长庆油田已钻区域普遍存在漏失，为保证井控安全，加入现有的堵漏材料进行堵漏，但普遍存在钻具水眼堵塞、井下仪器无信号、一次堵漏成功率低等技术难点。为此，进行无线随钻仪器及井下动力工具优选、研发配套的随钻堵漏浆体，满足通过性要求的前提下，实现漏层的快速封堵，形成了长庆区域随钻堵漏技术，现场应用百余口井，一次堵漏成功率提高23.54%，大幅缩短了堵漏时间，提高了堵漏效率，保障了安全快速钻完井。
In order to ensure well control safety， existing plugging materials have been added to the drilled areas of Changqing Oilfield for common leakage. However， there are technical difficulties such as water hole blockage of drilling tools， lack of signal from downhole instruments， and low success rate of one-time plugging. Therefore， wireless drilling instruments and downhole power tools have been optimized， and matching drilling plugging slurry has been developed to achieve rapid plugging of the leaking layer while meeting the requirements of permeability. This has formed the Changqing area drilling plugging technology， which has been applied in more than 100 wells on site， increasing the success rate of one-time plugging by 23.54%， significantly shortening the plugging time， improving plugging efficiency， and ensuring safe and rapid drilling and completion of wells.
