【摘要】 测声变遇阻是指在测井过程中,套管内钻井液受内因或外因影响而性能恶化、稠化沉积,从而造成声变测井仪器下行过程中遇阻的现象。大庆地区所钻调整井在测井过程中,测声变遇阻情况时有发生,严重影响了固井周期和固井质量,造成很大的经济损失。确定了造成大庆调整井测声变遇阻的原因,并且研制出了HT提切剂,HT提切剂同时具有抗水泥浆污染的功效。对于已遇阻井,通过优化筛选通井设施,使通井后的固井质量不受影响。更多还原

【Abstract】 The CBL-VDL logging resistance means that in the process of oil well logging process,the performance of the drilling fluid becomes bad,thicken and sedimentary in the casing because of the influence of the internal or the external factors,which can make the logging instrument obstructed in the process of measurement.In the oil well logging process of the adjustment well in Daqing oil field,the situation of the CBL-VDL logging resistance sometimes occur,which seriously affects the well cementation cycle and cementation quality and makes big economic loss.The reasons which result in the CBL-VDL logging resistance has been determined.And the HT has been developped to raise shearing force,at the same time the HT also has the anti-cement mortar pollution effect.For the well tighted pull,optimizing drifting installation can make that the process of drifting dosen’t affect the cementation quality.更多还原
