There are some problems about back pressure testing data when the deliverability test data is processed in Hetianhe gas field of Tarim basin, test production sequence changes leads to a certain errors to be in results of the analysis. The influence of production sequence to back pressure well test is analyzed on the basis of binomial deliverability formula, four error formulae for production system are given. Combined with field examples, it is recognized that increasing sequence has the smaller error. And increasing geometric factor between productions as far as possible, widening the gap between productions that will help to reduce errors, which provides a basis for the back pressure well test design. ©, 2015, Well Testing.

Cementing plug operation at north Tarim area in the Tarim oil field well is confronted with many challenges, such as depth, high temperature, high pressure, complex geological conditions, and. Cementing plug operation has the high risk and difficult, it s easy to have accidents of pole, sausage, no cement plug, which causes the major difficult to operation. In response to these challenges, it needed from vulgar to refinement of cementing plug operation, establish the elaborating management process. Through scientific analysis, design, construction and evaluation of the whole process of cementing plug, the success rate of cement plug is improved effectively, which provides the maximum protection for the life of oil and gas Wells, oil field development, environment protection and so on. © 2016, The Editorial Department of Well Testing.
