Some Existing Problems on Subdivision Water Injection Technology during Extra-high Water Cut Period Xu Guo-min, Liu Ya-san, Mi Zhong-qing 2010, 29(4): 19-24.  DOI: 10.3969/j.issn.1002-302x.2010.04.005 Abstract ( )   PDF (1800KB) ( )   As Daqing Oilfield entered into extra-high water cut period, subdivision water injection technology has been executed in order to enhance the effect of water flooding development. The average water injection layers in single well are increased from four to seven. Because of the increasing of subdivision layer number in longitudinal layer, some problems on the technology need to be solved, such as installing packers over the thinner interlayer, configuring eccentric water injection allocator in the smaller stuck distance and so on. At the same time, because the number of separate layer water injection tool increases, it brings some problems such as difficult deblocking during replacing the string and poor well-flushing of string. Therefore, we need study the thickness standard of effective interlayer, develop separate layer water injection tool and test running, fishing tool adapting to thin interlayer and small stuck distance, study matched technologies which ensure effective deblocking and high-efficiency well-flushing to meet the technological requirements of subdivision water injection.

Cationic Polymer Drilling Fluid Used in Block H in Chad Jiang Zhi, Zhang Liang, Dong Xue-ming, Guo Bin, Yang Hong 2010, 29(4): 60-62.  DOI: 10.3969/j.issn.1002-302x.2010.04.015 Abstract ( )   PDF (1406KB) ( )   The original drilling fluid used in drilling operation for exploration and development in Block H in Chad was not adaptive to the geological traits. While drilling, cave-in and mud loss happened. That hurdled exploration and development. We want to gain a good drilling fluid for this aim through researching, experimenting and practicing. A good drilling fluid for Block H was gotten by analyzing cuttings samples and conducting a lot of experiments. Cave-in has never happened again since this kind of drilling fluid was used in drilling operation. And mud loss has not occurred since the excellent drilling fluid employed with its reasonable MW. It not only guarantees smooth drilling operation, but also avoids loss in pay zone and protects the reservoir. The adaptive drilling fluid system for Block H is achieved after practicing in a few wells.
