Sinopec News Network News September 8th, with the successful completion of the fracturing construction of the 25th section of the Jiaoye 42-S2HF well, it marked the fracturing of the section 97 of the 4 wells on the Jiaoye 42 platform contracted by the Shengli Petroleum Engineering Downhole Operation Company.
It was a complete success, with an average of 4.
2 sections of fracturing per day, setting a new record for the time efficiency of a single set of diesel-driven zippers in the Fuling shale gas field
.
In order to build the platform into a benchmark demonstration project for improving quality, speed and efficiency, the company organized the production technical backbone to continuously improve and optimize the on-site construction plan in accordance with the design requirements of the well's fracturing construction, and strengthen the maintenance of equipment performance and the investigation of hidden dangers before construction.
, To ensure that the equipment can achieve uninterrupted construction while meeting the design displacement
.
The construction adopts the combination of large diameter + shunt manifold to implement the four-well "zipper->
In response to the high temperature and rainy operating environment, the company arranged personnel to go to the well in advance according to the work plan to organize construction, optimize the connection of pumping, pitching, and acid pumping processes, and strictly conduct on-site water supply and sand supply operations
.
In accordance with the work arrangement of "refined division of labor and reasonable rotation", and through the measures of "one case for one section, one person is responsible", the on-site control is in place around the clock, and the timeliness of connection of each link is improved
In order to ensure construction safety, cadres and employees overcome the adverse effects of epidemic prevention and control, high temperature and rain on construction, and actively carry out risk management and control and hidden danger investigation
.
Comparing with the "Checklist for Tagging and Locking out", conduct a comprehensive investigation on the implementation of the requirements for tagging and lockout on the job site
This company strictly controls the construction quality and earnestly implements the Fuling Shale Gas Company's gas testing business management assessment rules to ensure that construction parameters such as construction displacement and sand addition meet the design requirements within the pressure limit
.
Strengthen the on-site material quality inspection, and regularly check whether the viscosity of the liquid meets the design requirements
The Jiaoye 42 platform has accumulated 23 days of fracturing construction.
The completion of more than 4 stages (including 4 stages) in a single day accounts for 78% of the construction days.
Among them, 5 stages of fracturing in a single day are realized in 10 days.
The average daily construction time is 4.
2 stages, which is better than the first Fang's 26-day construction period was advanced by 3 days
