Development of China's offshore oil extraction equipment

First, China's exploration technology is further modernized. The geophysical acquisition and processing system realizes satellite positioning, digital processing, three-dimensional seismic, and computer phasing, which greatly improves stratigraphic resolution and accuracy of interpretation and judgment of oil and gas structures. In recent years, China has made a series of major discoveries of oil and gas resources, the reserve replacement rate has reached 100%, and new recoverable reserves have reached more than 150 million tons per year. The natural gas storage-production ratio exceeds 60: 1.

Secondly, the development of oil and gas fields has reached the world advanced level. We can not only develop large-scale oil and gas fields with simple self-assembling structures, but also small, fault-block, fracture-type, and composite concealed oil and gas fields. field. Downhole operation technologies such as early water injection, polymer injection, early sand control, thermal recovery, reinjection, acidification, fracturing, and viscosity reduction ensure high and stable production of oil and gas fields, making China's oilfield recovery rate reach 32%, and Daqing Oilfield has maintained stable production for more than 30 years Over 50 million tons / year, created a miracle in the development of the world's oil fields. China's crude oil output has broken through the situation of 160 million tons / year, and its production capacity has increased by 10-20 million tons annually.
