摘要
M油田位于伊拉克巴格达地区东部,石油资源储量较为丰富.研究区目的层Hartha储层压力系数为1.17左右,地层水矿化度较高,修井液目前采用一套高矿化度盐水工作液体系,为评价高矿化度盐水修井液对储层造成的损害情况,结合油田生产实际,通过修井液与地层水配伍评价实验和修井液与储层适应性评价实验,研究了高矿化度盐水修井液在修井时会对储层造成的损害情况.结果表明,修井液与地层水配伍,对储层的损害程度小于20%,损害程度较弱.
Abstract
To evaluate the damage caused by high mineralization drilling fluids to the reservoir,combined with the actual production of oil fields,through the compatibility evaluation experiment of drilling fluids and formation water and the adaptability evaluation experiment of drilling fluids and reservoirs,the impact of high mineralization drilling fluids on the reservoir during drilling was studied.The results show that low-temperature drilling fluids entering the reservoir will scale with formation water,forming scale in the near-well zone of oil and water wells,wellbore,or production equipment,thereby hindering fluid flow and reducing production efficiency.
