摘要:神木气田是鄂尔多斯盆地东部长庆气区增储上产的重要组成部分。米38区块是神木气田上产的重要区块,为了更好给气田开发提供技术支撑,依靠实验研究，数据分析等测试手段,研究了米38区主力层段的储层特征,通过对有效砂体的厚度、规模、分布频率、有效砂体平面展布特征研究,编制了砂体和有效砂体平面等厚图，从而认识到米38区山2段、太原组的有效砂体展布规律。研究认为:米38区山2段,太原组储层均属于低孔低渗储层,山2段和太原组有效砂体在米38区内广泛分布,山2段砂地比较大但净毛比较小，太原组比山2段有效砂体更为发育。

Abstract: The Shenmu gas field is an
important part of increasing reserves and increasing production in the Changqing
gas field in the east of Ordos Basin. In
order to provide technical support for the development of Shenmu gas field, the
reservoir characteristics of the main reservoir in Mi38 area are studied by
means of experimental research and data analysis, by studying the thickness,
scale, distribution frequency and plane distribution characteristics of
effective sand bodies, the plane isopach maps of effective sand bodies and
effective sand bodies are worked out, therefore, the distribution law of
effective sand bodies in Shan 2 and Taiyuan Formation in Mi38 area is
recognized. The study shows that the reservoirs of Shan 2 member and Taiyuan Formation
in Mi38 area are low porosity and low permeability, the effective sand bodies
of Shan 2 member and Taiyuan formation are widely distributed in mi 38 area,
the sand body of Shan 2 member is larger but the net wool is smaller, the
effective sand body of Taiyuan formation is more developed than that of Shan 2
member.
Keywords: Reservoir characteristics;
Pore Structure Combination; effective sand body distribution;
