With the development of heavy oil reservoirs, it faced a series of problems. Using the theory of thermal-hydrological-mechanical (THM) coupling, a predictive model of reservoir physical properties (RPP) after thermal recovery is established. Based on this model, the changing process of reservoir physical properties is simulated by the method of numerical simulation. The obtained results show that the sand production has a significant influence on RPP. By contrast with rock deformation, it has a smaller influence on RPP. The influence caused by the former is about 5~8 times than latter. During the period of steam injection, resulting from the movement of sand grain and expansion of reservoir, both porosity and permeability of reservoir are on the rise. Due to the sand production and reservoir compression, a reducing tendency is happened in the production period. The changes of RPP in reservoir are huge along the main streamline direction, and it might change because of the presence of high-permeability path.

Heavy Oil Reservoir

Henan Oilfield Xiaermen Qianbei block is the medium-deep heavy oil reservoir. Due to the high viscosity of crude oil, formation cementation loose, sand production and reservoir water-sensitive, the pre-trial is less effective. The problem is the inefficiency of steam injection, poor oil-steam ratio, sand production serious, the poor pump efficiency and the abnormal productions. It is important to improve the mobility of heavy oil in the formation and wellbore for the development. According to the reservoir characteristics and the experience of the primary development, the measures which include the high-pressure gravel packing sand control, insulated tubing of steam injection, anti-swelling agent reservoir protection, formation and wellbore viscosity reducer and rod sucker-rod pumping system are carried out in a pilot test of the four wells. After the pilot test, the oil-steam ratio increases from 0.08 to 0.55, the average daily oil production increases from 0.5 tons to 8.0 tons. The pilot test has achieved great success and promoted the application in medium-deep heavy oil thermal recovery in the entire block, simultaneously provided the basis for the efficient development of other similar blocks.
