Practice of Pump in Optical Fiber Monitoring Technology in Shale Oil Wells of Qingcheng Oilfield
Staged multi-cluster subdivided volume fracturing technology is adopted in horizontal shale oil wells of the Qingcheng Oilfield,but the multi-cluster fracture initiation efficiency remains unclear.In order to evaluate the multi-cluster fracture initiation effectiveness and fracture propagation law,the first pilot test on pump in optical fiber measuring and testing technology in horizontal well in petroleum industry was carried out.This technology has unique advantages such as flexible process,convenient and efficient operation and low cost.The test results show that the staged multi-cluster subdivided volume fracturing technology of horizontal well can achieve 100%multi-cluster complete fracture initiation through perforation restriction + particle temporary blocking mode,but there are significant differences in the amount of sand and liquid inflow in each cluster,and the propagation of fractures in each cluster is uneven.This study preliminarily answers the effectiveness of multi-cluster fracture initiation that has beset the industry for many years,verifies the feasibility of pump in optical fiber monitoring technology in horizontal well casing,enriches the evaluation and testing methods for horizontal well volume fracturing,and provides an im-portant basis for the fracturing technology and parameter optimization of shale oil horizontal wells in the Ordos Basin.
