,demonstrating that detecting and actual results fit very much through comparing the section through well with drilling production,confirming the method is effective and accurate.vug developing zone of Yijianfang Formation is recognized by adopting the method to pick up the seismic prediction values,the exploration and exploitation have active guiding significance to later stage.
