摘要
水力压裂在低渗油气藏增产措施中占有相当大的比重 ,而且是提高油气采收率的主要方法。因此对水力压裂研究 ,尤其是压裂后裂缝诊断研究就尤为必要 ,它可以验证或修正水力压裂中使用的模型、选择压裂液、确定加砂量、加砂程序以及采用的工艺 ,进而降低压裂成本和提高油气采收率 ,达到合理高效开发油气田的目的。本文通过间接的压力恢复试井和生产动态分析法、净压力拟合法以及三维水力压裂模型来诊断水力压裂后裂缝缝高 缝长 。
Hydraudic Fracturing plays an important role in increasing production of with Low permeability reservoir and it also is the prime approach to raising the rate of oil-gas extraction.As a result,it is vital to make research on hydroudic fracturing.Through different test such as testing well by recovering pressure indirectly and analysis of oil well's preformance,the height and Length of fracture of hydraudic fracturing are diagnozed so as to provide full and essential information for hydraudic fracturing.
