PRODUCT DESCRIPTION

Abundant heavy oil resources in the world, China holds considerable reserves. Accelerate the pace of heavy oil development is the main way to increase production. However, due to heavy oil itself has a high viscosity, density, poor mobility, to the heavy oil has brought many difficulties, especially the structure of the sandstone formation as the main component areas, loose strata cemented. The continuous erosion in the formation fluid, the sand between the destruction of the cement, so that formation strength reduced, there are often sand collapse, blocking the oil sand pore. What is more, due to heavy sand-carrying capacity, oil production often occurs when the pump is forced to stop production of sand card, resulting in workover operations quite frequently, apparently to increase oil production costs, which seriously affect the production of crude oil, at present, domestic, foreign general to overcome the following two methods, one is the use of mechanical sand control method, which uses the tube pieces of metal around the wire sieve sand filling process, is winding down to the bottom steel mesh to prevent formation sand flow to the wellbore caused by card pump or full bore, and some cotton mesh metal sand, and sand the wire around the anchor with sand, although they are now well-established methods of sand, but also has its limitations. First, the wire-wrapped sand screens pieces after the filling process, as well the complex structure of the body, thus causing inconvenience to future workover. Second, the fine powder sand reservoir, due to the width of the gap around the wire-tube limit, the effect of its anti-poor sand. Third, the wire-wrapped screens pieces filled with sand operating costs high, in addition, such as metal cotton net sand, wire-wrapped sand anchor sand, which control the formation of sand as there are like wire-wrapped screens pieces filled with craft sand as the shortcomings, large scale production is difficult to use. Another method is to use chemical sand, making it a chemical reaction with the oil sands, cemented in the sand stratum, without affecting the normal oil production of heavy oil wells, the current foreign and domestic production of high-temperature solid sand agents, although some time can play a role in solid sand, but the period is short, and because the synthetic material is tetramethylsilane, the production is very difficult, resulting in sand consolidation agent expensive and affect its application.

High-performance composite oil sands cementing agent, it is not only adapted to the formation temperature higher than 200 ℃or more, can also be adapted to the formation temperature below 200 ℃or less. Play Sand obvious effect, the bond agent fast, high strength, on-site construction process is simple, short, very large scale value, is a new type of heavy oil sand consolidation agent for heavy oil production has opened up a New Road.

APPLICATION METHOD

The agent with 10% water mixture with a pump pumping into the formation, waiting 24 hours to pour.
