In the first half of the zhongyuan oil field oil and gas production task
As of June 30, zhongyuan oilfield crude oil output this year 1.21 million tons, 5.6 billion cubic meters of natural gas and sulfur of more than 110, ten thousand tons of oil and gas production during the first half of the complete success of the task. Since the beginning of the year, oil fields to increase the economic recoverable reserves as the main line, to speed up the rolling exploration and reservoir evaluation, to control the natural decline as the goal, constantly deepen the stereoscopic permeability reservoir adjustment in management, continue to expand the scale of the phased adjustment of low permeability reservoirs, strengthening process, refine the flood management and improving oilfield development effect.
Dongpu old rolling exploration research, hierarchical system continue to highlight zones of evaluation, based on the "bands, as" target zone, with rich oil and gas tectonic belt surrounding the complex fault block group, cultivate reserves increase, looking for developing high-quality reserves available. In who 22 north west - Ming nine blocks of 43, 329, bridge 8 favorable targets such as the fault block zone blocks, rolling appraisal well drilling of eight, to carry out the available reserves of 880000 tons. Capacity development in order to increase recoverable reserves, reduce development cost and improve the single well production capacity as the center, strengthen the design optimization of single well, perfecting injection-production relation in time, keep the formation energy, to ensure that the form stable production capacity, the implementation of the first half of the producing reserves of 3.76 million tons, production capacity is 60000 tons. Deepen the understanding of remaining oil potential and adjustment of key development unit management, refine injection-production management, perfecting injection-production matching, to ensure that built stable capacity, strengthen old stable foundation, in the first half of the new capacity of 27000 tons. Continue to increase the water drive reserves, increase recovery factor and slow down the natural decline Target, based on the overall research, the overall deployment, implementation, integration application form a complete set of technology, to carry out the classification of reservoir management and well group fine adjustments, vigorously promotes the flood management and effective water flooding, improve oilfield development effect, natural decline rate fell two percent year on year, composite decline rate fell 2.65% year on year.
Puguang gas field surrounding the production targets and annual maintenance tasks, monthly production plan, reasonable arrangement of overall arrangement QiZhan and joint device maintenance, corrosion protection and corrosion inhibitor batch priority, continue to strengthen the operation security and disposal of emergency incident, research for tackling key problems in the operation of the production of all kinds of problems, preliminary formed a "safe, steady, long, full and excellent" technology guarantee system operation, affecting the operation of gas field in secure further removes the bottleneck, effectively reduce the output fluctuation and maximise field full load operation. Gas recovery plant scientific working system of the gas well production, gathering and transferring system operation parameters were optimized in time, waiting for 4 sets successively completed dam 503 MAO QiZhan inspection etc. The key work, on the basis of the average daily production of mixed gas quantity more than 29.8 million cubic meters; Natural gas purification plant consideration of upstream and downstream of supply and demand, device maintenance, and the characteristics of the seasonal production, adhere to the "three early" execution of work and fully tap production potential, and ensure the full 10 series Load operation, the daily average deal with mixed gas quantity more than 29.8 million cubic meters, average daily receiving 6100 tons of liquid sulfur, six days ahead of time to complete production tasks in the first half of the year.
Closely around the oil and gas exploration and development of Inner Mongolia exploration area target task, elaborate organization researches battle, exploration of chagan sag, improving oil recovery research breakthroughs, positive progress has been made in research on reservoir evaluation. Oilfield operation ideas, adhere to the exploration and development integration from different professional experts, composed of five thematic research group, conducted in chagan depression hydrocarbon source rock, tectonic evolution, sedimentary system, hierarchical system evaluation and a series of intensive study, a batch of new knowledge and achievements, deploy, and drilling of auspicious 6-1 well, auspicious 8 well drill in thick oil layer. , auspicious 6-1 well find that three sets of oil-bearing series, 65 m thick, try oil flowing in the 6 sand group, is expected to be increased by using oil geological reserves of 3 million tons, chagan sag of important breakthrough in exploration and development. 4 piece in zion, and deployment of up to 34-6 reservoir appraisal well, 7 electric logging interpretation 17.4 meters / 9 oil layer, it is expected to use to carry out the geological reserves of 200000 tons of oil.
