As of June 3rd, China Petroleum and Petrochemical Company's innovative clean gas production integration "technology package" has been applied in 360 wells in Daniudi gas field and Dongsheng gas field, and the average production time rate of gas wells has increased by 4.
5%.
, Released gas well production of 300 million yuan, and a cumulative cost reduction of 164.
48 million yuan
.
The Daniudi gas field and the Dongsheng gas field will produce over 4.
5 billion cubic meters of natural gas in 2020, and are extremely important natural gas producing areas for Sinopec in the Ordos Basin
.
However, in the rolling development stage of the gas field, there are problems of non-clean production such as the need to inject methanol during the high-pressure period, and the need to vent and drain the liquid during the low-pressure period, resulting in direct carbon emission, and the widespread production of hydrogen sulfide in the lower paleocene layer, which restricts the company's clean and green development
To this end, the company established a tough project team to speed up the bottleneck technology research, successfully developed a clean gas production integrated technology package, and formed three key clean gas production technologies
The wellbore and the ground are integrated, and the clean production technology is innovated.
Integration of geology and engineering, innovative formation of high and low pressure mixed transport clean gas production technology in the second phase of the gas field pressurization mode, established 4 sets of production plans for new well/new layer throttling + old well/old layer simultaneous production, realizing new and old wells, Different pressure systems in the new and old layers have balanced production.
The integration of technology and economy has formed low-micro sulfur gas well bore medicament and wellhead atomized sulfur removal technology.
This "technology package" process has a wide range of applications and obvious application effects.
