基于地震及动态资料评价复杂断块油田潜力

Evaluating the Potential Force of Complex Fault Block Oilfields Based on Seismic and Dynamic Data

海上复杂断块油田面临着构造破碎、油水关系复杂、测试资料少、认识程度不足等难题,严重制约着油田的滚动开发。针对该问题,以渤海Z油田M断块油藏为例,从三维地震资料分析入手,结合油藏动态资料,利用油藏工程和数值模拟方法研究了该断块的潜力储量规模及其分布范围,从多角度论证了潜力储量的可靠性。研究结果指导了油田开发兼评价井的部署和滚动挖潜,实现了断块油田的增储上产,取得了较好的应用效果,对复杂断块油田开发过程中类似问题的解决具有借鉴意义。

Offshore complex fault-block oilfields faced with the problems of broken structures,complicated oil-water relationship,less test data and insufficient understanding,it seriously restricted the rolling development of the oilfields.To solve the problems and by taking M Fault Block in Bohai Z Oilfield as an example,starting from the analysis of 3 Dseismic data and combined with the dynamic characteristics of reservoir production,the potential reserves of the block and the distribution area were studied by using the reservoir engineering and numerical simulation method,which further demonstrated the reliability of potential reserves.The results of the study can guide the deployment and rolling development for the development and evaluation wells,which enhances the reserves and production,good application results are achieved,it provides reference for solving the similar problems in development of complex fault block oilfields.
