Description

一种新型连续批量混浆设备A new type of continuous batch mixing equipment

技术领域technical field

本发明涉及石油装备领域，具体涉及一种新型连续批量混浆设备。The invention relates to the field of petroleum equipment, in particular to a novel continuous batch slurry mixing equipment.

背景技术Background technique

目前的固井作业中，常常需要连续性的批量密度均匀的高质量水泥浆，但由于现场作业条件的限制，例如现场水泥灰质量、供灰速度等因素，致使现有批量混浆设备的混合能力在1.5m3/min左右。如果高压泵送设备需要的排量＞1.5m3/min时，现有的批量混浆设备仅能间断性提供密度均匀的批量水泥浆，致使作业现场的批混混浆设备无法实现连续混浆，因此无法配合高压泵送设备完成全系列固井过程。In the current cementing operations, continuous batches of high-quality cement slurry with uniform density are often required. However, due to the limitations of field operation conditions, such as the quality of on-site cement ash, the speed of ash supply and other factors, the existing batch mixing equipment is mixed. The capacity is around 1.5m 3 /min. If the displacement required by the high-pressure pumping equipment is greater than 1.5 m 3 /min, the existing batch mixing equipment can only intermittently provide batch cement slurry with uniform density, so that the batch mixing equipment on the job site cannot achieve continuous mixing. Therefore, it is impossible to complete a full series of cementing processes with high-pressure pumping equipment.

为了满足超深井及复杂地层等特殊作业环境的大排量、高质量水泥浆作业需求，目前一般采用多台批量混浆设备同时作业，依次给高压泵送设备提供水泥浆，以此实现连续性的密度均匀水泥浆的提供，但是这种方法具有占地面积大，管线连接复杂，操作人员多，非作业准备时间增加，单次作业成本高。In order to meet the large-displacement and high-quality cement slurry operation requirements in special operating environments such as ultra-deep wells and complex strata, multiple batches of slurry mixing equipment are generally used at the same time to provide cement slurry to high-pressure pumping equipment in turn to achieve continuity. However, this method has the advantages of large floor space, complicated pipeline connection, many operators, increased non-operation preparation time, and high single operation cost.

另外，山地局促的井场施工环境及崎岖狭窄的施工路况不利于这种高压泵送设备配备多台批量混浆设备的作业模式，增加了运输成本的同时，增加了施工风险。In addition, the cramped well site construction environment in the mountains and the rugged and narrow construction road conditions are not conducive to the operation mode of this high-pressure pumping equipment equipped with multiple batch mixing equipment, which increases the transportation cost and construction risk.
