摘要

陇东城壕—南梁地区位于鄂尔多斯盆地最有利的生油区内,是近几年陇东油田重点勘探和评价的区块之一,而中生界三叠系延长组长6油层组是该区块重要的勘探目标层位和产油层位。通过对城壕—南梁地区长6储层的岩石学、孔隙类型和储层非均质性分布特征的研究,认为城壕—南梁地区长6储层物性、含油性差异大、非均质性强;区内广泛发育的水下分流河道沉积微相砂岩具有孔隙度和渗透率都较好的物性条件,是有利的油气聚集场所。

Abstract

Chenghao-Nanliang area is one of the key blocks of exploration and evaluation in the Longdong oilfield in recent years. It is located in the most favorable oil generation area in the Ordos basin with Chang 6 sand bodies developed. Through the research of petrology, pore type and heterogeneity pattern on the  6 reservoir in the Chenghao Nanliang oilfield, we believe that the divergence of Chenghao Nanliang oilfield’s physical properties and petroliferous poperties is great, and the heterogeneity is strong. Underwater distributary channel deposit sandstones with good porosity and permeability are developed widely in the Chenghao Nanliang area, and are the favorable places for oil and gas accumulation.
