江家店位于山东省临邑县境内,构造上处于济阳坳陷惠民凹陷夏口断裂带江家店鼻状构造上,分夏502断块、夏509断块、夏510-斜1和夏503四个断块。主要含油层系沙三下、沙四段,含油面积3.33Km2,有效厚度15.2m,地质储量649×104t,标定采收率17.5%,可采储量113.6×104t。平均渗透率7.9×10-3um2,平均孔隙度13.0%,是典型的特低渗层状断块油藏,其开发特点是:初期部分井有一定自喷能力;天然能量较弱,初期产量递减较快,后期在低产量下生产;弹性能量不足,压力下降快,弹性产率低;油井自然产能低,压裂效果显著。
Located in Linyi County, Shandong Province, Jiangjiandian is structurally located on the nose-like structure of Jiangjiadian in the Xiakoukou fault zone in the Huimin Sag, Jiyang Depression. The Fenghuang 502, Xia 509, Xia 510-Xie 1 and Summer 503 four block. The main oil-bearing sand system is Sha3 and Sha4 with an oil-bearing area of 3.33Km2, an effective thickness of 15.2m, a geological reserve of 649 × 104t, a calibrated recovery rate of 17.5% and recoverable reserves of 113.6 × 104t. The average permeability is 7.9 × 10-3um2 and the average porosity is 13.0%. It is a typical ultra-low permeability bedded fault block reservoir. Its development features are that some of the wells have some self-spraying ability in the early stage, natural energy is weak and initial production decreases Faster, late production under low production; lack of elastic energy, pressure drop faster, low elastic yield; natural low production wells, fracturing effect is significant.
