China Petroleum & Chemical News Network News Since the beginning of this year, in order to effectively ensure the safe and stable production of Daniudi gas field, North China Oil & Gas, based on the current gathering and transportation bottlenecks in the current surface system, pinpoints the power point, and strives to optimize the operation of the gathering and transportation system
.
The Lower Paleo gas reservoir is an important production replacement area for Daniudi gas field
.
Through the comparison of multiple schemes, the Engineering Institute designed a ground desulfurization layout based on "regional centralized desulfurization + decentralized gas collection" to adapt to the "14th Five-Year Plan" development plan of the ancient gas reservoirs
.
At present, 53 gas gathering stations have implemented secondary pressurization in Daniudi gas field.
With the extension of production time, the stable production period of secondary pressurization is gradually shortening.
This year, there will be 12 gas gathering station compressors from secondary compression.
Change to three-stage compression
.
In order to reserve the follow-up pressure reduction measures in the gas field in advance, the Engineering Institute carried out a double-cavity mixed oil and gas pressure boost test at the 58 gas gathering station in the Daniudi gas field.
During the test, the speed of the device was increased to increase the gas well production pressure difference, with an average daily increase.
The three gas gathering trunk lines of Daniudi Gas Field have not carried out corrosion monitoring work since they were put into production in 2005
.
Through the component test of the solid impurities purged from the gas field treatment station, 86% of the components are corrosion products of acid gases such as carbon dioxide and hydrogen sulfide
.
In order to ensure the safe operation of the gathering and transportation system, the Engineering Institute has formulated a combination of corrosion detection + corrosion treatment
.
At present, the existing Xiagu development wells have all realized the normal injection of corrosion and scale inhibitors
