New Progress and Prospects for Sinopec’s Petroleum Engineering Technologies
-
摘要:
近年来，针对深层特深层、非常规、低渗透油气勘探开发过程中存在的地层硬度和温度高及产能低等问题，中国石化攻关形成了9 000 m特深井安全高效钻井技术、页岩油工程技术和中深层页岩气工程技术等一批关键核心技术和装备，高效钻成了5口9 000 m以深特深井、10余口页岩油井和2口位移超4 000 m页岩气井，有力支撑了深地工程的顺利实施，保障了各类油气资源的勘探开发。但随着勘探开发的不断深入，石油工程技术面临着地质条件更为复杂等一系列技术挑战，中国石化应在安全钻井、高温高压测井和重复压裂等技术方面加快形成自主创新能力，注重新材料、绿色低碳技术的应用，打造更加成熟的、专业化水平更高的石油工程技术体系，为实现油气增储上产新目标提供技术支撑保障。
Abstract:In recent years, Sinopec has developed a number of key and core technologies and equipment to tackle the problems of hard formations, high temperature, and low production capacities in the exploration and development of deep, ultra-deep, unconventional, low-permeability oil and gas. These technologies include safe and efficient drilling technologies for 9000 m ultra-deep wells, engineering technologies for shale oil, and engineering technologies for medium and deep shale gas. These technologies and equipment were used to efficiently drill five ultra-deep wells with a depth of more than 9000 m, more than 10 shale oil wells, and two shale gas wells with a displacement of more than 4000 m. They provided strong support for the smooth implementation of deep-earth projects and guaranteed the exploration and development of all kinds of oil and gas resources. However, technical challenges, such as more complex geological conditions, will be confronted by petroleum engineering as exploration and development develop further. It is suggested that Sinopec should step up the pace of forming its innovation capacity in technical aspects such as safe drilling, logging under high temperature and high pressure, and refracturing. In addition, it should pay attention to the application of new materials, as well as green and low-carbon technologies and develop a more mature and professional system for petroleum engineering technologies. In this way, it can provide technical support for the new goal of increasing oil and gas reserves and production.
