摘　　要：以潜江凹陷广华寺组热储层为研究对象。根据中石化最新勘探成果和油田勘探开发过程中积累的大量基础资料,结合区域地质构造条件,通过精细构造解释,查明研究区新近系广华寺组呈现“南高北低、东高西低”的特征;运用属性分析和井震结合,确定热储层以辫状河沉积砂体为主,其砂岩沉积具有洼陷区较厚、边缘凸起区薄的特点,砂岩含水层具有埋藏较浅、分布面积较广、热储厚度稳定的特点。按钻孔测温及水分析资料分析结果,潜江凹陷现今地温梯度为2.8~3.9℃hm,平均为3.36℃hm。运用热储法计算得到的研究区可采地热资源量为18.94×106GJ,约合0.67×10^8t标准煤。The heat reservoir of Guanghuasi formation in Qianjiang depression is taken as the research object in this paper. According to the latest exploration results of Sinopec and a large amount of basic data accumulated during the exploration and development, combined with the regional geological structural conditions and fine structural interpretation, the Guanghuasi formation exhibits the characteristics of “south high and north low, east high and west low”. Through attribute analysis and well-seismic combination to determine that the reservoir is dominated by braided river sedimentary sand, the sand reservoir deposits have thicker depression areas and marginal bulge areas;the reservoir aquifers have shallower burial. The distribution area is wide and the thickness of the heat storage is stable. According to drilling temperature measurement and water analysis data analysis, the current geothermal gradient of Qianjiang depression is between 2.8-3.9 ℃ hm, with an average of 3.36 ℃ hm. The geothermal resource of the study area can be calculated by thermal storage method to be 18.94×10^6 GJ, about 67 million tons of standard coal.
