莫西庄油田三工河组砂体精细对比与油气富集规律

The Precise Comparision and the Hydrocarbon Accumlation Regularity of Sangonghe Group Moxizhuang Oilfield

莫西庄地区J_1s2储集砂体具有个数多、厚度大的特征。利用沉积微相划分和储层精细对比方法,按沉积物源与古水流方向分区对储层砂体展布和精细对比进行了研究,总结了J_1s2储集砂体油气富集规律。莫西庄地区含油层段为J_1s2~1和J_1s2~2砂组,J_1s2~2砂组油气主要储集在J_1s2^(2-2)砂体中,并在Z106井、Z1井、Z107井构造位置富集。J_1s2~1砂组的含油层段主要位于上部J_1s2^(1-1)和J_1s2^(1-2)砂体中,其中J_1s2^(1-2)砂体为主力含油砂体,在莫西庄地区普遍含油。

A large quantity o~ thicksand bodies are characteristics of Jls2 reservoir sand body in Moxizhuang district. By means of sedimentary microfacies division and precise reservoir comparison as well as to directions of the sedimentary source and paleocurrents, the distrihution and precise comparison of reservoir sand bodies are researched zonally, and the hydrocarbon accumulation regularity of Jxs2 reservoir sand body is summarized. The oil-bearing segments in Moxizhuang district are the Jls21 and Jls22 sand groups. Hydrocarbon of Jls22 sand group is mainly in J1 s2e 2 sand body, accumulating in the structural position of well Z 106, Z 1, as well as Z 107. The oil-hearing segments of J1 s21 sand group is mainly in the upper J1 s211 and Jl s21-2 sand bodies, where Jls212 sand body is the main oil-bearing sand body which is generally oily in Moxizhuang district.
