Abstract

The SIPC operated oilfield in Kazakhstan have experienced a long development period, and the geological characteristics of reservoirs are quite different. As a result, several problems occurred during the development process such as low water injection efficiency, difficulties in reservoir natural flow and stimulation, reservoir damage, severe sanding, high drilling cost and abnormal annulus pressure presence. Based on the analysis of the existing problems and considering the widely varying characteristics of this oilfield and current status of technology, countermeasures were proposed in which mature technologies such as high-efficiency water injection, sand-bearing oil recovery and high-efficiency drilling were adopted, intelligent reservoir protection agents were developed, and controllable cross-layer fracturing technology for complex sandstone was studied. The field application suggests that the proposed technical countermeasure can effectively improve water injection efficiency and fracturing stimulation effect, and solve the problem of sand production. The implementation of the countermeasures reduced reservoir contamination and drilling cost, and enhanced the development of the fields, and achieved target of cost-reduction and efficiency improvement during times of low oil prices. Further, this study may provide technical support for the smooth implementation of SIPC operated oilfield in Kazakhstan.
