Qinghai Oilfield Cleverly Uses Measures To Open Up The Venue Of Oil Increase And Achieves Daily Oil Increase Of More Than 180 Tons

Qinghai Oilfield has implemented 158 oil well measures, achieving a daily oil increase of 181.96 tons.

Qinghai Oilfield is the main gas source for the three provinces (regions) of Gansu, Qinghai and Tibet in western China. The main production area of the oilfield is located in the Gobi Desert of the Qaidam Basin, with an average altitude of 3,000 meters. Over the past 60 years, the Qinghai Oilfield has successively discovered oil and gas reservoirs such as Kunbei, Yingdong, Dongping, Zhahaquan, Yingxi, Yingzhong, Jianbei, and Kunteyi.

Since the beginning of the year, Qinghai Oilfield has focused on key oil reservoirs and blocks, focusing on the Gasi, Yingdong, Nanyishan, Wunan, Huatugou, Qiquan and other blocks to further promote the "four transformations" of oil well measures. Oil well measures were deployed for 729 wells throughout the year.

In order to continuously improve the pertinence and effectiveness of measures, the Qinghai Oilfield Technology Research Unit continues to tackle diversified and low-cost measures, constantly optimizes fracturing, plugging adjustment and other process systems, enriches the types of treatment fluid systems, comprehensively promotes sticky and slippery water, and carries out Localized evaluation of sand sources in shallow wells in Nanyishan and Qiquan and tests of formation water compound fracturing fluids have reduced single well costs and improved reservoir stimulation effects.

In response to the problem that some measures are not efficient and effective, Qinghai Oilfield vigorously promotes the transformation from "single well management" to "oil-water linkage". Up to now, the daily water injection volume of Qinghai Oilfield has reached 29,000 cubic meters, and the injection compliance rate of single wells is 91.8%.

At the same time, in order to improve the input-output ratio and increase more profitable oil, Qinghai Oilfield continues to promote the transformation from "quantity oil increase" to "profit oil increase".
