North China Oilfield, rich oil belt, overall re evaluation, incremental efficiency
China oil network news this year, Huabei Oilfield continue to adhere to the "rich area with overall evaluation of work principle, in accordance with the" active preparation, focus on cultivating and selecting the best proven work requirements, in order to find and implement the quality, efficiency, scale, reserves as the center, the overall evaluation of Lixian County slope, Chaheji and Suning vyk etc. the rich area, actively involved in Wulanhua sag evaluation, reserves, yield and benefit "three". As of August 24th, the new 15 million tons of proven reserves, the old re test oil 22, cumulative oil over 6000 tons.
Deepening the overall re evaluation of the rich oil belt, and bringing new breakthroughs in the new model. In Lixian County, Suning - King Zhuang slope zone seven, summarize and generalize the attention zone reservoir and accumulation mode, pay attention to geological knowledge innovation and technology research, focusing on Evaluation of aggressive new strata and new areas of new models, and develop new breakthrough. Among them, the western slope of Qianshan reservoir in Shulu based on in-depth analysis of the regional geological data, daring to build a new model of stratigraphic reservoir "inside Qianshan floor covering design, drilling Jingu 14-1X wells, Qianshan opened the formation of 30 meters, midway test Nissan 215 tons of high-yield industrial oil flow. The drilling success of the well proved the existence of the Qianshan formation oil reservoir in the west slope of Luxi mountain, which indicates the wide prospect of exploration in this area.
Promote the integration of evaluation, construction and production, and reproduce the new vitality of old oil fields. In recent years, Huabei Oilfield in accordance with the principle of "three overall", re evaluation of the Suning region to carry out the rich area with a whole, through the strengthening of sedimentary facies and sedimentary microfacies, logging interpretation standard reconstruction, to carry out reservoir review, focusing on the anatomy of known reservoir accumulation models and the main controlling factors, the conception of potential of different sand stacked body oil contiguous, evaluation of the implementation of 13, 12 wells to obtain industrial oil flow, to achieve 50 and 70, leaving 107 Ning reservoir contiguous, cumulative production of 390 thousand tons of construction, the first half of 2017, the district added 11 million 940 thousand tons of proven reserves, enhance the development efficiency.
Integration of exploration and development will be carried out so as to speed up the effective transformation of resources. Track pre discovery, pay more attention to early intervention and development feasibility evaluation, in accordance with the "no mining, no escalation, no use and no proven" principle, optimize the target, shorten the resource conversion cycle. Ulan flower area reported 2016 reserves of 43 million 520 thousand tons. Through the target screening, technical personnel involved in 4 broken (block) integration work in advance, the deployment of evaluation wells, LAN 11-5X, LAN 9-1X, LAN 8-1X, proven geological reserves of 3 million 80 thousand tons.
Push to make an inventory of assets very careful in reckoning the cost reduction. The company's priority evaluation of shallow buried depth, high yield area, and strive to complete the 37~38 wells with 32 wells drilling investment; optimization of oil testing procedures, reduce oil layers, large compression measures well; strengthen the old, lowering the efficiency of inventory of assets. This year, the company continued to carry out 142 wells reservoir review and re evaluation work, of which 50 wells by the newly discovered reservoir layer 144, has identified 30 old re test oil, complete test in 22 wells, 20 wells after re testing to obtain industrial oil flow.
