截至5月下旬，南海东部首个整装开发稠油油田恩平18-1油田累产原油突破300万立方米，连续五年实现年产量零递减，创造增储上产新的里程碑。

恩平18-1油田平均水深约90米，是南海东部首个高泥质疏松砂岩稠油油田，油田含油面积大，但原油黏度高，压力传导慢，储层非均质性强，开采难度极大。

恩平18-1油田采用自源闭式能量补充技术，将深层地热水源注入目的层实现增能与高温降黏；同时，恩平18-1油田采用多项储层改造技术，在很大程度上改善近井地带储层，措施井平均单井产量提高一倍以上。

As of late May, the cumulative crude oil production of Enping 18-1 oilfield, the first fully developed heavy oil field in the eastern South China Sea, exceeded 3 million cubic meters, achieving zero decline in annual production for five consecutive years, creating a new milestone in increasing storage and production.

Enping 18-1 oilfield, with an average water depth of about 90 meters, is the first high argillous loose sandstone heavy oil oilfield in the eastern part of the South China Sea. It has a large oil-bearing area, but high crude viscosity, slow pressure conduction and strong reservoir heterogeneity make it extremely difficult to develop.

Enping 18-1 oilfield uses the closed-source energy supplement technology to inject deep geothermal water into the target layer to achieve energy increase and high temperature viscosity reduction. At the same time, Enping 18-1 oilfield has adopted a number of reservoir reconstruction technologies, which have greatly improved the reservoir near the well, and the average output per well of the measure well has more than doubled.
