摘要
文昌某气田具有高埋藏深、低孔低渗、高温、轨迹复杂等特点,对钻井液储层保护、抗磨减阻、抗温性等方面提出极高要求。由于是目标区块是低孔低渗储层,如果储层保护效果不好,可能后期投产时会出现产量低于配产、甚至是无产量情况,所以钻井液方面须有良好的储层保护数据作为技术支撑。因此需要对油基钻井液的性能进行评价,并且重点对储层保护和油基滤饼清洗液进行了性能评价。
Wenchang gas field has the characteristics of high buried depth, low porosity and low permeability, high temperature and complex trajectory, etc.So high requirements for drilling fluid are put forward, such as reservoir protection, wear resistance reduction and temperature resistance. Because the target block is a low porosity and low permeability reservoir, if the reservoir protection effect is not good, the output in late production may be below the proration and even no production conditions may occur, so the drilling fluid must have good reservoir protection data as technical support. Therefore, it is necessary to evaluate the performance of oil-based drilling fluid, especially to evaluate the performance of reservoir protection and oil-based filter cake cleaning fluid.
