Northwest Oilfield’s new process technology accurately implements "smart" strategies to obtain profitable gas

SINOPEC News Network Xun Yakela Gas Production Plant adheres to technological innovation in the process of oil and gas development, actively explores new processes and technologies, overcomes bottlenecks that restrict oil and gas production, and adopts independent research and development of new processes and technologies, and accurately implements “wise” strategies to obtain benefits Natural gas has become a “booster” for efficient development of oil and gas fields, increasing reserves and production.

Adjacent well gas lift production technology successfully "first show"

On January 29, well YK34H, the jet-stopping well, gained a new lease of life by gas-lifting the adjacent well YK20 with high-pressure gas, with a daily output of 32,000 cubic meters of natural gas.

With the extension of the development period of the Yakela gas field, the production capacity of some wells has been exhausted, and some gas wells have entered a low pressure and low production stage, and it is difficult for gas wells to stabilize production and increase production.

Well YK20 is 4 kilometers away from well YK34H.

Compared with the compressor gas lift method, the adjacent well gas gas lift extraction technology saves 10,400 yuan in gas injection cost per day.

Coiled tubing gas lift operations frequently "announce good news"

On March 31, with a whistling, the discharge nozzle of YK31 well ejected a flame of more than 5 meters high.

In order to solve the problem of gas production well lying down due to the accumulation of wellbore and rising water cut, the technicians set the goal of "bill production, efficiency improvement, and cost reduction".

　　In response to the fact that the process operation is difficult and the risk is high, the gas production plant has formulated detailed well control risk control measures.

　　In 2021, it is planned to complete 15 well-times of gas-lift drainage and gas production, which can accumulate 11,100 tons of oil and 78 million cubic meters of gas.

　　Hot oil circulation flushing helps "resurrection" of lying well health

　　"The oil pressure of Well Xinghuo 5 has recovered to 42.

　　Well Xinghuo 5 is a development well outside the Xinghuo 5 structure of the Yakra Fault Convex in the Shaya Uplift, 200 kilometers away from the construction area.

　　In order to allow this well to resume production as soon as possible, the Yacla Gas Production Plant took the initiative to use its technical advantages to simulate and analyze the coiled tubing operation, and from the positive injection of bubble release agent to braise the well, to the coiled tubing hot oil cycle flushing and coordinated installation of oil testing Methods such as processes are measured item by item.

　　On February 20th, at the construction site, the supervisor strictly clarified the well control emergency drill and safety technology.
