摘要
山西省柳林煤层气区块利用“L”型井技术开采,单井产气稳定性良好,开采方便,产气量稳定,具有良好的煤层气地质条件和开发利用潜力。结合区块内的钻井施工实际情况,分析钻井液漏失情况,总结出适用于该区块钻井液堵漏技术,从而降低生产直接成本,为高效施工提供借鉴经验。
The exploitation of CBM in the Liulin block,Shanxi has used“L”typed wells.The single well CBM production stability favorable,convenient and yield stable with good geological condition and exploitation,utilization potential.Combined with drilling operation actual situation in the block has analyzed drilling fluid loss situation,summarized adaptable drilling fluid loss shut-off technology in the block.Accordingly production prime cost has lowered down,and offered reference and experiences for efficient drilling operation.
