莫西庄地区三工河组二段储层特征评价

三工河组二段砂体为莫西庄地区的主要含油储层，分布相对较稳定.三工河组二段含油砂体分为三工河组二段一砂体和三工河组二段一砂体两套砂体，分布稳定.文章通过分析沉积特征、物性特征、孔隙类型和孔喉特征，对这两套含油储层进行了系统的评价，认为J1s12含油储层属中—差型储层，J1s12含油储层为中等储层.在综合评价的基础上，通过地震反演，预测了莫西庄地区主力含油砂体厚度的分布.

Charater appraisal of section2 reservoir, sangonghe group, moxizhuang area

The sandstone in section 2,Sangonghe Group is the major reservoir in Moxizhuang Area,with a sable distribution.The oil-bearing sandstone in section 2 of Sangonghe Group is divided into J1s12 reservoir and J1s22 reservoir.Through analysis on the sedimentation characters,physical characters,pore style and pore throat characters,the author makes a systematic appraisal toward these two oil-bearing reservoirs.And it is concluded that J1s12 is a moderate-bad reservoir,while the J1s22 is a moderate reservoir.On the basis of comprehensive appraisal,the author predicts the thickness distribution of major oil-bearing sandstone in Moxizhuang Area via seismic inversion.
