A Research Of Optimizing Cementing Technology At The Area Of Wangchang And ZhongShi

Cementing job is a comprehensive engineering by many types of workers. Cementing plan should be made according to the different job conditions, downhole conditions, formation and geology of each well, so cementing job under kinds of complicated conditions can be completed and cementing quality be assured.This project starts from collecting basic information, including geology, conditions, cementing, etc., of oil wells in Wangchang and Zhongshi these years, compares, analyzes and summarizes the well conditions, cementing technology and cementing quality of these two areas, analyzes the root cause, finds out the primary problems, carries out relative research, makes plans according to the different well conditions of these two areas, researches on cement and cementing technology meeting the cementing requirements of these two areas, realizes efective cementing of the two interfaces between the casing and formation, reaches the goal of enhancing cementing quality of these two areas, makes Jianghan Oil Field adjustment well cementing technology stay in advance domestically, obtains good social and economical efects.In the way of analysis, summary and field application, this project solves plenty of technological difficulties in production, optimizes cement and develops a cement system applicable to the different well conditions in Wangchang and Zhongshi areas;.It meets the special cementing requirements in Wangchang and Zhongshi areas, enhances the cementing quality, creates obvious social and economical benefits.
