吉南油田萨探区块是近年来油田公司的重点建产区，科研人员通过前期大量的研究工作，建立了该区块北部斜坡区成藏模式，并结合多属性方法刻画断缝体和储层甜点发育特征，落实了北斜坡多个有利甜点区。

2023年底，位于北部斜坡区的萨11井试油获得高产油流。在此基础上，为进一步落实萨11断块上倾方向二叠系井井子沟组储层的含油性，公司部署上钻了萨11-4-3井。

今年9月中旬，萨11-4-3井完成压裂投产，排液3天见油。截至目前，已累计生产原油超500吨，这口井的高产进一步提振了准东区域效益建产的信心。

今年上半年，为进一步明确萨探区块主体开发技术路线，开辟完整试验区进行补能试验，研究院编制了萨11、萨105断块开发实验方案，优选萨105断块开展注水开发试验，优选萨11断块开展注二氧化碳开发试验。

The Satan block of Jinan Oilfield is the key production area of the oilfield company in recent years. Through a lot of research work in the early stage, the researchers established the reservoir formation model of the Northern Slope area of the block, and combined the multi-attribute method to characterize the development characteristics of fractures and reservoir sweet spots, and implemented a number of favorable sweet spots on the Northern Slope.

In late 2023, well Sa 11, located in the Northern Slope area, was tested and produced productive oil flows. On this basis, the company deployed and drilled well Sa 11-4-3 in order to further realize the oil bearing of the Permian Jingzigou Formation in the updip direction of the SA 11 fault block.

In mid-September this year, well Sa 11-4-3 completed fracturing and put into operation, draining liquid for three days to see oil. Up to now, more than 500 tons of crude oil has been produced, and the high yield of this well has further boosted the confidence of efficient production construction in the Jundong region.

In the first half of this year, in order to further clarify the main development technical route of the Satan block and open up a complete test area for energy replenishment test, the Research Institute prepared the experimental development plan of the SA 11 and Sa 105 fault blocks, and carried out the water injection development test of the preferred SA 105 fault block and the carbon dioxide injection development test of the preferred SA 11 fault block.
