BIODRILL S合成基钻井液在垦利区块首次应用OACSTPCD
First Application of the Synthetic-Based Drilling Fluid BIODRILL S in Block Kenli of Bohai Oilfield
渤海油田垦利 9-1区块地层岩性复杂,且存在断层带,钻井过程中易发生泥岩水化分散和砂岩层井眼缩径等问题,井壁垮塌风险极大.针对该区块地层岩性特点和技术难题并结合环保要求,制备了一种复合型封堵材料 PF-MOSHIELD,构建了BIODRILL S合成基钻井液体系.该体系流变性能良好,抗钙、抗岩屑污染达 26%和 15%,封堵性、沉降稳定性、润滑性优异,高温高压砂盘滤失量 3.2 mL,静置 7d沉降因子为 0.53,极压润滑系数 0.082.BI…查看全部>>
Drilling operation in the Block Kenli 9-1 of the Bohai Oilfield has long been faced with high risks of borehole wall collapse resulted from complex formation lithologies,fault zones,shales that are easy to hydrate and disperse,as well as sandstones in which tight hole problem is frequently encountered.To deal with the borehole wall collapse problem a BIODRILL S synthetic based drilling fluid has been formulated.The BIODRILL S synthetic based drilling fluid i…查看全部>>
