断块油藏储层连通性分析和综合研究
Analysis and comprehensive study of reservoir connectivity in fault block reservoirs
摘要
Abstract
The P oilfield,situated within the Bonan low uplift belt in Bohai Bay,features multiple faults near the strike-slip faults in high structural regions.Following over a decade of development and production,the main issue in these elevated parts of the oilfield is the weak injection-production connectivity among well networks and the inconsistency between production performance response and fault recognition.To elucidate the fault distribution patterns in these high structural areas and address the poor connectivity within the current injection-production well network,numerical simulation technology is employed,leveraging production performance data from well networks and incorporating new insights on complex strike-slip fault zones.Furthermore,the study is also corroborated by utilizing seismic data for cross-validation.The findings reveal that numerous hidden fault systems have developed close to the strike-slip faults in the P oilfield,hindering the advancement of injected water,leading to overpressure at the injection well end and pressure loss at the production well end,ultimately resulting in suboptimal oil production efficiency.This study can offer valuable insights for future adjustments to wells in the high structural regions of the P oilfield,aiming to exploit the remaining oil potential.关键词
