The gaps between PetroChina and foreign counterpart in workover technology are as follows: the level of automation and intellectualization of tools and equipment is relatively low, the snubbing operation in gas wells characterized by HT/HP and high H2 S is lagged behind;water plugging in the long horizontal wellbore needs to be further developed, coiled tubing and its relevant equipment for ultra-deep well operation has to be optimized;informationization, standardization and big data application of workover operation need to be started. Based on this as well as the development status of workover technology in China and the technical difficulties faced in the future, eight suggestions for future development are put forward:(1) strengthen the dynamic understanding of reservoir and improve the pertinence of workover schemes;(2) develop the general overhaul technology in a systematical way to tackle issues of seriously problematic wells;(3) put more efforts into the research of horizontal well workover operation and develop relevant technology for long horizontal section operation;(4) improve the snubbing technology and extend its applications;(5) expand the capacity of coiled tubing operation and improve the level of special operations;(6) develop automatic workover technology into the field of artificial intelligence;(7) promote clean operation in an all-round way and build green oil and gas fields;(8) perfect the informationization construction to realize the sharing of workover resources.展开更多

In the course of PetroChina’s overseas oil and gas field production practice of more than 20 years, a series of characteristic technologies suitable for overseas oil and gas fields have been created by combining the domestic mature oil and gas field production technologies with the features of overseas oil and gas reservoirs, represented by the technology for high-speed development and stabilizing oil production and controlling water rise for overseas sandstone oilfields, high efficiency development technology for large carbonate oil and gas reservoirs and foamy oil depletion development technology in use of horizontal wells for extra-heavy oil reservoirs. Based on in-depth analysis of the challenges faced by overseas oil and gas development and technological requirements, combined with the development trends of oil and gas development technologies in China and abroad, overseas oil and gas development technologies in the future are put forward, including artificial intelligence reservoir prediction and 3 D geological modeling, secondary development and enhanced oil recovery(EOR) of overseas sandstone oilfields after high speed development, water and gas injection to improve oil recovery in overseas carbonate oil and gas reservoirs, economic and effective development of overseas unconventional oil and gas reservoirs, efficient development of marine deep-water oil and gas reservoirs. The following goals are expected to be achieved: keep the enhanced oil recovery(EOR) technology for high water-cut sandstone oilfield at international advanced level, and make the development technology for carbonate oil and gas reservoirs reach the international advanced level, and the development technologies for unconventional and marine deep-water oil and gas reservoirs catch up the level of international leading oil companies quickly.展开更多

PetroChina Company Limited（PetroChina） has all along regarded QHSE business as the consistent standpoint of self-developing. One of its most important tasks is to safeguard its staff＇s health, take precautions against accidents and protect the environment. Nowadays, information system has been recognizing as one of the most magic way to enhance management through out in the world leading oil company. In order to build an effective HSE system easily to implement and maintain, in January 2004, PetroChina invited IBM to help on conducting a feasibility study for Health, Safety and Environment （HSE） system. In March 2005, PetroChina kicked off the pilot phase of first enterprise-wide QHSE software implementation project. A very comprehensive selection of Essential SuiteTM （ESS）, the fully integrated, browser-based solution by ESS has been chosen for the implementation. PetroChina is collaborating with IBM Global Services and ESS on the pilot project.展开更多

The depth of well completion has even reached to 12 kilometers. Several countries, such as US and some European countries, are leading in the advanced deep and ultra-deep drilling technologies in the world. In recent years, nevertheless, PetroChina has also made big progress in mechanical penetration rate （ROP）, drilling period, amount of drilling bit used in a single well of deep drilling as well as in deep drilling equipments. Compared with the high-level technologies of complicated deep drilling in the world, PetroChina still has a long way to go.展开更多
