中国石油网消息：6月1日，从大庆油田获悉，大庆油田首个致密油Ⅱ类储层效益开发示范区——茂2区块投产至今，已累计产油3.13万吨，平均单井日产油8.6吨，一批重点水平井实现千米油层精准钻遇，油层钻遇率达100%，区块砂岩钻遇率、油层钻遇率等核心指标均超预期。

China Oil News: On June 1st, it was learned from Daqing Oilfield that since the production of the first tight oil Class II reservoir benefit development demonstration area - Mao2 Block began, a total of 31,300 tons of oil have been produced. The average daily oil output per well has reached 8.6 tons. A number of key horizontal wells have achieved precise drilling in the kilometer oil layer, with the oil layer drilling success rate reaching 100%. Core indicators such as the sandstone drilling success rate and oil layer drilling success rate in the block have all exceeded expectations.

茂2区块由大庆油田采油七厂管辖，属于致密油Ⅱ类储层。该储层砂体极薄、横向变化极快，开采时面临“井难钻、层难压、产难提”的难题，常规开发手段难以实现效益动用。

Block Ma2 is under the jurisdiction of the Seventh Oil Production Plant of Daqing Oilfield and belongs to the Class II tight oil reservoir. The sand body of this reservoir is extremely thin and undergoes rapid lateral changes. During the exploitation process, it encounters problems such as "difficult well drilling, difficult layer pressure control, and difficult production increase", and conventional development methods are unable to achieve efficient exploitation.

为有效解决传统地震预测难以精准识别薄油层的问题，采油七厂深化古地貌控砂理论，创新应用敏感频率属性分析技术，大幅提高储层预测精度，成功锁定复杂构造中的油层靶点。

To effectively address the problem of traditional earthquake prediction's difficulty in accurately identifying thin oil layers, the No. 7 Oil Production Plant deepened the theory of ancient landform control on sand production, innovatively applied the sensitive frequency attribute analysis technology, significantly improved the accuracy of reservoir prediction, and successfully identified the oil layer targets in complex structures.

为保障水平井随钻导向稳定，技术人员总结出“三个控制”靶前调整法和“四个紧盯”水平段跟踪法，引导钻头在薄层储层中精准穿行，为实现效益动用提供了有力保障。

To ensure the stability of the sidetracking technology in horizontal wells, the technicians have developed the "three control" target adjustment method and the "four close monitoring" horizontal section tracking method. These methods guide the drill bit to travel precisely through thin-layer reservoirs, providing a strong guarantee for achieving efficient production.
