随着经济社会的快速发展,对钻井技术提出了更高的要求。与常规直井相比,开窗侧钻井有自身的一些特点,即井眼小,井斜度较大,钻井风险大,固井施工难度高[1]。为了达到优化井身结构的目的,更好的巩固井的质量,保护储层,满足完井及试采的相关要求,降低固井的成本,需要我们对钻井固井技术加以研究和创新。开窗侧钻井固井技术以其独有的优势得到了广泛的应用。我国在开窗侧钻井固井技术方面与西方发达国家存在一定的差异,因此,我们必须从我国当前侧钻井固井的技术发展实际出发,加强对开窗侧钻井固井技术的研究和应用。
With the rapid economic and social development, drilling technology put forward higher requirements. Compared with conventional vertical wells, open side drilling has its own characteristics, that is, the borehole is small, the inclination of the well is large, the drilling risk is high, and the cementing construction is difficult [1]. In order to achieve the purpose of optimizing the structure of wellbore, to better consolidate the quality of the well, to protect the reservoir, to meet the requirements of completion and trial production, and to reduce the cost of cementing, we need to research and innovate the drilling and cementing technology. Open side drilling and cementing technology has been widely used due to its unique advantages. In our country, there are some differences between western countries and well-developed countries in the field of side-hole drilling and cementing technology. Therefore, we must start with the actual development of cementing technology in current lateral drilling and cementing in our country and strengthen the research and application of side-hole cementing technology.
