民和盆地位于甘肃与青海交界处,夹于北祁连山与拉脊山之间,是一个中新生代发展起来的断、坳山间沉积盆地,具有丰富的油气资源,20世纪50-60年代进行过勘探工作。但到目前为止,只有青海国融红杉能源投资有限公司在海石湾布置探井开发,经过对以前地质资料了解,该区块地层不稳定、严重不整合接触,都会严重影响固井质量。所以要深入了解该区块地质分层,加大固井技术攻关,争取圆满的完成固井施工任务。总结固井经验,为以后民和盆地固井市场开发奠定基础。
Minhe basin is located at the junction of Gansu and Qinghai, sandwiched between the North Qilian Mountains and Lajishan, is a developed Meso-Cenozoic, inter-basin sedimentary basin, with rich oil and gas resources, carried out in the 1950s and 1960s Exploration work. However, so far, only Qinghai Guosheng Sequoia Energy Investment Co., Ltd. has deployed exploratory wells in the sea bay. After understanding the previous geological data, the stratum instability and serious unconformity contact in this block will seriously affect the cementing quality. Therefore, we should further understand the geological stratification of the block, increase cementing technology research and strive for the successful completion of cementing construction tasks. Summarize the cementing experience and lay the foundation for future cementing market development in Minhe Basin.
