摘要:
准噶尔盆地阜东斜坡区侏罗系石树沟群河道砂体发育,具有“断裂通源、岩性控藏”的特征,不同砂体间产量差异大,常规技术方法预测高产油藏困难。在新采集阜东5井区三维“两宽一高”地震资料基础上,通过分析河道砂岩地震响应特征,首先在河道砂岩内运用叠前AVO派生属性区分油水,定性识别出油层;其次,运用核磁共振测井的有效孔隙度和渗透率综合计算得到孔渗参数,与储集层产量建立相关关系,并在油层内通过孔渗参数地质统计学反演区分出低产、中产和高产油层,定量预测产量,最终得到高产油层预测结果。形成了阜东斜坡区侏罗系河道砂岩高产储集层预测配套技术,有效指导了研究区后期高产井位的部署。
Abstract:
The Jurassic Shishugou group in Fudong slope area of Junggar basin is characterized by the development of channel-type sandbodies, which has the characteristics of “fault connected with oil source & reservoir controlled by lithology”. The production varies greatly among different sandbodies and it is difficult to predict high-yield reservoirs with conventional techniques and methods. On the basis of newly acquired “high density, wide azimuth and broadband” 3D seismic data of Wellblock Fudong-5, this paper analyzes the seismic response characteristics of channel sandstones. Firstly, the pre-stack AVO derivative attributes are used to distinguish oil and water in channel sandstones and the reservoirs are identified qualitatively; secondly, the effective porosity and permeability obtained from NMR logging are used to calculate porosity and permeability parameters comprehensively, and the correlation with the reservoir production is established; then the low-yield, medium-yield and high-yield oil layers can be distinguished in the reservoir by the geostatistical inversion and the production can be predicted quantitatively. Finally, the prediction results of high-yield reservoir can be obtained. The matching technology for predicting high-yield reservoirs of Jurassic channel sandstones in Fudong slope area has been integrated and formed, which can effectively guide the deployment of high-yield wells in the later period of the study area
