Abstract

An oilfield is a key overseas oil and gas production project of PetroChina, located in a rainforest environment. The oilfield is developed using cluster wells, and the problem of wellbore anti-collision is prominent. During the drilling process, the mud shale section is long and the clay mineral content is high. Some sections of the well have large coal seams, and the stability of the wellbore is poor. It is prone to mud wrapped drill bits and diameter shrinkage, resulting in complex accidents such as resistance and jamming during tripping, which affects the drilling efficiency. This article focuses on the drilling difficulties in A oilfield, optimizing the drilling fluid system, wellbore structure, drill bit, and drilling parameters to form a drilling quality and efficiency improvement plan for A oilfield with drilling fluid + wellbore structure + drill bit + drilling parameters as the core. Optimize the formation of a solid free polymer drilling fluid + plugging type low solid polymer system coal seam drilling fluid scheme to address difficulties such as poor stability of coal seam wellbore walls; Optimize and upgrade the wellbore structure plan based on the difficulty level of the wellbore trajectory; By evaluating and optimizing the performance of drill bits used in multiple wells in the early stage, a series of PDC drill bit models suitable for the formation in this block have been formed; Optimize drilling parameters based on the characteristics of different drilling operations and develop a drilling acceleration plan. The on-site application results show that a drilling quality and efficiency improvement plan has been developed for A oilfield, ensuring safe drilling of mudstone and coal seam sections, significantly accelerating drilling speed, and ensuring the smooth implementation of drilling operations and production capacity construction tasks in A oilfield^[1,2].
