摘要
Reservoir anisotropy is an important indicator of reservoir evaluation which plays an essential role in the oilfield exploration and development.It shows that there be a strong anisotropy of the middle and upper Jurassic reservoir at Santai oilfield both the macro or micro through the statistical analysis to more than 300 samples in nearly 20 wells in the area.And there is anisotropy between the different strata,the heterogeneity of the J3q is more than that of the J2t.The main reasons result to the strong reservior anisotropy in the area conclude proximal deposition,poor reservoir stability,complex compositon of rock,low minerals maturity,poor sorting,mixed rock particle size,intensive matrix,many types of rock and so on.
