防气窜固井水泥浆体系研究

Optimization of anti gas channeling cement slurry system

固井操作是钻完井过程中最后的一个工艺,其操作的成效直接影响着油气井的寿命以及油气资源的开采量。近些年随着资源的不断开采,在固井过程中气窜现象表现比较突出。针对D区块在固井过程中存在的气窜问题展开了水泥浆性能体系研究。研究对于该区块的固井操作具有一定的成效,在该区块具有一定的推广价值。

Cementing operation is the last technology in drilling and completion process,and its operation directly affects the life of oil and gas well and the exploitation of oil and gas resources.However,with the continuous exploitation of resources in recent years,the phenomenon of gas channeling is more prominent in the process of cementing.Aiming at the gas channeling problem of D well during cementing process,the performance system of cement slurry was studied in this paper.The cement slurry system studied has certain effect for cementing operation in this block,and is worthy of further promotion in this block.
