Fracturing equipment in Well Dixi 152_H in Xinjiang in Petro China CNPC
Well Dixi 152_H is located in the Dixi 121 well area of Xinjiang Oilfield. It is a key well in the development of Kelamei natural gas horizontal wells. Our project this time is to provide fracturing equipment for this well. The beneficial development of Well Dixi 152_H has extremely important guiding significance for the construction of natural gas production capacity in Xinjiang Oilfield. An important horizontal well for reference. At the same time, the benefit transformation of Well Dixi 152_H is of vital significance to the continuation of CNPC's follow-up market workload. We provide equipment such as fracturing equipment, fracturing heads, fracturing valves, fracturing trees, fracturing check valves, fracturing gate valves, fracturing plug valves, fracturing manifolds, plug valve manifolds, wellhead trees, ESD Control panels, api6a valves, and more.
The Dixi 152_H Well, with the help of our equipment, successfully set a new record: the large-scale fracturing construction of the 17 layers was efficiently completed in 3 days, setting a new record for the fracturing efficiency of natural gas horizontal wells in Xinjiang Oilfield; and completed a leap in efficiency: 24 With continuous operation of factory fracturing per hour, the daily average synergy efficiency of a single well is 5.53, which is 72.3% faster than the average synergy efficiency of the four wells completed earlier.
A special guarantee leading group was established, and with the help of our equipment, the "single well analysis" of the well was carried out in advance, and the well site survey, personnel equipment, resource allocation, first-level well control equipment for gas wells, quartz sand supply and protection, water resources Carrying out the “one-stop” process measurement of reservoir transformation, such as pulling and transportation, backup pressure relocation, and on-site standardization, accurately pre-arranging construction planning, and drawing a “four-in-one” “Gantt chart” of timetable, road map, operation map, and operational map , to achieve "wall chart combat".
The distance from the water supply source for the fracturing of the Kelamei horizontal well in the early stage is 120 kilometers. The tank truck can only pull it once a day, and the cost of the tank truck is high. After changing from the tank truck to the centralized water supply mode, not only the construction period is greatly shortened, but also the water supply cost is greatly reduced.
To play the main role of fracturing operations, engineers and technicians provide 24-hour technical support. At the same time, we pay close attention to the guarantee link, sort out the chain nodes, strengthen the communication with oilfield geologists, logging companies, water companies and other units, and coordinate the various work of fracturing construction. With the help of our company's equipment, we can eliminate risks and increase the speed.
With the help of our equipment, PetroChina's single-well project has achieved certain results: providing a "standard well" reference for parameters, costs, benefits, and efficiency for the later development of the Dixi area. It has revolutionized the high-cost and low-efficiency fracturing guarantee mode of long-distance water pulling of natural gas wells by tankers for many years, and created a precedent for the centralized water supply of natural gas wells in the Dixi area. Created a record of fracturing operation efficiency of natural gas horizontal wells in Xinjiang Oilfield.
Some time ago, the ninth fracturing team of PetroChina's downhole operation company efficiently completed the large-scale fracturing operation of the 17th layer of the Dixi 152_H well in the Dixi 121 well area of the Xinjiang Oilfield, setting a record for the fracturing efficiency of the natural gas horizontal wells in the Xinjiang Oilfield. . In this project, we provided a lot of wellhead Christmas tree equipment to innovate the water supply model for PetroChina, saving nearly one million for a single well in the oil field. The deep abdominal area of Kelamei natural gas horizontal well development has complex terrain, and it is difficult to maintain water supply for fracturing. For many years, tank trucks have been used for construction. Affected by the tank capacity, 24-hour continuous operation cannot be achieved in this area, the construction efficiency of a single well is low, and the cost of pulling water is high. In 2022, the volume fracturing process will be adopted, the average fluid volume of a single well and a single section will reach 1,000 cubic meters, and the construction period will be long. In order to solve this problem, the underground operation company actively cooperated with our company to promote the centralized water supply plan for fracturing, actively coordinated the water supply units, and worked together to open up the "last mile" of centralized water supply, and solved the water supply problem in the Dixi area. It has achieved the win-win goal of reducing costs and improving efficiency for both parties, and has also won development space for the company's subsequent market workload.
During the construction, managers at all levels of PetroChina's underground operation company served in the front, moved the front line forward, and firmly established the awareness of "paying the general ledger" and "military order". On-site diagnosis of such problems is carried out, and the solution is solved in the first time, so as to avoid complex and other stoppages on the site.
In the end, on the basis of the full cooperation between the downhole operation company and our company, the Dixi 152_H well achieved the shortest chain, the simplest link and the fastest speed, created a record of fracturing efficiency of natural gas horizontal wells in Xinjiang Oilfield, and created a unified regional well in Dixi. The production process provides multi-dimensional data support such as cost, technology, and parameters for the large-scale construction of the region. Our fracturing equipment has been successfully applied in PetroChina and has played a very important role. The excellent product quality has been well received by users and highly praised.
