DEVELOPMENT AND APPLICATION OF THE WATER PLUGGING SYSTEM FOR THE THERMAL-PRODUCTION HORIZONTAL WELL IN BLOCK P-601
摘要
Abstract
A new type of the silicon salt resin system with the temperature and salt resistances was composed and developed in Block P601 of Chunfeng Oilfield in the light of the following problems:edge and bottom water encroachment/breakthrough,increasing serious watercut rise of the oil producers,poorer applicability of the existing plugging agent and so forth.The viscosity,erosion resistance and thermal stability were evaluated by the indoor tests.The test results show that the injected performances of the plugging agent are much better,the oil and water selectivity is pretty favorite,the water can be pronely plugged while the oil is just on the contrary,and moreover the performance of the water-resistant flush is also much better.With the help of the porous media model,the simulating test results of the plugging agent displacement show that the plug performances of the plugging agent are much better,5％ mass fraction can meet the requirements of the shutoff in the oil reservoir with 2 000×10-3μm2;the agent possesses a certain flush resistance,after flushed 50 PV by the injected water,much higher pressure is still maintained;the plugging agent possesses much better oil and water selectivity,the water shutoff rate can reach more than 80％,the oil blocking rate can less than 20％.Seven thermal-production horizontal wells were carried out in Block P601 of Chunfeng Oilfield.The field test shows that a certain effects were achieved in varying degrees for the seven wells,the comprehensive watercut was decreased,the cumulative oil was 8 443.9 t,the construction effects were obvious.The silicate resin system has provided a new choice for the water plugging of the thermal-recovery horizontal wells and furthermore presented the evidences for the field practice of the water plugging in the same type of the oil reservoir.关键词
