1) backflow of proppant
支撑剂回流
1.
During the testing and exploitation of fractured wells,backflow of proppant often occurs and badly stings the surface flow system.
压裂井在施工后期进行排液测试及采气过程中,常有支撑剂回流造成刺坏地面流程的情况发生。
2) proppant backflow
支撑剂回流
1.
After fracturing unloading must be done, and too high unloading speed or uncontrolled open flow will make proppant backflow, so it is necessary to choose proper chokes and the amount of fracturing fluid in different stages according to the gas zone status, and to add fiber and sand in fracturing fluid to improve the operation.
由于压裂井均有一个压后排液过程,排液速度过快或不控制放喷均会造成支撑剂回流。
3) proppant extraction
支撑剂回采
1.
The proppant extraction prediction model for hydraulically created horizon-tal fractures;
水力压裂水平裂缝支撑剂回采预测模型
4) turning support
回转支撑
1.
Structural composition of the turning support has been described,different kinds of bearings have been simply compared,and required bearing mode has been selected preliminarily,via the analysis of external load and the calculation at different kinds of operating condition,to confirm the bearing mode which can satisfy the requirements.
介绍了回转支撑的结构组成,简单对比了各种轴承并初步选择所需轴承型式,通过外载荷的分析和各种工况下的计算,确定满足要求的轴承型号。
5) proppant
支撑剂
1.
Experimental Study on the Flow Conductivity of a new typed resin-coated sand proppants;
一种新型覆膜砂支撑剂导流能力室内评价研究
2.
Development of a high-strength acid-resisting proppant;
高强度耐酸支撑剂的研制与开发
3.
Measurement and analysis of proppant sphericity and roundness;
压裂支撑剂球度与圆度测量分析
补充资料：压裂液支撑剂
分子式：
CAS号：
性质：压裂时被压裂液带入裂缝，在压力释放后用以支撑裂缝的物质。常用的有砂子、树脂、涂层砂、中等强度陶粒、高强度的烧结铝钒土、氧化锆等。
