Digital Integration of Western Drilling Into the Entire Business Chain

Digital Integration of Western Drilling Into the Entire Business Chain

As of May 30, the three-parameter information tool developed by West Drilling cementing Company has been applied in the field for more than 300 Wells, and the accuracy monitoring pass rate is 98.1%. This is a microcosm of western drilling's innovative leadership. In recent years, western drilling has deeply implemented digital transformation, promoted the three major projects of "digital wellbore, digital well site, and industry and financial integration", integrated digital technology into the management chain of the whole business chain, accelerated the transformation to the strategic support of self-reliance, and helped the efficient exploration and benefit development of oil and gas fields.

The whole chain upgrade builds the "digital wellbore". The "1+14" two-level engineering operation Intelligent Support Center (EISC) has been fully established in the West Drilling, continuously optimizing functional modules such as intelligent analysis and auxiliary decision making, upgrading the EISC collector integrating drilling, repair and pressure testing, implementing multi-professional "EISC+" co-working, and promoting digitization of the whole life cycle of the wellbore. Build a "well site" brain, a "management" brain, and a "decision" brain. Carry out intelligent drilling and completion analysis and optimization, optimize and improve the acceleration template through EISC platform optimization, based on real-time drilling and completion data Integration Analysis System (RDAS), supporting MSE, fine pressure control and other characteristic technologies, improve the data analysis and optimization generation capacity of the whole drilling process, and accelerate the large-scale production of shale oil demonstration areas.

Tackle all aspects of the data "highway". Western drilling adhere to scientific and technological self-reliance, accelerate the construction of "well site network", independent research and development of a number of domestic advanced software systems covering drilling and completion, reservoir transformation, oil testing, completion of data acquisition tools such as drilling parameters measurement and basic research and sample manufacturing, development and application of digital cuttings analysis, overflow monitoring and early warning systems, configuration of "well site data center", Smooth data transmission "highway". Focusing on the technical bottleneck of high-speed data transmission while drilling, the continuous wave data transmission system has been independently developed to overcome technical problems such as signal noise suppression and efficient data encoding and decoding, forming key core technologies such as active disturbance rejection control + multi-phase modulation + digital signal processing, and increasing the data transmission rate by 3 times. In Mahu area, research on oil and gas evaluation technology based on knowledge Atlas was carried out, and module functions such as intelligent question answering and intelligent interpretation report generation were optimized, intelligent interpretation model was constructed, and intelligent interpretation application system of one-click logging was developed. The average drilling rate of Mahu area and Jimsar area reached 97.5% and 96.9% respectively.

Create a digital work team throughout the process. Western drilling to upgrade supporting automation equipment, research and development of remote orientation technology, fracturing "intelligent expert", remote oil testing, "one key cementing" and other systems, promote the "one key fracturing" control system, improve the automation of field operations, intelligent remote control level, promote equipment remote monitoring, production coordination command, engineering intelligent decision-making, safety early warning and forecasting work. Comprehensively implement the fracturing acceleration 3.5 mode, promote the application of the "Snow Leopard" one-key fracturing intelligent system, and optimize the horizontal well fracturing learning curve. Eight intelligent fracturing faces were launched in Jimsar, and a total of 24 Wells were completed in 1821 layers, an increase of 189.4%, and the number of construction stages in a single day increased by 45%.
