摘要/Abstract

摘要： 中国石化页岩油勘探经历了早期选区评价及专探井试验、新一轮基础研究与先导试验两个阶段。通过早期页岩油专探井试验，发现陆相页岩油普遍存在“压不开、撑不住、返排低、稳产难”的现象，在国家“973 计划”、国家科技重大专项及中国石化相关项目的依托下，重点围绕页岩岩相特征、页岩油可流动性、页岩可压裂性进行了科技攻关，取得了积极进展，明确咸化湖盆纹层状页岩相是最有利岩相、较高成熟度页岩油是近期攻关的主要目标，初步形成了页岩油甜点地球物理预测方法和陆相页岩油工程工艺技术系列。“十三五”至“十四五”期间，中国石化将加强中高成熟度页岩油基础理论研究与技术攻关，力争实现页岩油规模性商业开发。

Abstract: In the process of shale oil exploration, Sinopec has gone through two stages: early block evaluation and exploration well test, and later new round of basic research and pilot test. Early shale oil exploration well tests found phenomena like difficult fracturing, unsustainability, low backflow and instable production for most wells developing continental shale oil. Supported by the National 973 Plan, the National Major Special Projects of Shale Oil and Sinopec Projects, technical researches focusing on shale facies, shale oil mobility and shale fracturability were carried out, and positive progress has been made. It has been found that laminated shale in saline lake basins is the most favorable lithofacies, and the shale oil with higher maturity is the primary target in recent research. A series of seismic methods for predicting shale oil sweet spots and engineering technology for continental shale oil have been formed preliminarily. During the period from the 13th Five-Year Plan to the 14th Five-Year Plan, Sinopec will intensify basic theory and technical research of shale oil with medium and high maturity, and strive to achieve large-scale commercial development of shale oil.
