Study on productivity of analog plastic oil in Tuyuke heavy oil field.

Method Incorporating rheology characteristics of crude oil and using general Darcy principle, productivity equation of analog plastic oil is deducted. Purpose To find out productivity equation suitable for analog plastic oil in Tuyuke oil field, analyze factors affecting well production and enhance development results. Result Test results comparison of 5 wells show that the described productivity equation for analog plastic oil is suitable for applying in the whole Tuyuke heavy oil field. Conclusion Tuyuke oil belongs to analog plastic fluids and its percolation in oil bearing zones doesn't conform to conventional Darcy principle. The appearance of this productivity equation sets a firm foundation towards detemining single well production and working out reasonable development technology and policy.
