以浅油层探井的实际资料为基础 ,结合地应力理论 ,分析论证了浅油层的裂缝形态特征 ,作出了实测破裂压力梯度与深度的关系曲线及数理分析结果。研究得出以下认识 :射孔位置应在含油性好 ,物性相对较好的部位进行 ,且压裂前必须洗井 ;高粘液坐封可以提高压裂成功率 ;采用低排量造缝 ,大排量加砂及一层多缝工艺可提高压裂效果 Based on the actual data of shallow oil exploration wells and the theory of ground stress, the fracture morphological characteristics of shallow oil layers are analyzed and the relationship between the measured fracture pressure gradient and depth and the results of mathematical analysis are given. The research concluded that the perforation location should be carried out in the areas with good oil and relatively good physical properties, and the well must be washed well before the fracturing; the high mucilage setting can improve the success rate of fracturing; the low displacement sew, large Displacement plus sand and a layer of multi-seam technology can improve the fracturing effect
