摘要
以二连地区阿南油田阿１１断块为例，针对复杂断块油藏的特点，以注采井组为研究对象，综合应用注采动态曲线分析法，辅之以动液面资料、开发生产数据及油层的储渗特性参数等，由渗流机理推断出注入水的主要波及方向就是最小水平主应力的方位，进而可推断出水力裂缝的方位。经钻井井斜推断法及油藏数值模拟法验证，此方法可信度高，现场可操作性强。它为压裂的优化设计以及注水开发井网的调整和完善，提供了新的思路和方法。
Took fault block Ar-11 of Arnan oilfield in Erlian region as an example, took injector-producer group as a research object,applied comprehensively the injectionproduction performance curve analysis method,with the help of working fluid level,production data and reserve-percolation property parameters,etc.,deduced from percolation mechanism that the main sweep direction of the injected water was the azimuth of the minimum horizontal main stress, then, deduced the azimuth of the hydraulic fracture. Verified from drilling deviation deduction method and reservoir numerical simulation method,the performance analysis method for estimating hydraulic azimuth was reliable and operable. It has provided new thought and method for the optimizing design of fracturing and for the adjustment and perfection of water flood development well pattern.
