摘　　要：梁751区块目的层为沙四上纯下亚段、完钻层位纯下亚段,平均设计井深为3600 m,井眼轨迹采用三段制设计,稳斜段长达1400 m,施工难度较大。同时,本区块地层为高压低渗,临井施工过程中发生盐水侵、油气侵等复杂情况,固井质量难以有效保证。针对以上情况,通过优化轨迹设计,细化钻井液施工方案,优选钻具组合及钻进参数,达到了提速提效的目的,同时有效地保证了固井质量,为后期压裂投产施工打下良好的基础。The target formation in liang-751 block is the upper pure lower sub-member of ES4 and the lower pure sub-member of drilling horizon,the average designed well depth is 3600 m,the trajectory of the wellbore adopts a three-stage design,the stable inclined section is 1400 m long,the construction is more difficult.At the same time,the formation of this block is high pressure and low permeability,salt water invasion and oil and gas invasion occur in the process of adjacent well construction,so the cementing quality is difficult to guarantee.In view of the above situa⁃tion,through optimizing trajectory design,refining drilling fluid construction scheme,optimizing Bha and drilling pa⁃rameters,the goal of increasing speed and efficiency is achieved and the cementing quality is effectively guaranteed,it lays a good foundation for later stage fracturing operation.
