Well Cementing Technology for Well Yangtan-1 with High Circulation Pressure

Room 510, North Star Times Tower, No. 8 Beichen Dong Road, Chaoyang District, Beijing 100101, China

摘要

摘要: 固井前循环高泵压一直是固井施工的难点。阳探1井下完尾管,循环51 h后,在循环排量仅为0.9 m³/min的情况下,泵压高达21 MPa,因此不得不在循环高泵压条件下固井,对施工安全和固井质量带来了严峻挑战。分析了阳探1井循环泵压高产生的原因,采取了一系列措施,包括:提高地面管汇耐压级别,改善钻井液和固井液流变性能,减少水泥浆附加量,适当延长水泥浆稠化时间,小泵速顶替等。候凝48 h后经CBL-VDL测井解释,固井优质封固井段占7%,合格封固井段占52.5%,较差封固井段占40.5%,水泥返高和固井质量满足后续施工要求。

Abstract: High circulation pressure prior to well cementing has long been a problem that remains unsolved. In cementing the well Yangtan-1, after running liner strings and circulating for 51 h, flow rate was still so low, only 0.9 m³/min, but the pump pressure was unreasonably high, up to 22 MPa. The well finally had to be cemented at high circulation pressures. Several measures were adopted to avoid accidents during cementing, such as using high strength surface manifolds, improving the rheology of drilling fluid and cementing fluids (prepad fluids, spacers, and cement slurries etc.), minimizing the volume of redundan t (additional) cement slurries, reasonably prolonging the thickening of cement slurry, and displacing at low pump rates. CBL-VDL logging data after 48 h show that of all the cemented length of the wellbore, 7% cemented are perfect, 52.5% cemented acceptable, and the rest 40.5%, are poorly cemented. Depth of the cement top in the annular space and the quality of the cementing job satisfy the needs for subsequent well operation.
