摘　　要：东平1井位于鄂尔多斯盆地天环向斜中段圈湾子凸起,主要发育深灰、灰色泥岩,底部为张家滩页岩。从岩性、脆性指数、天然裂缝发育程度、地应力特征等角度,对东平1井长7储层进行体积压裂可行性论证。与国内外油田的页岩油藏进行比较,总体来看该储层存在实现体积压裂的可能性,但形成复杂缝网的可能性较小。Located in Ordos Basin, Dongping 1 well mainly developed dark gray, gray mudstone, and Zhangjiatan shale is at the bottom of zones. We demonstrate the volume fracturing feasibility of DP1 Chang 7 reservoir from several aspects, such as the reservoir rock lithology, rock brittleness index, natural fracture development status, stress conditions . Compared with domestic and foreign oil shale reservoirs, there is the possibility of a volume fracturing, but the possibility of forming complex seam is small.
