摘　　要：乌里雅斯太油田是近年来华北油田发现的相对整装、规模相对较大的低孔特低渗透油藏。由于该区储层物性差,非均质性强,存在较大开发风险。为合理、有效地开发该油藏,在常规研究的基础上,重点开展了沉积相及沉积微相研究、天然裂缝发育状况研究、恒速压汞室内实验及可动流体饱和度研究、开发试验井组试验以及合理井网井距、合理产能规模等开发技术政策研究工作,落实了该区有利建产层位及建产规模,实现了该油田的合理、有效开发。Wuliyasitai Oilfield was a relatively uncompartmentalized large reservoir with low porosity and extremely low permeability in Huabei Oilfield.This reservoir had poor physical property and high heterogeneity which induced high risk of development.For the purpose of developing the reservoir more reasonably and effectively,on the basis of regular work,great effort was made on such laboratory experiment researches as development well experiments,sedimentary facies and microfacies,primary fracture development,movable fluid saturation and constant rate mercury penetration.Moreover,development technoloy rules researches such as rational well network,rational spacing between wells and rational productivity pattern were established.Finally,favorable producing reservoirs and well pattern are established which realize the rational and effective development of the oilfield.
