摘　　要：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 。Based on actual data of low oil layer of exploration well, combined with earth stress theory, the paper analyzes and demonstrates the fracture shape feature of it, draws a relations curve between measured fracture pressure gradient and depth, drives a mathematical analysis result. It is considered that the perforation position should be conducted at where is good oil bearing and physical property is comparatively better, washing well before fracture and setting packer in high viscosity fluid could raise success ratio of fracture. In addition, using the technique of low discharge capacity creating fracture, big discharge capacity adding sand and multiple fracture at one layer could increase fracture result.
