7月31日，从跃探1H井现场传来捷报，这口井油气产量进一步攀升，喜获日产油5.65立方米、日产气35859立方米的高产油气流，续写了吐哈盆地致密砂岩气勘探的新篇章。

跃探1H井是继丘东洼陷致密砂岩气勘探取得突破后，公司针对小草湖洼陷下侏罗统致密砂岩气部署的一口风险探井，钻探目的是围绕台北凹陷主力气源灶，在小草湖洼陷源内构造稳定区，寻找浅埋高效的致密砂岩气新类型。

在这口井的钻探过程中，公司领导亲自牵头，公司企业首席技术专家和勘探开发研究院、采油工艺研究院负责技术支撑，勘探事业部负责现场组织实施，成立了跃探1H井工作专班。在地质导向过程中，工作专班地质技术组通过调整井眼轨迹，迅速钻遇第二套砂体，最终水平段储层钻遇率达到92.3%。在水平段钻进过程中，由于应力释放导致井壁垮塌严重，工作专班钻井技术组及时处理井下复杂情况，完成水平段进尺993米，达到设计目标顺利完钻。在压裂试油过程中，由于储层致密导致施工压力较高，工作专班试油技术组通过优化前置液比例降低摩阻，创造了单段最大加砂量181.1立方米的吐哈油田历史记录，最终顺利完成试油压裂任务。

On July 31, the good news came from the site of Yuetan 1H well. The oil and gas production of this well further increased, and the high production oil flow of 5.65 cubic meters of oil per day and 35,859 cubic meters of gas per day was obtained, which continued to write a new chapter in the exploration of tight sandstone gas in Tuha Basin.

Yuetantan 1H well is a risky exploration well for the Lower Jurassic tight sandstone gas deployment in Xiaocaohu Depression after the breakthrough of tight sandstone gas exploration in Qiudong Depression. The drilling purpose is to search for a new type of shallow and efficient tight sandstone gas in the stable structural area of the source of the Xiaocaohu depression around the main gas source in Taibei Depression.

In the drilling process of this well, the company's leaders personally took the lead, the company's chief technical expert, exploration and development research institute, oil production technology Research Institute was responsible for technical support, the exploration department was responsible for on-site organization and implementation, and set up a special team for the 1H well work. In the process of geological guidance, the geological technical group of the working group quickly drilled the second set of sand bodies by adjusting the trajectory of the hole, and the drilling rate of the final horizontal section reservoir reached 92.3%. In the process of horizontal section drilling, due to the stress release caused the serious collapse of the shaft wall, the drilling technical team of the working group dealt with the complex situation in time, and completed the horizontal section with a depth of 993 meters, reaching the design goal. In the process of oil testing by fracturing, due to the high construction pressure caused by tight reservoir, the technical team of oil testing by optimizing the proportion of pre-fluid to reduce the friction, and created a historical record of the maximum sand volume of 181.1 cubic meters in a single section in Tuha Oilfield, and finally successfully completed the oil testing and fracturing task.
