Thousand layer fracturing equipment in Tuha well in Petro China CNPC
Recently, with the help of our fracturing equipment, Petro China CNPC completed the fracturing of 1,000 layers in the Tuha Well, which is the first time in history that the production record has crossed the thousand layers. Compared with last year, the completion of the thousand layer fracturing work was 24 days earlier, an increase of 11%. Since the beginning of this year, Tuha Downhole has been focusing on the goal of improving quality and efficiency. With the help of our fracturing equipment, it has focused on increasing production speed, increasing market volume, and improving technological efficiency. The internal and external markets have gone hand in hand, and the workload has achieved unprecedented results. In this project, we provided fracturing equipment, fracturing head, fracturing valve, fracturing tree, fracturing check valve, fracturing gate valve, fracturing plug valve, fracturing manifold, plug valve manifold, Wellhead Christmas tree, ESD control panel, api6a valve, etc.
In the face of this year's increased exploration and development efforts in the oil field, with the support of our equipment, the fracturing workload has risen sharply, and the Tuha Downhole has firmly established the service concept of "achieving party A can achieve yourself", to "achieve fracturing" The transition time is shortened by more than 15%, and a single unit can fract more than 500 layers per year, and the winning team strives to complete more than 550 layers per year as the goal. Pioneering”, taking measures to local conditions, implementing precise policies, coordinating resource deployment, optimizing organization and construction, and significantly improving production timeliness.
Petro China CNPC optimized the production organization model in accordance with "six advance, four sharing" in the Tuha well, and continued to create a factory-like fracturing model of "regional concentration, construction starts when it arrives, construction stops when people leave, and people rest without stopping", paving the way for production acceleration "Fast Lane". Extend the production efficiency improvement to the whole process of production organization of each well, each equipment and each process. Focus on precise and precise management, strengthen the connection of key processes, compactly organize on-site production, and realize the construction of a well, preparation of a well, tracking of a well, and planning of a well.
On the basis of efficient organization and operation, CNPC has decomposed the "big indicators" of key projects layer by layer, and refined each link to wells, assigned positions, and identified responsible persons. With the help of our equipment, the reservoir reconstruction center, functional departments, and logistics support units focus on front-line production and provide strong support. With the help of our equipment, it is possible to track the progress of the design and compilation of construction plans in advance, identify construction risks in advance, and connect with manufacturers in advance for material needs. The advanced scope covers construction design, construction materials, construction preparation, risk assessment and other aspects to maximize production efficiency.
The four horizontal wells of the Jiji integrated general contracting platform in Zhundong Block were applied with the "zipper-type factory-like" fracturing mode. With the help of our equipment, the fracturing volume of 111 layers and 619 clusters was successfully completed. The construction success rate was 100%, and the design conformed to the rate 100%.
During the fracturing battle in the Charlekan Oilfield, it took 11 days and 21 hours to successfully complete the 22-stage fracturing transformation of 10 wells. With the help of our fracturing equipment, a new model of single-well fracturing organization was created, which refreshed the Charlekan. The regional fracturing fluid volume, sand volume, construction displacement, fracturing speed, transition speed and other records have shortened the well occupation period and completed 2 days ahead of the scheduled time.
Strengthen technical research, continuously improve service level, and cooperate with our company to jointly optimize the fluid and construction technology of Shabei 1 well, and our company will provide relevant equipment to ensure a successful exploratory well fracturing operation, and obtained 3 wells such as Shibei The workload of exploratory well fracturing and the scale of fracturing services have continued to expand; the first vertical well casing soluble bridge plug layered volume fracturing in Qinghai Oilfield was completed with high quality and efficiency 6 days ahead of schedule - Chai well fracturing construction, responsible, dedicated, responsible, Professional work style has been praised.
Science and technology is the primary productive force. Tuha Downhole continuously strengthens technological leadership, conducts diversified fracturing technology research, takes production as the leader, innovation as the driving force, technology for quality, and production needs based on new processes, new technologies, new models and The introduction of updated new equipment has injected new impetus into the downhole fracturing in Tuha, and innovative technologies have fully supported continuous and efficient construction and profitable development of key projects. With the help of our company's equipment, productivity has been greatly improved.
Firmly establish the concept of integration of geology and engineering, and optimize the fracturing design ideas and technical parameters in accordance with the differentiated design principle of "one well, one case, one layer and one policy", and improve the design pertinence, compliance rate and effectiveness.
In view of the technical problems such as poor production stimulation effect and short stable production period of conventional fracturing measures in low-porosity and low-permeability sandstone reservoirs in Qalekan Oilfield, Tuha Well combines the geological characteristics and lithological properties of oil reservoirs in the block and draws lessons from unconventional volume fracturing. The reconstruction technology adopts the idea of "reverse mixing" fracturing, and improves the fracture reconstruction volume SRV through "large fluid volume, large displacement, low viscosity liquid, low sand ratio and other unconventional fracturing techniques. to effectively improve the effectiveness of the measures.
Petro China CNPC has implemented a total of 11 wells in the Chalkan block of the Tuha Oilfield. So far, 8 wells have produced oil, and the post-fracturing effect is 4-5 times higher than that of conventional fracturing. It has won unanimous praise from Party A.
Petro China CNPC adheres to the fracturing construction of key wells. Management cadres and technicians are stationed in the wells throughout the process, strengthen on-site technical support, and take the seamless connection of industrial fracturing procedures as the management and control goal, grasp production information in a timely manner, and quickly deal with construction difficulties to ensure construction time. For special wells and key wells, technicians optimize the construction plan layer by layer, and carry out desktop deductions from liquid configuration, process optimization, risk prevention and control, and with the support of our company's equipment, to ensure smooth construction and significant production enhancement effects.
The good news of breaking the production record of thousand layer fracturing ahead of time made Tuha underground full of confidence and determination to successfully complete the annual production and operation goals, and formed a good atmosphere of "you chase after me and make persistent efforts" in Petro China CNPC, which more effectively drove Tuha The overall acceleration of the whole industry chain underground. The excellent fracturing equipment provided by our company has also been well received by customers and has been highly praised.
