【摘要】 莫北油气田三工河组油气藏油气水分布主要受构造控制 ,在J1S21油藏受岩相控制较明显。以地震、地质研究及试油、试采资料为依据 ,对试油资料不足的区块结合五种经验判别方法 (Φ1参数判别法、C5+ 含量判别法、C1 C5+ 比值判别法、F参数等级分类判别法和Z因子判别法 )进行综合分析。莫北 2井区J1S21砂层油气界面仍需通过评价井MB2 0 0 3井试油才能落实 ,油气藏类型为层状低孔低渗、带边水的凝析油气藏 ;J1S22 砂层据开发评价井MB2 0 0 3井测井曲线和三维地震解释 ,结合该井试油成果资料 ,确定了油水界面 ,油气藏类型为带油环带边底水的低孔低渗凝析气藏。莫北 9井区块J1S21和J1S22 分属两个不同油藏。J1S22 为构造油藏 ,J1S21为受岩性控制的构造油藏更多还原

【Abstract】 Oil-gas-water distribution system about SANGONGHE group of oil-gas reservior of MUOBEI oil-gas field is mainly controlled by structure,and it is obvious that J 1S 2 1 reservior is controlled by lithofacies.According to seismic interpretation,geology research,oil-gas test and producing test materials,the section for lack of producing test material is analysed synthetically by means of five experiential methods of decision(Φ 1 parameter method of decision?C5+content method of decision?C 1/C 5 + ratio method of decision?F parameter rank sort method of decision and Z factor method of decision).Oil-gas surface of J 1S 2 1 sand body of MB2 well section is determined by nothing but oil-test for evaluation well MB2003,and oil-gas reservior type is a stratified-condensate reservior with low porosity?low permeability and boundary water. with the help of logging curve and 3-D seismic interpretation and oil-test material, oil-water surface of J 1S 2 2 sand body is determined, oil-gas reservior type is a condensate reservior with oil ring ?boundary-bottom water ? low porosity and low permeability. J 1S 2 1 reservior and J 1S 2 2 reservior belong to two oil reserviors. J 1S 2 1 reservior is a structure oil reservior controlled by lithofacies, J 1S 2 2 reservior is a structure oil reservior.更多还原
