What is the single well output of shale gas in Fuling, Sinopec?

In May 1 1 day, with the successful commissioning of the Jiaoye 4-2HF well, the daily gas transmission capacity of Fuling shale gas field reached 3.037 million cubic meters, and the built capacity exceeded11million cubic meters/year, of which the daily gas production of the newly-put well reached/kloc in 20 14 years.

Since the beginning of this year, Fuling Shale Gas Branch has made all-round efforts in terms of production organization, production management and production management to ensure the efficient development of Fuling Shale Gas Field in accordance with the requirements of "building a demonstration and walking in the forefront" and "four modernizations" of standardized design, standardized procurement, information management and standardized construction.

Strengthen innovation drive and promote efficient development of shale gas. Fuling Branch actively explores a new model of "well factory" construction. By optimizing drilling fluid system and using new PDC bit and oil-resistant screw, the overall speed of drilling and fracturing construction is accelerated. The first wheel-rail drilling rig in China was used to carry out the "well factory" drilling test on the platform of Jiaoye 30, which achieved initial results, reduced labor intensity, reduced high-risk operation links, improved production efficiency and achieved economic benefits. In mid-April, the first "well-plant" mode cross fracturing construction of shale gas development in China Petrochemical Company ended perfectly, creating eight construction records, such as fracturing four sections every day for seven consecutive days, shortening the construction period by 40% and reducing the use of fracturing trucks by 35%. Dozens of central media such as CCTV and Xinhua News Agency witnessed this historical moment at the scene. At the same time, the surface flow of the test pit is continuously optimized, which solves the problem of a large amount of shale gas burning during blowout and testing, and forms a gas test flow of "testing while producing"; This technology has been successfully applied to 5 wells, and the shale gas emission of a single well has been reduced by 300,000 cubic meters. According to the production 100 wells, the carbon dioxide emission can be reduced by 58,000 tons, the shale gas output can be increased by 30 million cubic meters, and the efficiency can be increased by nearly 654.38 billion yuan. Actively explore the adaptability of fixed production and constant pressure production, and initially realize that fixed production is better than large differential pressure production, and the recoverable reserves of gas wells can be improved through long-term stable production of fixed production gas wells; The rubber industry 1HF well has a fixed production of 60,000 m3/ day, and has been producing for more than 5.2 days, with a cumulative gas production of 34 million m3. The calculated recoverable reserves of this well reach 654.38+200 million m3.

Strengthen organization and operation to ensure efficient production and construction. In view of the fact that the annual construction task is heavy, the time is tight, the requirements are high and there are many uncertainties, Fuling Branch arranges the work schedule from the aspects of pre-drilling project, equipment team, construction period and progress, and pays close attention to the control of starting point, time and nodes. All departments should coordinate production command to the site, implement standards and norms to the site, solve contradictions, eliminate sudden dangers, handle complex accidents to the site, check and accept the rectification to the site, strengthen on-site guidance, supervision and cooperation for production units, production links and production processes, coordinate and solve problems encountered in production operation, and ensure that production and construction work runs as planned and partially exceeds the plan. According to the mode of "four wells, six wells, single rig and double rig", the standardized well site construction was promoted, and the 18 double rig platform and 23 single rig platforms were completed. The average drilling and completion period is 65 days, which is 65,438+08 days shorter than that in 2065,438+03. There are 65,438+065,438+0 wells whose drilling and completion cycle is less than 70 days. The shortest drilling cycle is 47 days, shortened by 14 days. The average completion period is 7 1 day, which is 24 days shorter. The shortest completion period is 57 days, shortened by 16 days.

Strengthen strict management and mobilize the internal motivation of the construction unit. According to the deployment and requirements of the "Strict Management Year" activities of the headquarters and the oilfield, Fuling Branch has formulated the "Measures for Performance Appraisal of Service Teams" and related rewards and punishments, focusing on engineering quality, construction period, safety and environmental protection, and basic management. And in accordance with the principle of survival of the fittest, the service team is strictly assessed and hard to cash. At the end of March, the Branch awarded 530,000 yuan to the drilling team that ranked first in drilling speed and drilling completion cycle in Fuling work area, and awarded the title of "Excellent Drilling Team for Speed-up and Efficiency-Increasing". At the same time, we will continue to carry out the "six-to-six competition" for meritorious service, vigorously sum up and commend the typical experience of outstanding construction teams, create a strong atmosphere of advanced learning, catching up with the advanced and being advanced, and effectively stimulate the enthusiasm of all units for rushing to build. The rubber industry 16- 1HF well was drilled to a depth of 3960m and completed in 47 days. Well 8- 1HF in Jiaoye was drilled to a depth of 4,498 meters, which was completed in 59 days, setting a record for the shortest completion period of wells over 4,000 meters. The drilling depth of well 13- 1HF in rubber industry is 4300m, and the drilling is completed in 5 1 day, which realizes the horizontal section of one screw and one bit at a time 1560m, and creates a record of the shortest drilling cycle of well 3D in the work area. At present, Fuling shale gas field has drilled 79 wells, completed 46 wells and tested 27 wells, with a cumulative gas production of 430 million cubic meters and a sales volume of 427 million cubic meters. Built production capacity exceeds 654.38+065.438+0 billion cubic meters/year.
