3月1日记者获悉,由中油测井天津分公司C1259作业队实施电动穿孔的D31-XX井重新搭建起循环通道。这是该项“绿色”去火工穿孔技术在海上的首次成功应用。

相较于传统的弹药爆破穿孔技术,本次使用的新型电动穿孔装备采用“去火工品化”绿色设计,可在复杂压力与斜度条件下,对油管进行电动钻孔,单孔平均用时在2分钟以内,可显著提升施工效率。同时,由于该技术采用非爆破作业方式,可从根本上消除传统爆炸穿孔的安全风险和解决药量控制难题,完全避免了火工品在油管射孔的残余能量对套管的伤害,也为建设方节约了火工品运输费用。

本次施工的井是大港油田部署在海上的一口侧钻井,经过一段时间生产,电泵流压持续增高、液量持续下降,初步判断为井下通道出现堵塞,需要进行穿孔作业打通井下循环通道。该井最大井斜87.57度,井内带压、管柱内含油气水,为作业带来一定难度。为高效完成作业,工程技术团队第一时间实施生产准备,高效完成电缆防喷器组装试压、通井及核心穿孔工序。

施工中,工程技术团队细致实施工艺管控,精准把控防喷器密封性压力测试、钻头测试、校深、钻孔压力控制等关键环节,确保了复杂工艺的安全高效执行,完成了3.5英寸油管的快速钻穿,为油井重新建立了井下循环通道,也为同类复杂井况作业积累了经验。

Recently, Anhui Science and Technology Department, Finance Department and Taxation Bureau jointly issued 《the notice on publishing the list of the first batch of high-tech enterprises in Anhui Province in 2021》, announcing the list of the first batch of high-tech enterprises in Anhui Province in 2021, among which our company Hefei CHENGONG Technology Co., Ltd. was listed.

In order to promote the development of China's high-tech industry, the Ministry of science and Technology issued 《the administrative measures for the identification of high-tech enterprises in 2008》. The measures put forward higher requirements for the identification of high-tech enterprises, including the need to have independent intellectual property rights, products (services) within the specified scope of high-tech fields supported by the state, the proportion of scientific researchers, R & D investment Income proportion of high-tech products (services), development organization and management level, transformation ability of scientific and technological achievements, etc. In order to successfully obtain the high-tech enterprise certificate, the senior leaders of the company paid close attention to it. On the basis of fully learning and digesting the recognition conditions of high-tech enterprises, the company formulated a detailed work plan. After many months of hard work, with the cooperation of various departments, the company defined the work nodes, concentrated key personnel, and conducted in-depth research and discussion on key and difficult problems. We have successfully completed the submission of online and written materials on time and quality.

This is the fourth time since our company obtained the national high-tech enterprise certificate for the first time in 2008. It is the full affirmation of our technology, management, service level and innovation strength by the government and the industry. At the same time, it also fully shows the increasing competitiveness of our company in the field of petroleum exploration and development and engineering software development in the petroleum industry, as well as the increasing economic benefits.

Our company will also take this opportunity to continue adhering to the concept of technology first and continuous innovation, further increase R & D investment and improve core technology competitiveness; Further promote the process of independent innovation and independent R & D, strengthen the company's technological innovation ability, and provide strong technical support for the rapid development of enterprises!
