| 摘 要： | 七里村油田长6储层埋藏浅,为多产层特低渗、低压、低产油藏.目前常规压裂工艺只能压开1～2层水平缝,因层状储层垂向连通性差或不连通,目前储层动用程度低,影响了产量和采收率.储层多水平缝压裂是解决这一问题的有效手段.在针对性研究水力喷射压裂水平缝压裂起裂机理的基础上,结合现场工程实际,研究了影响浅层丛式井水力喷射压裂施工的主要因素,提出了适应浅层水平缝压裂的工艺措施.现场先导试验表明:水力喷砂射孔压裂联作技术能准确定位水平裂缝启缝位置,解决当前常用的"蜡球暂堵"小间距"多水平缝压裂技术"启缝不确定的问题,现场应用效果明显. |

| Abstract: | The Chang-6 reservoir in Qilicun oilfield is a shallow reservoir with ultra-low permeability,low pressure and low yield.Conventional hydraulic fracturing can fracture 1 layer or 2 layers.The laminar reservoirs which contain several calcareous interbeds have low development degree because of bad vertical connectivity or no vertical connectivity.So the reservoirs have low yield and recovery factor.The multi-horizontal fracture fracturing of the laminar reservoir is effective way for enhancing their yield and recovery factor.The main factors of influencing the hydraulic jet fracturing effect of cluster wells in shallow reservoir are studied based on the hydraulic jet fracturing mechanism,and the technological measures for multi-horizontal fracture fracturing in shallow laminar reservoirs are proposed.The pilot test results show that,the hydraulic perforation-fracturing united technique can accurately determine the cracking location of horizontal fracture,which solves the uncertainty of the cracking location of horizontal fracture in the construction of wax-ball temporary plugging small-spacing multi-horizontal fracture fracturing technology.The pilot tests achieved good results. |
