摘　要：中国致密油勘探开发起步较晚，综合分析判断致密油是非常规油气资源现实的勘探开发领域。近3年，中国石油持续推进致密油勘探开发理论研究与生产实践，坚持搞清资源、准备技术、突破重点、稳步推进的致密油基本定位，取得了在鄂尔多斯、准噶尔和松辽等六大盆地形成了3个超亿吨级规模储量区、获得6项新发现和新苗头的一批成果，创新完善了以致密油甜点区预测和提高单井产量为目标的地震预测、测井评价、水平井钻探和体积压裂4项关键配套技术，初步形成了2项中国陆相致密油成藏理论认识等勘探开发、理论认识与技术创新方面的重要进展。但是我国致密油发展总体处于起步和探索阶段，分析认为主要面临如何深化理论认识、实现关键技术突破、实现效益开发与降低成本等4方面的挑战。基于我国陆相致密油地质条件复杂、起步晚的实际情况，提出建议国家加大政策扶持力度，以及重点做好加强研究、注重应用，加强攻关、完善技术，加强探索、突出发现，控制成本、提高效益等4方面的工作建议，对加快中国致密油发展、保障国家油气能源安全具有重要意义。

Development, Beijing 100083)Abstract : China was late in tight oil exploration and development. Based on comprehensive analysis, tight oil is the realistic exploration and development fi eld of non-conventional oil and gas resources. In recent three years, PetroChina has made tenacious efforts for the theoretical study of tight oil exploration and development and clari fi cation of the resources, prepared for technological breakthrough and positioned tight oil exploration and development. As a result, the company has established three zones, each with the reserves exceeding 100 million tons, and six new discoveries in the six main basins like Erdos Basin, Junggar Basin and Songliao Basin. PetroChina has also created and improved four key technological families for prediction of the tight oil sweet-point zones as well as seismic prediction and logging evaluation targeted at improvement of single-well production, and developed two initial theories on China’s onshore tight oil accumulations. However, China’s tight oil development is still under the preliminary stage. The analysis shows there are four challenges, such as how to enhance theoretical study, how to make breakthrough in key technology, how to bring about high-ef fi ciency development, and how to reduce the cost. Thanks to China’s complicated onshore tight oil geological conditions, it is proposed that the State formulate more preferential policies to support this industry while focusing efforts for technological study and application, highlighting the discoveries, reducing the cost and improving the economic performance. Those suggestions are of great signi fi cance to acceleration of China’s tight oil development and the security of the country’s oil and gas supply.

Key Words : China’s tight oil, exploration and development results, theoretical study, systematic technology, challenges, suggestions
